Uporaba puhala s stranskim kanalom je dovoljena samo v
mejah podatkov, navedenih na tablici naprave. Napotke v
naslednjih poglavjih je treba upoštevati in se jih držati.
Ta puhala s stranskim kanalom so primerna izključno za tran-
sport čistega zraka.
Uporaba za
• agresivne,
• grobe,
• lepljive,
• strupene,
• eksplozivne ali
• kondenzirajoče
medije ni dovoljena.
Dovoljena temperatura medija za črpanje pri standardni iz-
vedbi znaša od –20 °C do +40 °C. Trdne snovi v črpalnem
mediju ali nečistoče je treba odstraniti s filtriranjem pred vsto-
pom v puhalo s stranskim kanalom.
Kompresor s stranskim kanalom ni primeren za vgradnjo na
prostem brez dodatnih ukrepov. Kompresor s stranskim ka-
nalom je konstruiran za neprekinjeno obratovanje (S1). Do-
voljenih je največ30 preklopov na uro.
Kompresor s stranskim kanalom v serijski izvedbi ni prime-
ren za postavitev v ali črpanje eksplozivnih ozračij.
Posebne izvedbe za uporabo, ki se razlikuje od zgoraj opisa-
nih načinov uporabe, so na voljo na zahtevo. Predelovanje in
spreminjanje kompresorja s stranskim kanalom ni dovoljeno.
Pri posebnih napravah morate upoštevati navodila v dodatno
priloženih navodilih za uporabo in vgradnjo. Ta se v posa-
meznih podrobnostih razlikujejo od teh navodil za uporabo
in vgradnjo.
Kompresorje s stranskim kanalom Elektror odlikuje velika za-
nesljivost obratovanja. Ker gre pri kompresorjih s stranskim
kanalom za zelo zmogljive stroje, morate zaradi preprečeva-
nja telesnih poškodb, gmotne škode in škode na stroju stro-
go upoštevati naslednja varnostna navodila.

1.2 Mehanske nevarnosti
Mehanske nevarnosti so pri puhalih s stranskim kanalom
Elektror na podlagi njihove skladnosti s trenutnim stanjem
tehnike in zahtevami za varstvo in zaščito zdravja ustrezno
majhne. Za izključitev preostalih nevarnosti, do katerih
lahko pride pri ravnanju, priporočamo, da v vseh fazah ži-
vljenjske dobe naprave uporabite primerno zaščitno opremo
oz. jo nosite (prosimo, da upoštevate ustrezne napotke v
nadaljevanju).
1.3 Nevarnosti zaradi posegov v napravo
V notranjosti naprave med njenim delovanjem zaradi vrtečih
se delov obstaja visoka nevarnost telesnih poškodb. Napra-
vo pred odpiranjem, seganjem vanjo ali vstavljanjem orodij v
vsakem primeru izklopite in počakajte, da se vsi gibljivi deli
umirijo. Napravo v celotnem obdobju zanesljivo zavarujte
pred ponovnim zagonom.
Ravno tako zagotovite, da ne more priti do nevarnosti zaradi
ponovnega zagona po mirovanju, npr. zaradi prekinitve ali
blokade oskrbe z energijo.
1.4 Teža, varen položaj
Še posebej med transportom in postavitvijo obstajajo nevar-
nosti zaradi prevrnitve ali padca. Glejte 2.1 – Transport in
ravnanje ter 3.2 – Postavitev, montaža.
1.5 Število vrtljajev
Opozorilo!
Na sesalni nastavek se lahko prisesajo predmeti,
oblačila in lasje. Nevarnost telesnih poškodb!
Med delovanjem se ne zadržujte v bližini sesalne
odprtine. Ventilatorja ni dovoljeno uporabljati z
odprtim sesalnim nastavkom, zato ga je treba
pokriti z zaščitno mrežo po standardu DIN EN
ISO 13857 (nevarnost telesnih poškodb zaradi
rotorja!).

1.6 Sesalno delovanje
Puhala s stranskim kanalom ustvarjajo zelo visoko sesalno moč.
Opozorilo!
Na sesalnem nastavku lahko pride do sesanja
predmetov, oblačil in tudi las. Nevarnost poškod-
be! Med obratovanjem se ne zadržujte v bližini
sesalne odprtine. Puhala s stranskim kanalom
nikoli ni dovoljeno uporabljati z odprto sesalno
odprtino. Odprto sesalno mesto mora biti prekrito
z zaščitno rešetko v skladu z DIN EN ISO 13857.
