1. INTRODUCTION
Thank you for choosing an Alessi DC to AC inverter. The Alessi inverter series are one of the most
sophisticated inverters available today. With high reliability, efficiency and sine quality as our most
important design goals, the Alessi inverter series is developed to serve you with safe and trouble free
operation for years.
Your Alessi inverter features an advanced micro processor control system with a MOSFET power
stage and a low loss toroidal transformer. This toroidal transformer in combination with well over
dimensioned power components, ensures a very reliable operation, so that extreme overload
conditions, like startup of compressors or pumps, can be handled safely.
To get optimal feedback from your inverter while operating, a build in diagnosis system will warn you
optically by different blinking sequences, depending on the error situation. See the troubleshooting
chapter for the blinking sequence table. Also, the inverter will warn you acoustically before it’s going to
shut down in a bad battery, overload or high temperature condition. A bi-directional communication
port is available too, for future options like a remote panel or connection to a network of power
systems equipment.
To get optimal performance and safe operation from your inverter, it must be installed and used
properly. Please read this manual very carefully, especially the warning and caution statements,
before installing and using your Alessi inverter.
2. INSTALLATION
2.1 Placement of the inverter
1. Ceiling mounting : Only recommended when ceiling is fixed and not
removable
2. Floor mounting : OK
3. Vertical wall mounting, fan at bottom : OK (beware of small objects falling through the
ventilation openings on top)
4. Vertical wall mounting, fan on top : Not recommended (reduces inverter capacity due to
insufficient cooling)
5. Horizontal wall mounting : OK
For best operating results, the inverter should be placed on a flat surface. To ensure a trouble free
operation of the inverter, it must be used in locations that meet the following requirements :
a. Avoid any contact with water on the inverter. Do not expose the inverter to rain or moisture.
b. Do not place the unit in direct sunlight or other high temperature environments. Ambient air
temperature should be between 0 °C and 40 °C (humidity < 95% non condensing). Note that in
some extreme situations the inverter’s case temperature can exceed 70 °C.

c. Do not obstruct the airflow around the inverter. Leave at least 10 centimeters clearance around
the inverter. Do not place items on or over the inverter while it’s operating. When the inverter is
running too hot, it will shut down until a safe temperature level is reached to restart the inverter.
d. Never use the inverter at locations where there is gas or explosion danger, like for example
directly on top of batteries, or in the neighbourhood of volatile liquids.
e. Do not expose the inverter to dusty environments
2.2 Using the "Remote On/Off" function
This Alessi inverter offers the possibility to connect an external (remote-) on/off SPST switch (min.
60VDC/1A). The two wires of the external switch must be connected to the terminals blocks as
indicated below. Before connecting an external switch, the factory installed link wire must be
removed first. Make sure that when installing the remote switch, the battery is NOT connected yet!
The main on/off switch on the inverter frontpanel always overrides the remote on/off switch. So in
order to use the remote switch, the main on/off switch must be in the ON or Automatic standby
(ASB) position. Maximum recommended length of the remote switch wires are 50 meters. Use
good and professional wiring for these connections to avoid easy wire damage. The recommended
wire gauge is 0.2mm2(AWG24) or greater.

