2. Safety
This section lists all the generally applicable
safety instructions and technical information.

InstallationandoperatinginstructionsWilo-ControlMS-L2x4kW 29
SAFETY English
Inaddition,alltheothersectionscontainspecic
safety instructions and technical information.
Allinstructionsandinformationmustbeob-
served and followed during the various phases of
the switchgear life cycle (installation, operation,
maintenance,transport,etc.)!Theoperatoris
responsible for ensuring that all personnel follow
these instructions and guidelines.
2.1. Instructions and safety instructions
This manual uses instructions and safety in-
structions for preventing injury and damage to
property.Toclearlyidentifythemforpersonnel,
the instructions and safety instructions are dis-
tinguishedasfollows:
• Instructions appear in bold and refer directly to
theprecedingtextorsection.
• Safety instructions are slightly indented and bold
andalwaysstartwithasignalword.
• Danger
Serious or fatal injuries can occur!
• Warning
Serious injuries can occur!
• Caution
Injuries can occur!
• Caution (instruction without symbol)
Substantial property damage can occur. Irrepa-
rable damage is possible!
• Safety instructions that refer to personal injury
appear in black and are always accompanied by
asafetysymbol.Danger,prohibitionorinstruc-
tion symbols are used as safety symbols.
Example:
Dangersymbol:Generalhazard
Dangersymbol,forexample,electricalcurrent
Prohibitionsymbol,forexample,Keepout!
Instructionsymbol,forexample,wearprotec-
tive clothing
The safety symbols used conform to the gener-
ally applicable directives and regulations, such
asDINandANSI.
• Safety instructions that only refer to materi-
al damage are printed in grey, without safety
symbols.
2.2. General safety
• The electricity network must be switched off
before any work is performed (installation, dis-
mantling,maintenance).Theswitchgearmustbe
disconnected from the electricity network and
secured against reactivation.
• The person operating the switchgear must notify
his or her supervisor immediately should any
faults or irregularities occur.
• Where damage occurs to electrical components,
cables and/or insulation, the switchgear must be
shut down immediately by the operator.
• Tools and other objects should be kept in their
designated places so that they can be found
quickly.
• The switchgear may not be installed in potentially
explosiveareas.Ariskofexplosionspertains.
These instructions must be strictly observed.
Non-observance can result in injury or substan-
tial material damage.
2.3. Electrical work
DANGER due to electrical voltage!
Improper procedures during electrical work
may result in fatal injuries caused by electrical
voltage! Such work may only be carried out by
aqualied electrician.
BEWARE of moisture!
Ingress of moisture will result in damage to
the switchgear. During installation and oper-
ation, pay attention to the permissible air hu-
midity and ensure the switchgear is installed
so it is overow-proof.
Our switchgears are operated with alternat-
ingorthree-phasecurrent.Thegoverning
national directives, standards and regulations
(e.g.VDE0100)aswellastherequirementsofthe
local energy supply company must be observed.
The person operating the switchgear must know
where it is supplied with power and how to cut off
thesupply.Aresidual-currentdevice(RCD)must
be provided by the customer.
Thesectionentitled"Electricalconnection"
must be observed when connecting the product.
Thetechnicalspecicationsmustbeobserved
strictly.Theswitchgearmustalwaysbegrounded.
Todothis,connecttheprotectiveearthconduc-
tor at the earth terminal indicated (;).Thecross
section of the cable for the protective earth con-
ductor must correspond to the local regulations.
If the switchgear has been switched off by
aprotective device, it must not be switched on
again until the fault has been corrected.
Use of electronic devices such as soft starters
or frequency converters is not possible with this
switchgear. Pumps must be connected directly.
2.4. Conduct during operation
When operating the switchgear, always follow the
locally applicable laws and regulations for work
safety, accident prevention and handling elec-
tricalproducts.Tohelptoensuresafeworking
practice, the responsibilities of employees should
beclearlysetoutbytheoperator.Allpersonnel
are responsible for ensuring that regulations are
observed.

30 WILOSE04-2015V05DINA4
English PRODUCT DESCRIPTION
Pushbuttons and LEDs on the housing are used
to operate the switchgear, display the operating
state,andsignalfaults.Thehousingcovermust
not be opened during operation.
DANGER due to electrical voltage!
There is arisk of fatal electric shocks oc-
curring when performing work on the open
switchgear. Only operate the switchgear with
the cover closed!
2.5. Standards and guidelines used
The switchgear is subject to various European
directives and harmonised standards. See the EC
declaration of conformity for precise information
about these.
Also,variousregulationsareusedasabasis
for operating, installation and dismantling the
switchgear.
2.6. CE marking
The CE marking is attached to the rating plate.
3. Product description
The switchgear has been manufactured with
great care and is subject to constant quality con-
trols. Trouble-free operation is guaranteed if it is
installed and maintained correctly.
3.1. Intended use and elds of application
DANGER - explosive atmosphere!
If the connected pump and signal transmitter
are used in potentially explosive areas, there
is adanger of fatal injuries from explosions!
Theconnected pump and signal transmitter
must always be used outside of potentially
explosive areas. Installation must always be
carried out by aqualied electrician.
The MS-Lift switchgear is designed for
• automaticcontrolof2nonEx-ratedpumpsin
lifting units and sewage chambers for water/sew-
age conveyance.
The switchgear must not
• beinstalledinpotentiallyexplosiveareas.
• beooded.
Intended use also includes observation of these
instructions. Any other use is considered to be
outside the intended use.
NOTE
Forautomaticcontrol,oatswitchesmustbe
provided by the customer.

3.3. Function description
The microcontroller-controlled Micro Control
switchgearisdesignedforcontroloftwoxed
speed pumps with level-dependent switching.
Levelmeasurementisviaatwo-positioncontrol
withaoatswitchforeachpump,whichneeds
tobeprovidedbythecustomer.Thepumpis
activated/deactivated automatically depending
onthelllevel.Ifafollow-uptimeisrequired,
thiscanbesetviaapotentiometer.Pumpcycling
is carried out after every pumping procedure.
Onreachinghigh-waterlevel(detectedviaasep-
arateoatswitch),avisualandaudiblewarningis
emitted and forced switch-on of the pumps takes
place.Thecollectivefaultsignal(SSM)isactive.
The current operating state is indicated via LEDs
on the front side. Operation is via 5 pushbuttons
onacontrolpanelattachedattheside.
Faults are indicated visually via LEDs and audibly
viaanintegratedbuzzer.Thelasterrorisstoredin
the fault memory.