Ne segajte v sesalno odprtino.
1.7 Temperatura
Opozorilo!
Ohišje motorja/puhala se med delovanjem se-
greje. Ko temperatura naraste nad +50 °C, mora
obratovalec (lastnik naprave) puhalo s stranskim
kanalom zaščititi pred neposrednim dotikom
(nevarnost opeklin!).
1.8 Zaščitno stikalo motorja
Pred začetkom uporabe kompresorja s stranskim kanalom je
treba pogonski motor zavarovati z motorskim zaščitnim sti-
kalom (ne velja za naprave s frekvenčnim pretvornikom). Pri
napravah s frekvenčnim pretvornikom je treba na frekvenčni
pretvornik priključiti in preverjati vgrajeno temperaturno tipa-
lo (PTC) ali temperaturni nadzornik (kontakt NC).
1.9 Nastajanje hrupa
Napotek!
Med delovanjem nosite zaščito sluha od dnevne
ravni izpostavljenosti 80 dB (A) in / ali najvišje
ravni zvočnega tlaka 135 dB (C).
Če ne upoštevate, lahko pride do okvare sluha.
Hrup, ki ga oddaja puhalo s stranskim kanalom, ni konstan-
ten za vsa področja zmogljivosti. Vrste oddanega hrupa poi-
ščite v preglednici na strani 18.
V določenih neugodnih posameznih primerih je potrebna
zvočna izolacija (priporočajo se meritve obratovalca). Zvoč-
no izolacijo mora izvesti obratovalec, da ne pride do prese-
ganja zakonsko dovoljenih maksimalnih vrednosti na delov-
nih mestih v okolici puhala s stranskim kanalom.
Nobena vrsta zvočne izolacije pa ne sme privesti do nedovo-
ljenega povečanja temperature v okolici nad največ+40 °C
pri pogonskem motorju.
1.10 Hitrosti
Opozorilo!
Da bi se izognili telesnim poškodbam, je na
žigosano ploščico motorja odtisnjeno
največja hitrost ne sme biti nikoli prekoračena.
Preti nevarnost mehanskega uničenja kompresor-
ja stranskih kanalov grozi.
To je nevarnost poškodb in smrti!
Vsaka komponenta kompresorja na stranskem kanalu ima
posamezne naravne frekvence. Te lahko vzbudijo določene
hitrosti kompresorja stranskih kanalov, kar povzroči možno
resonančno delovanje.
Ventilatorji stranskih kanalov so zasnovani tako, da običajno
ne pride do resonanc s konstantno hitrostjo delovanja.
Če puhalec stranskih kanalov deluje na frekvenčnem pre-
tvorniku, lahko v določenih okoliščinah pride do vzbujanja
s spremenjeno hitrostjo. Na te okoliščine vplivajo tudi spe-
cifične zahteve za namestitev uporabnika ali prezračevalni
priključek.
Če so te naravne frekvence v območju hitrosti kompresorja
stranskih kanalov, jih je treba izključiti z ustrezno parametri-
zacijo frekvenčnega pretvornika.
Največja frekvenca (glejte
tablico z močjo) Najmanjša frekvenca
50 Hz 5 Hz
60 Hz 5 Hz
> 60 Hz 20 Hz
1.11 Električne nevarnosti
Nevarnost!
Nevarnost zaradi električnega toka!
Komponente z električno napetostjo so pod
električnim tokom in povzročajo smrtne telesne
poškodbe!
Pred odpiranjem, poseganjem v napravo ali
vstavljanjem orodij izklopite delovanje naprave,
preverite odsotnost električne napetosti in napra-
vo zavarujte pred ponovnim zagonom.
2 INFORMACIJE O TRANSPORTU,
RAVNANJU IN SKLADIŠČENJU STROJA
2.1 Transport in ravnanje

3 INFORMACIJE O PRVEM ZAGONU
STROJA
3.1 Osnovni napotki
• Pred prvim in pred vsakim ponovnim zagonom je treba
izvesti skrbno preverjanje naprave glede njenega brezhib-
nega stanja. Naprave, ki imajo npr. pri dobavi ali namestitvi
vidne poškodbe, je treba dati strokovno preveriti.