2.3 The ground terminal
In order to complete the grounding circuit of your AC system, the inverter’s housing must be
connected to ground (chassis) by using the dedicated ground screw. See the figure below for the
location of the ground screw. Use a wire gauge of at least 2.5mm2(AWG13) for the ground wire.
2.4 Battery requirements
Parameter AL1000i-12 AL1400i-24 AL1500i-48
recommended input voltage range 11-14.4VDC 22-29VDC 42-58VDC
minimum recommended battery capacity1) 300Ah 180Ah 120Ah
DC input current at Pnom 88A 48A 23A
1) this capacity can be halved for short time inverter usage, not requiring more than nominal output power
The inverter shuts down when the battery voltage is below approx. 10.5V (21V for 1400i-24 and
41V for the 1500i-48) and above approx. 16V (31V for 1400i-24 and 60V for the 1500i-48). When
the battery voltage is too low or too high, first the inverter will generate one beep per second to
inform you about a possible inverter shut down. This acoustical message will start at a battery
voltage which is close to the shutdown voltage.
The inverter also shuts down when a too high input ripple voltage is detected, reducing the
inverter’s lifetime. High input ripple voltage values, are mostly caused by using too small batteries
and/or extending the DC cables too much or with an insufficient wire gauge. When the inverter
shuts down due to a too high input ripple voltage, indicated by four blinks per second, it must be
restarted manually.
CAUTION
THE ALESSI 1000i-12 MUST BE CONNECTED ONLY TO A 12V BATTERY
SYSTEM.
The inverter will not operate from a 6V battery and will be damaged when
connected to battery voltages higher than 16V.
THE ALESSI 1400i-24 MUST BE CONNECTED ONLY TO A 24V BATTERY
SYSTEM.
The inverter will not operate from a 12V battery and will be damaged when
connected to battery voltages higher than 31V.
THE ALESSI 1500i-48 MUST BE CONNECTED ONLY TO A 48V BATTERY
SYSTEM.
The inverter will not operate from lower battery voltages than 41V and will be
damaged when connected to battery voltages higher than 62V.

2.4.1 Using power supplies instead of batteries
It is not recommended to power the inverter directly from a DC power supply when full inverter
performance is required. Most power supplies are not able to supply the huge surge currents
required by the inverter, and are usually generating a too high ripple voltage causing the inverter‘s
high ripple protection to trip.
2.5 Connection to the battery
This inverter is equipped with two 25 mm² wires with a length of 1.5 meters. Unless it is absolutely
necessary, Alessi Center advises not to extend the battery wires. Extending the battery wires may
increase system losses and can cause inverter malfunctioning like tripping the input ripple
protection circuit. If it is unavoidable to extend these wires, use a wire gauge of at least 1.5 times
larger than the ones supplied with the inverter. Maximum recommended battery wire length is
approx. 3 meters. Make sure that an eventual joint between the original wires and the extension
wires is made solid and with very low electrical resistance in mind.
CAUTION
TO AVOID FIRE HAZARDS CAUSED BY DAMAGED DC WIRES, ALWAYS
PLACE A BATTERY SYSTEM FUSE AS CLOSE AS POSSIBLE TO YOUR
BATTERY TERMINALS.
Recommended battery fuse size is : 150A..200A for the 12V systems,
125A..150A for the 24V systems and 60A..100A for the 48V systems.
CAUTION
THE RED WIRE MUST BE CONNECTED TO THE POSITIVE (+) TERMINAL
AND THE BLACK WIRE TO THE NEGATIVE (-) TERMINAL OF THE
BATTERY.
Reverse polarity connection of the battery wires can damage the inverter!
Damage caused by reversed polarity is not covered by the warranty. Make sure
the powerswitch is in the OFF ‘0’ position before connecting the battery.
WARNING
IF THE INVERTER IS CONNECTED TO THE BATTERY WITH INCORRECT
POLARITY, THE DC FUSE WILL BLOW.
To replace the internal DC fuse, see chapter 5.2 for further information. If the
fuse blows again, even with the correct polarity applied, the inverter is damaged
and must be returned for service.
2.5.1 General precautions about working with batteries
1. Working in vicinity of a lead acid battery is dangerous. Batteries can generate explosive
gases during operation. Never smoke or allow a spark or flame in vicinity of a battery.
Provide sufficient ventilation around the battery.
2. Wear eye and clothing protection. Avoid touching eyes while working near batteries.
Wash your hands when done.
3. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid
enters eye, immediately flood eye with running cold water for at least 15 minutes and get
medical attention immediately.