• Postavitev, montažo, obratovanje in vzdrževanje sme izva-
jati samo strokovno ustrezno osebje s primernimi izkušnja-
mi in znanjem. Obratovanje po napačno izvedeni montaži,
vzdrževanju ali neusklajeni zamenjavi sestavnih delov
privede do nepredvidene uporabe in izgube jamstva. Tako
nastalo tveganje prevzame stranka ali sam obratovalec na-
prave.
3.2 Postavitev, montaža
• Puhalo s stranskim kanalom postavite zaščiteno pred vre-
menskimi vplivi, vremenom in sončnimi žarki. Glejte tudi
napotke za postavitev pod 1.1, Predvidena uporaba.
• Naprave ne izpostavljajte obremenitvam zaradi nihanja ali
udarcev. Dopustne vrednosti nihanja puhala s stranskim
kanalom: Glejte ISO 14694, BV-3.
• Puhalo s stranskim kanalom s podnožjem: Na mestu upo-
rabe napravo postavite na ravno, trdno, dovolj nosilno pod-
lago brez prenosa nihanja ali obremenitev.
• Puhala s stranskim kanalom je treba zavarovati pred zvijanjem.
• Noge oz. konzole kompresorja s stranskim kanalom so
konstruirane samo za lastno težo kompresorja.
• Odprto sesalno ali pihalno odprtino prekrijte z zaščitno
rešetko v skladu z DIN EN ISO 13857.
• Poskrbite za zadostno prezračevanje motorja. Dovoljene
temperature okolja pri:

3.4 Električni priključek
Napotek!
Dela, opisana v tem poglavju, sme izvajati samo
elektrotehnik. Priključek je treba izvesti v skladu z
vezalno shemo v omarici s sponkami in veljavnimi
predpisi na mestu izvedbe.
Kot pogonski motorji se uporabljajo motorji s trifaznim ali iz-
meničnim tokom. To je na napravi označeno s črko D (trifazni
tok, 3~) ali E (enofazni izmenični tok 1~).
• Pogonski motor je treba zavarovati z zaščitnim stikalom
motorja (ne velja za naprave, ki delujejo s frekvenčnim
pretvornikom). Za naprave, ki delujejo s frekvenčnim
pretvornikom, je treba na pretvornik priključiti obstoječi
nadzornik temperature (odpiralni kontakt) in izvesti anali-
zo.
• Preverite, ali se omrežna napetost ujema s podatki na
tablici naprave.
• Priključek zaščitnega vodnika je na voljo v omarici s
sponkami.
Napotek!
Pri obratovanju pogonskega motorja s frekvenč-
nim pretvornikom je treba dodatno upoštevati
naslednje:
• Oskrbovalna napetost frekvenčnega pretvornika
sme brez filtra motorja znašati največ400 V. Pri
daljših napeljavah, višjih oskrbovalnih napetostih
pretvornika in/ali prekoračitvi vršnih napetosti
(maks. 1.300 Vpk) na sponkah motorja, je treba
namestiti primerne priprave, npr. filter motorja za
njegovo zaščito. V zvezi s tem se obrnite na doba-
vitelja pretvornika. Če je filter motorja del obsega
dobave, ga je treba namestiti med pretvornikom
in motorjem. Poskrbite za dovolj prostega pro-
stora v stikalni omarici in upoštevajte predpise
za namestitev in montažo v navodilih za upora-
bo proizvajalca frekvenčnega pretvornika/filtra
motorja.
• Maksimalna dolžina napeljav med motorjem
in frekvenčnim pretvornikom ne sme preseči 20
m in jo je treba izvesti s primernim oklepljenim

dodanih spončnih/vtičnih povezav.
• Oklepni oplet na priključnem kablu mora biti
neprekinjeno in na obeh straneh, se pravi na
frekvenčnem pretvorniku in na motorju, elek-
trično nizko uporovno povezan z ozemljitvenim
sistemom. Na strani motorja je treba v ta namen
uporabiti primerna EMC-kabelska privitja, ki imajo
nizko uporovni stik z oklepom kabla po vsem
obsegu.
Nadaljnje informacije o primerni, elektromagnetno združljivi
namestitvi in montaži poiščite v napotkih v navodilih za upo-
rabo in montažo dobavitelja frekvenčnega pretvornika.