4. Be careful when using metal tools in vicinity of batteries. Dropping a metal tool onto a
battery might cause a shorted battery and an explosion.
5. Remove personal metal items such as rings, bracelets, necklaces, and watches when
working with a battery. A battery can produce a short-circuit current high enough to weld
a ring or the like to metal, causing severe burns.
2.6 The serial communication port
This inverter is equipped with an RS485 serial communications port for future use. This port can be
used to communicate with an optional remote control panel or for connection to a TBS-Link
compatible data network. The communication port wiring is designed to work with a standard RJ45
terminated Ethernet compatible patch cable. Maximum recommended cable length is approx. 50
meters (166 feet).
WARNING
DO NOT CONNECT THE INVERTER’S SERIAL COMMUNICATION PORT TO
AN ETHERNET NETWORK OR TO ANY OTHER NON TBS-LINK
COMPATIBLE NETWORKS.
2.7 Connecting the load
Before you connect your appliance(s) to the inverter output, always check it’s maximum power
consumption. Do not connect appliances to the inverter needing more than the nominal power
rating of the inverter continuously. Some appliances like motors or pumps, are drawing large inrush
currents during startup. In these kind of situations, it is possible that the startup current is
exceeding the overcurrent trip level of the inverter. In this case the output voltage will shortly
decrease to limit the output current of the inverter. If this overcurrent trip level is continuously
exceeded, the inverter will shut down and restart within 18 seconds. In this case it is advisable to
disconnect this appliance from the inverter, since it requires to much power to be driven by this
inverter. Note that at higher ambient temperature levels, the overload capacity of the inverter is
reducing.
Besides indicating the type of error, the red LED on the inverter also functions as an overload
indicator. When heavy loads are switched on, this LED will shortly be activated due to the inrush
current of the load. If the ERROR/OVERLOAD LED stays on for 6 seconds, the inverter will shut
down and jumps into the overload error mode (see chapter 3.1)
CAUTION
NEVER CONNECT THE INVERTER’S OUTPUT TO THE AC DISTRIBUTION
GRID, LIKE YOUR HOUSEHOLD AC WALL OUTLET. IT WILL DAMAGE THE
INVERTER.

WARNING
WHEN CONNECTING MORE THAN ONE APPLIANCE TO THE INVERTER,
IN COMBINATION WITH A COMPUTER, NOTE THAT IF ONE OF THE
APPLIANCES IS STARTING UP, IT CAN CAUSE YOUR COMPUTER TO
REBOOT DUE TO A SUDDEN VOLTAGE DROP.
2.8 Turning on the inverter
When all the above requirements are checked and satisfied and all connections are made, it’s
time to turn on your Alessi inverter by pushing the power switch in the ‘ I ’ position. After a short
two tone beep, the sinewave shaped output voltage is gently rising until 230V/50Hz ±1% (or
115V/60Hz ±1%) is reached, ready to power your appliances.
When the inverter is not supplying power to an appliance for a longer time, it is recommended to
use the inverter in Automatic Standby (ASB) mode to heavily reduce the inverter’s own power
draw. In this case the power switch must be pushed in the ' II ‘ position. In ASB mode the inverter
will generate a testpulse on it's output once per second, to check when there is a load applied.
When the ASB mode is activated (by generating a reversed two tone beep), the blue AC Present
LED will flash continuously for 4 seconds while the inverter outputs a continuous 230V (or 115V)
sinewave. After this 4 seconds the continuous output will change to a pulsed output. Every time this
pulse is generated the blue LED is activated too, in order to indicate that there’s a lethal AC voltage
present at the output. When a load is connected to the inverter output (or switched on) drawing
more than approx. 5W, the inverter jumps to the continuous mode immediately, delivering power
to the load. When the load is disconnected again (or switched off) the blue LED starts flashing for 4
seconds and the inverter jumps back to the pulsed output ASB mode. This way the inverter
automatically jumps to a low power 'sleep' mode when there is no power demand on the output.
Note that some loads like TV/video equipment (with standby mode) and alarm clocks need
continuous power so that the ASB mode can not be used.
With some small non compensated loads, it is possible that the inverter jumps from continuous
output to pulsed output and vice versa all the time. In this case you have to connect a small
additional load to the AC output.
WARNING
IF THE INVERTER JUMPED INTO AN ‘ERROR MODE’ (SEE CHAPTER 3.1)
DUE TO AN OVERLOAD OR SHORT CIRCUIT, THE INVERTER WILL
AUTOMATICALLY RESTART AFTER ABOUT 18 SECONDS.
In case of a high temperature error, the inverter will automatically restart after it
has reached an acceptable temperature. Right before the inverter will restart, it
will warn you with a short beep.
NEVER SERVICE THE AC CONNECTIONS WHEN THE INVERTER IS STILL
RUNNING IN AN ERROR MODE!
WARNING
THE BUILD IN LARGE ELECTROLYTIC CAPACITORS CAN HOLD
SIGNIFICANT DC VOLTAGE WHEN THE BATTERIES ARE
DISCONNECTED.
To avoid sparks or short inverter operation, it is advisable to switch on the
inverter for 10 seconds after battery disconnection, before you transport the
inverter.