3.4.1 Vezava za trifazno puhalo s stranskim kanalom
Opozorilo!
Nevarnost zaradi razrahljanih in napačno prite-
gnjenih spojev!
Napačno pritegnjeni in razrahljani spoji povzro-
čijo električne udare, požare, stvarno in osebno
škodo!
Preverite rahlost spojev in jih pritegnite v skladu
s priteznimi navori v spodnji preglednici.

Preverjanje smeri vrtenja
Puhalo s stranskim kanalom vklopite. Smer teka rotorja se
mora ujemati s smerno puščico na pokrovu ventilatorja.
Smer pretoka zraka se mora ravno tako ujemati s smernimi
puščicami na ohišju dušilca zvoka. V primeru napačne smeri
vrtenja je treba zamenjati L1 in L3.
Zagon zvezda-trikot
Motorji z večkot 3,0 kW moči so predvideni za zagon zvez-
da-trikot na oskrbovalnem omrežju. Za neposreden vklop
(visok kratkostični tok v trenutku vklopa) se v zvezi s pogoji
posvetujte s svojim podjetjem za električno oskrbo.

4 PODATKI O OBRATOVANJU IN
UPORABI
4.1 Osnovni napotki
Upoštevajte napotke o predvideni uporabi, opisane v točki
1.1, ter varnostne napotke, opisane v točkah 1.2 do 1.11.
Če med obratovanjem pride do prekoračitve nazivnega toka
pogonskega motorja, preverite, ali se omrežna napetost in
frekvenca ujemata s podatki naprave.
Po zaščitnih odklopih kot npr. sprožitev zaščitnega stikala
motorja, reakcija nadzornika temperature (odpiralni kontakt)
ali zaščitni odklop prisotnega frekvenčnega pretvornika je
ponovni zagon naprave dovoljen šele po identifikaciji in od-
pravi vzroka motnje.
Pri puhalih s stranskim kanalom, ki jih ni mogoče uporabljati
v skladu z vsemi karakteristikami, lahko v primeru prevelike-
ga upora naprave pride do preobremenitve motorja (previso-
ka vhodna moč).
Če preobremenitve zaradi upora naprave ni mogoče izključi-
ti, je treba predvideti omejevalni ventil na tlačni oziroma na
sesalni strani.
Napotek!
Serije 2SD ni dovoljeno uporabljati z omejevalnim
ventilom kot trajno preobremenitveno zaščito.
Puhala s stranskim kanalom ni dovoljeno izpostavljati obre-
menitvam zaradi nihanja ali udarcev.
4.2 Delovanje frekvenčnega pretvornika
Z uporabo frekvenčnega pretvornika je možno obsežnejše
področje nastavljanja števila vrtljajev, pri tem pa se med
praznim tekom in maks. obremenitvijo puhala s stranskim
kanalom pojavi samo majhna razlika v številu vrtljajev, ki je
odvisna od obremenitve.
Za nemoteno obratovanje puhala s stranskim kanalom je
pomembno, da pretvornik izpolnjuje naslednje zahteve:
• Močpretvornika je enaka ali večja od moči motorja *)
• Tok pretvornika je enak ali večji od moči motorja *)
• Izhodna napetost pretvornika je enaka nazivni napetosti
motorja
• Napajalna napetost max. 480V, vključno s 5% napetostno
toleranco
• Frekvenca pulzov pretvornika mora znašati 8 kHz, ker
nižja frekvenca pulzov povzroča močan hrup motorja
•Vrednosti za največje in najmanjše frekvence so pod 1.10.
• Pretvornik mora imeti priključek za nadzornik temperature
(odpiralni kontakt)
*) glede vrednosti glejte tablico s podatki
Motor se lahko uporablja s trikotno ali zvezdno vezavo, odvi-
sno od vhodne napetosti pretvornika.

V primeru neupoštevanja se tok motorja nesorazmerno po-
veča in pogonski motor ne doseže nazivnega števila vrtljajev.
Napotek!
V nobenem primeru ni dovoljeno na pretvorni-
ku nastaviti višje frekvence (števila vrtljajev) od
frekvence (fB), ki je navedena na tablici s podatki,
ker sicer pride do preobremenitve motorja ali pa
uničenja puhala s stranskim kanalom zaradi po-
večanega števila vrtljajev. Na pretvorniku tudi ni
dovoljeno nastaviti tako imenovane „ojačitve (an.