3. SELF DIAGNOSIS SYSTEM / TROUBLESHOOTING
3.1 The blink sequence table
This Alessi inverter is equipped with a self diagnosis system, to inform you about the cause of
inverter shut down. To visualize this, the red Error/Overload LED can blink in four different
sequences. The duration, or timeperiod, of this sequence is about 1 second. During this timeperiod
the red LED can blink four times in a row at most. The number of blinks in this time period indicates
the cause of inverter shut down.
In the table below you can find out what kind of blinking sequence belongs to which error.
Red LED conditions :
}= LED blinking
z=LEDON
{= LED OFF
Time period (1 second) Type of error
}{{{ Battery voltage too low or too high
(one blink per second)
}}{{ Overloaded or shorted output
(two blinks per second)
}}}{ Inverter temperature too high. Cooling down
(three blinks per second)
}}}} Too high input ripple voltage
(four blinks per second)
z→Overload, output in current limit
WARNING
IN A 'BATTERY VOLTAGE TOO LOW OR TOO HIGH' ERROR, THE
INVERTER WILL AUTOMATICALLY RESTART WHEN THE BATTERY
VOLTAGE IS IN NORMAL SPECIFIED RANGE AGAIN.
IN AN 'OVERLOADED OR SHORTED OUTPUT' ERROR, THE INVERTER
WILL AUTOMATICALLY RESTART AFTER APPROX. 18 SECONDS
IN AN 'INVERTER TEMPERATURE TOO HIGH' ERROR, THE INVERTER
WILL AUTOMATICALLY RESTART WHEN THE TEMPERATURE HAS
FALLEN TO AN ACCEPTABLE LEVEL AGAIN.
IN A 'TOO HIGH INPUT RIPPLE VOLTAGE' ERROR, THE INVERTER WILL
NOT AUTOMATICALLY RESTART BUT NEEDS TO BE RESETTED
MANUALLY. Manual reset is necessary to notify the user that something is
wrong with the inverter's installation (too small battery, too long or thin DC wires
etc.)
3.2 Acoustical messages
To warn you before the inverter might shut down, it is equipped with an acoustical alarm. This can
be very useful when you are for example working with a computer which runs from the inverter.
The inverter can alarm you right before it is going to shut down, so you can save or finish your work
before you lose power.
There are three kinds of acoustical messages depending on the cause of possible inverter
shutdown. These messages are related to the red LED blinking sequences mentioned previously.