Boost)“, ker bi tako prišlo do prekomerno visoke-
ga segrevanja pogonskega motorja. Temperatur-
na tipala je treba v zaščito pogonskega motorja
priključiti na ustreznih vhodih pretvornika. Motorji
z enofaznim izmeničnim tokom niso primerni za
delovanje s pretvornikom.
Obvezno je treba upoštevati napotke za namesti-
tev in varnost, navedene v priročnikih za uporabo
in namestitev, ki jih priložijo dobavitelji frekvenč-
nih pretvornikov, da tako zagotovite varno in
nemoteno obratovanje.
Zaščita s pomočjo zaščitnega stikala za okvarne tokove
(zaščitno FI-stikalo):
Frekvenčni pretvorniki IGBT načeloma ustvarjajo uhajave
tokove >=3,5 mA. Ti uhajavi tokovi lahko privedejo do na-
pačnih sprožitev v napravah, ki so zavarovane z zaščitnim
FI-stikalom za diferenčni tok 30 mA.
V primeru napake lahko okvarni tokovi tudi tečejo kot eno-
smerni tok po zaščitnem vodniku. Če je na oskrbovalni strani
potrebna zaščita s pomočjo zaščitnega FI-stikala, je treba
obvezno uporabiti zaščitno FI-stikalo z občutljivostjo na vse
vrste tokov (tipa B). Uporaba napačnega zaščitnega FI-sti-
kala drugega tipa kot B lahko v primeru napake privede do
smrti ali težkih poškodb.
Za izpolnjevanje standarda EN 61800-5-1 je treba povezavo

Obratovanje in priključitev na javna oskrbovalna omrež-
ja:
Večina frekvenčnih pretvornikov je predvidena za uporabo
na industrijskih oskrbovalnih omrežjih. Če naj se pretvornik
za uporabo priključi neposredno na oskrbovalno omrežje, je
morebiti treba v omrežno napeljavo vgraditi dodatne priprave
za odpravljanje motenj, na primer omrežno dušilko. Nadalj-
nje informacije najdete v navedbah proizvajalca pretvornika.
5 PODATKI O VZDRŽEVANJU
Obrabni deli so podvrženi priporočenim vzdrževalnim inter-
valom in zanje veljajo jamstveni zahtevki (glejte 5.1 do 5.4).
Življenjska doba obrabnih delov (krogličnih ležajev in filtrov)
je odvisna od obratovalnih ur, obremenitve in drugih vplivov
kot temperatura itd.
Ukrepe za in pri vzdrževanju in servisiranju smejo izvajati
samo osebe z ustreznim strokovnim znanjem in izkušnjami,
ki se za to področje redno usposabljajo. Pri tem je treba po-
leg ustreznih navodil za uporabo naprave in predpisov ter
priporočil celotne naprave upoštevati naslednje:
Intervali za preglede in vzdrževanje:
Odvisno od obratovalnih ur, obremenitev in pogojev uporabe
mora obratovalec sam določiti intervale čiščenja, pregledo-
vanja in vzdrževanja.
Takojšnji pregled in vzdrževanje:
Pri pojavu vibracij in nihanj, zmanjšani zmogljivosti zraka.
Napotek!
Popravila sme izvajati samo proizvajalec. Pri
popravilih: v primeru sprememb ali zamenjave
sestavnih delov, ki jih izvedejo tretje osebe, ne
prevzamemo nobene odgovornosti in jamstva.
5.1 Kroglični ležaji
Opomba!
Kompresorji s stranskim kanalom so opremljeni
z zaprtimi žlebastimi krogličnimi ležaji, ki jih ni
treba dodatno mazati.
Opomba!
Pri vzdrževanju in pred vsakim ponovnim zago-
nom preverite kroglične ležaje.
Obratovanje je dovoljeno samo z brezhibnimi
krogličnimi ležaji!
Opomba!
Pri pogostem speljevanju in ustavljanju je pot-
rebna predčasna zamenjava ležajev. Za določitev

1.1 Designated use
Operation of the side channel blower is only permissible
within the limits specified on the nameplate. The information
in the following sections must be noted and observed.
The side channel blowers are exclusively designed for con-
veying gaseous media without solids. Any solid matter or im-
purities in the medium to be conveyed must be filtered out
before they enter the side channel blower.
Use of the side channel blowers for
• aggressive
• abrasive
• sticky
• toxic
• potentially explosive or
• condensate-forming
media is not permissible.
The permissible conveyed medium temperature for the
standard version is -20°C to +40°C. Solid particles or con-
taminants must be removed by a filter unit before entering
the side channel blower.
The ambient temperature must not exceed +40°C or under-
shoot a minimum of –20°C.
The side channel blower is not suitable for installation out-
doors without special measures. The side channel blower is
fundamentally designed for S1 operation (continuous opera-
tion). However, a maximum of 30 switching operations per
hour are permitted.
The standard version of the side channel blower is not suit-
able for use in explosive atmospheres.
Special versions for applications not mentioned above are
available on request. Remodelling and modification of the
side channel blower are not permitted. In the case of special
equipment, the enclosed supplementary Operating and As-
sembly Instructions must be observed and adhered to. The
supplementary instructions differ in certain respects from
these Operating and Assembly Instructions.
Elektror side channel blowers offer a high level of operational
reliability. As the side channel blowers are high-powered ma-
chines, the safety instructions must be strictly observed in
order to avoid injuries, damage to objects and to the machine
itself.
1.2 Mechanical hazards
The mechanical hazards in Elektror side channel blowers
have been minimised in accordance with the current state
of the art, as well as the requirements for safety and health
protection. To eliminate any further risk on the part of the op-
erator, we recommend that suitable protective gear be used
and worn during all lifecycle phases of the appliance (please
refer to the instructions below).
1.3 Danger of hand injury
The rotating parts inside the appliance pose a high risk of
injury during operation. Before opening, reaching in or insert-
ing tools into the appliance, always shut it down and wait
until all moving parts come to a standstill. Make sure the ap-
pliance is reliably protected against restarting while work is
in progress.
Also make sure that no hazardous situation can occur as a
consequence of restarting after shutdown, e.g. as a result of
a power cut or blockage.
1.4 Weight and stability
Beware of falling hazards during transportation and installa-
tion in particular. Refer to 2.1 – Transportation and handling,
as well as 3.2 – Installation and assembly.
1.5 Suction effect
The side channel blowers produce a powerful suction effect.
Warning!
Objects, items of clothing and also hair can be
sucked into the intake port. Risk of injury!
Do not stand near the intake opening during op-
eration. The side channel blower must not under
any circumstances be operated with the intake
port open, and should, therefore, be covered with
a wire guard in conformity with DIN EN ISO 13857
(danger of injury from impeller!)

1.6 Blowing effect
Warning!
The blowing effect is very powerful on the ex-
haust side. Sucked in objects may be ejected at
very high speed (danger of injury).
The side channel blowers are designed for
delivery of clean air only. To reliably prevent the
sucking-in of foreign objects or contaminants,
which might be discharged, these objects have to
be removed before entering into the side channel
blower by installing a filter.
Do not reach into the exhaust.
1.7 Temperature
Warning!
The motor-/ side channel blower housing heats
up during operation. If the temperature rises
above +50°C, the side channel blower must be
protected by the operating company against
direct contact (risk of burning!).
1.8 Motor circuit breaker
Before putting the side channel blower into operation, be sure
to safeguard the drive motor with a motor circuit-breaker (this
does not apply to frequency-converter-operated appliances).
Where appliances are frequency-converter-operated, the ex-
isting temperature switch (normally-closed contact) must be
connected to the converter and evaluated.
1.9 Noise emission
Note!
Wear hearing protection during operation at a
daily exposure level of 80 dB(A) and above, and/
or a peak sound pressure level of 135 dB(C) and
above.
Failure to do so may cause hearing damage.
The noise generated by a side channel blower is not con-
stant throughout the performance range. For details of radi-
ated noise level, please refer to the table on page 18.
In some cases, sound insulation may be necessary (it is
recommended that emission levels be measured by the
operator). Sound insulation must be provided by the opera-
tor to avoid exceeding the statutory maximum levels at the
workplace and in the immediate vicinity of the side channel
blower.
No sound insulation of any kind whatsoever should cause
the ambient temperature to exceed +40°C at the drive motor
(this is not permissible).
1.10 Speeds
Warning!
The maximum speed stamped on the motor
rating plate must never be exceeded in order to
prevent personal injury. The side channel blower
is at risk of mechanical damage if the speed is
exceeded. This can cause serious injury or death!
Each component on the side channel blower has unique nat-
ural frequencies. These can be induced by certain side chan-
nel blower speeds, which may result in resonance mode.
The side channel blowers are designed in such a way that
resonance does not generally occur at a constant operating
speed.
This may be induced in certain circumstances when the
speed is changed if the side channel blower is operated on
a frequency converter. These circumstances are also influ-
enced by the customer’s individual installation situation or
ventilation connection.
These natural frequencies must be excluded by parametris-
ing the frequency converter accordingly should they be pre-
sent within the speed range of the side channel blower.
Maximum frequency (see
rating plate) Minimum frequency
50 Hz 5 Hz
60 Hz 5 Hz
> 60 Hz 20 Hz
1.11 Electrical hazards
Danger!
Danger from electric current!
Live components carry current and cause fatal
injuries!
Deactivate the device before opening it, reaching
into it or inserting tools into it; check that compo-
nents are not live and secure it against reactiva-
tion.
2 INFORMATION ON TRANSPORTA-
TION, HANDLING AND STORAGE OF

4 INSTRUCTIONS FOR OPERATION
AND USE
4.1 Basic information
Please observe the notes on designated use in section 1.1,
as well as the safety guidelines in sections 1.2 to 1.11.
If electrical current drops below the rated current of the drive
motor during operation, check to see if the mains voltage and
frequency match the appliance ratings.
After protective shutdowns, e.g. tripping of the motor circuit-
breaker, activation of the temperature switch (normally-closed
contact), or after a protective shutdown of the frequency con-
verter during FU applications, the appliance must not be re-
started until the problem has been identified and eliminated.
If the side channel blower cannot be operated over the whole
range of the characteristic curve, the motor may overload
if the system resistance is too low (excessive current con-
sumption). If the possibility of overload due to system resist-
ance cannot be excluded, a relief valve must be provided on
the discharge or intake side.
Note!
It is not permitted to operate the 2SD range
with a relief valve as permanent overload protec-
tion.
The side channel blower must not be subjected to vibration
or impact loads.
4.2 Frequency converter operation
A frequency converter is used, allowing a wide range of
speed adjustments. There is only a small, load-related differ-
ence in rpm between idle state and the max. load of the side
channel blowers.
To ensure trouble-free operation of the side channel
blowers, it is important that the converter meet the
following requirements:
• Converter output equal to or greater than motor power
output *)
• Converter current equal to or greater than motor current *)
• Converter output voltage equal to rated motor voltage
• Supply voltage max. 480V, including 5% voltage tolerance
• The pulse frequency of the converter should be 8 kHz,
since a lower pulse frequency can cause very noisy motor
operation.
• The values for the maximum/minimum frequency can be
found at 1.10.
• The converter should have a connection for a temperature
switch (normally-closed contact)
*) Refer to the rating plate for data
The motor can be operated in a delta or star-point configu-
ration, depending on the input voltage of the converter.
The following U/f assignments must be configured at the
converter.
fBand UB= refer to rating plate
If this is ignored, the motor current will increase disproportion-
ately and the drive motor will fail to achieve its rated speed.
Warning!
To avoid personal damage, destruction of the
side channel blower or motor overload, a higher
frequency (speed) than the frequency (fB) speci-
fied on the rating plate must never be set on the
converter otherwise the motor may be overloaded
or the side channel blower destroyed due to
the increased speed. The temperature sensors
are connected to the corresponding converter
inputs to protective the drive motor. Single-phase
alternating current motors are not suitable for
converter operation.
It is absolutely essential that you observe the
installation and safety instructions described in
the respective operating or application manuals
provided by the frequency converter supplier to
guarantee a safe and trouble-free operation.
It is also important to note that special ambient
conditions may lead to a high level of contamina-
tion of the cooling fins with the FUK devices. The
frequency converter switches offif the cool-
ing output on the cooling fins is not adequate.
Regular cleaning is required for devices in these
environments.
Note!
The following times apply for the respective
device motor output class (see rating plate) with
run-up/expiry as well as speed changes in order
to to avoid high component loads and faults in
the converter operation:
Device motor output Run-up time
[s]
Expiry time
[s]
Motor output < 0.25 kW 5 10
0.25 kW < Motor output
<=3.0 kW 10 20
3.1 kW < Motor output
<= 7.5 kW 20 40
7.6 kW < Motor output
<= 11.0 kW 30 60
11.1 kW < Motor output
<= 30.0 kW 30 100
A uniform run-up and expiry must be guaranteed within the
run-up and expiry times.
No speed changes must occur during operation that exceed
the speed change during run-up and expiry.
Protection by residual-current-operated circuit breaker
(FI circuit-breaker):
IGBT frequency converters produce discharge currents of
>=3.5 mA due to their design principle. These discharge cur-
rents can lead to unwanted tripping in systems protected by

15
EN
Operating and assembly instructions 1SD, 2SDwww.elektror.com
9016329 01.20/09
a 30 mA-FI circuit-breaker.
If a fault occurs, fault currents can also discharge through the
PE conductor as direct current. If protection is needed on the
supply side by means of an FI circuit-breaker, then an ACDC
sensitive (type B) FI circuit-breaker must be used. Use of an
FI circuit-breaker other than type B can cause death or seri-
ous injury if a fault occurs.
To meet the EN 61800-5-1 standard, the PE conductor must
be duplexed and routed through separate terminals or have
a cross-section of at least 10 mm² Cu.
Operation and connection to public grids:
See 3.5
5 INSTRUCTIONS FOR MAINTENANCE
Wear parts are subject to the recommended maintenance in-
tervals and are an element of valid warranty claims (see 5.1
to 5.4). The service life of wearing parts (ball bearings and
filters) depends on the operating hours, the load and other
influences, such as temperature, etc.
Maintenance and servicing may only be performed by per-
sons with the necessary expertise and regular training. In ad-
dition to the appliance’s operating instructions and the regu-
lations and recommendations for the system as a whole, the
following points should be observed:
Inspection and maintenance intervals:
The operator must set the cleaning, inspection and mainte-
nance intervals himself according to operating hours, load
and operating conditions.
Immediate inspection and maintenance
The side channel blower must be inspected immediately if
vibrations or reduced air flow are observed.
Note!
Repairs must be carried out by the manufacturer.
We cannot accept any liability for modifications
or the replacement of components carried out by
third parties.
5.1 Ball bearings
Note!
The side channel blowers from Elektror are equip-
ped with sealed deep groove ball bearings, which
do not require relubrication.
Note!
Check the ball bearings during servicing and
prior to recommissioning.
Operation is only permitted with flawless ball
bearings!
Note!
In the event of frequently starting up and shutting
down, premature replacement of the bearings
will be required. Determining the time for repla-
cing the bearings is the sole responsibility of the
maintenance and servicing personnel, who must
make a safety judgement.

Ball bearing change recommendation
- Prior to reaching the minimum service life
- 30 months following delivery at the latest
- Check after 6 months’ storage time; change if necessary
5.2 Micro-filters
The degree of clogging of the filter elements should be
checked at regular intervals, depending on the ambient
conditions / conditions of use. This means that the user is
responsible for ensuring that the filters are permeable. The
micro-filter must be positioned horizontally to prevent con-
tamination entering the side channel blower during mainte-
nance work. With vertical micro-filter installation, the com-
plete filter must be removed from the unit before starting
cleaning/maintenance.
5.3 Relief valve
The relief valve is a safety valve and its operation must there-
fore be checked at regular intervals depending on application
conditions. The operating side must be closed during inspec-
tion. The relief valve must respond at the maximum pressure
value.
Note!
Repairs must be carried out by the manufacturer.
We cannot accept any liability for modifications
or the replacement of components carried out by
third parties.
5.4 Cleaning
There is a high risk of injury on the inside of the device due to
rotating parts during operation. Decommission the device in
all cases and wait until all moving parts have stopped before
opening, reaching in or inserting tools into the device.
Secure the device reliably against it being accidentally re-
started during the entire period.
Also make sure that no other dangerous situation can arise
when restarting after a standstill, e.g. as a result of a power
failure or blockages.
Cleaning or maintenance must not lead to damage or modi-
fications to the device and its components that would influ-
ence safety or health protection and, for example, impair the
balanced state of the impeller.
When starting up the side channel blower, make sure that
all tools or other foreign objects have been removed from
inside the device and that all covers and protective grilles
have been attached correctly.