The Alessi-Serie
Pure Sine Wave Inverters
- 11 -
Message 1: One beep per second. The battery voltage has reached a too low or too high
level. If the battery voltage respectively decreases or increases any further, the
inverter shuts down.
Message 2: Two beeps per second. The inverter will shut down soon due to an
overloaded output. Note that at heavy overloads the alarm will not sound due to
too fast inverter shut down. Normally the inverter warns approx. 10 seconds before
shutdown.
Message 3: Three beeps per second. The inverter will shut down when it’s temperature is
rising another two degrees Celsius.
3.3 Troubleshooting guideline
PROBLEM :Inverter is not working (AC Present LED OFF)
Possible cause : Remedy :
Power switch in OFF (0) position Push the power switch either in the ON (I) or in
the ASB (II) position.
Poor contact between the inverter’s battery
wires and the battery terminals.
Clean battery terminals or inverter wire
contacts. Tighten battery terminal screws.
Blown inverter fuse Replace damaged fuse with the correct type.
Make sure you disconnect the battery before
changing the fuse. See chapter 5.2 for further
information regarding fuse replacement.
Very poor battery condition Replace battery or charge it first
Remote ON/OFF switch link removed and/or
remote switch in OFF position
Make sure that there is a closed circuit between
the two Remote ON/OFF switch contacts to
start the inverter.
PROBLEM :‘Battery voltage too low or too high’ error keeps on appearing
Possible cause : Remedy :
Poor battery condition Replace battery or charge it first
Poor connection or inadequate wiring between
battery and inverter, resulting in too much
voltage drop
When extending the battery wires of the inverter
make sure you use the correct wire gauge (≥
1.5 times larger than the fixed battery wires). It’s
not advisable to extend the battery wires to
more than 3 meters.
General failure in your electrical system (in case
of no direct battery connection)
Check your electrical system or consult an
electrical engineer to check it for you
PROBLEM :‘Overloaded or shorted output’ error keeps on appearing
Possible cause : Remedy :
Inverter is overloaded Make sure that the total power rating of the
connected equipment is lower than the nominal
inverter power rating.
Connected equipment features a bad power
factor (cosϕat sinusoidal currents)
reduce the required power consumption of the
load. Please note that for example a computer
load features a bad power factor, which causes
a reduction of the maximum output power of the
inverter by approx. 20%.
Connected equipment causes a short circuit at Make sure that the connected equipment is not

The Alessi-Serie
Pure Sine Wave Inverters

the inverter’s output broken or malfunctioning. Check if the AC
power cord between the inverter and the
connected equipment is ok. Any physical
damage on the power cord can produce a short
circuit. Be careful in these kind of situations!
Connected equipment produces a too large
inrush current
(The red Error/Overload LED stays on at load
startup)
Try to power-up connected equipment
successively, and not simultaneously. Or
connect the load first and then turn-on the
inverter. Otherwise stop using the connected
load, it’s not suitable to drive it with this inverter
PROBLEM :‘Inverter temperature too high. Cooling down’ error keeps on appearing
Possible cause : Remedy :
Airflow around the inverter is obstructed Make sure there is at least 10 centimeters of
clearance around the inverter. Remove any
items placed on or over the inverter. Keep the
inverter away from direct sunlight or heat
producing equipment
Too high ambient temperature Move the inverter to a cooler place or provide
additional cooling by an external fan
Note : Don’t turn off the inverter when it’s operating in an ‘Inverter temperature too high. Cooling
down’ error. The inverter needs this error time to cool down.
PROBLEM :‘Too high input ripple voltage’ error keeps on appearing
Possible cause : Remedy :
Input voltage ripple is too large caused by poor
inverter installation
Reduce load, enlarge battery capacity, make
sure the DC wires are not extended too long (<3
meters) and that sufficient wire gauge is used
(>1.5x the standard equipped wire gauge),
check eventual generators/dynamos/high ripple
chargers which are connected to the same DC
system.
PROBLEM :Inverter jumps between continuous mode and pulsed ASB mode all the time
Possible cause : Remedy :
Connected load is not compensated or the ratio
between inrush current and continuous current
is too large.
Connect an additional load to the output.
If none of the above remedies will help solving the problem you encounter, it’s best to contact your
local Alessi Center distributor for further help and/or possible repair of your inverter. Do not try to
repair the inverter yourselves, there are dangerous high voltages present inside. Attempts to repair
and/or modify the inverter will directly void your warranty period.
4. WARRANTY
Alessi Center warrants this inverter to be free from defects in workmanship or materials for 24
months from the date of purchase. During this period Alessi Center will repair the defective
inverter free of charge. Alessi Center is not responsible for any costs of the transport of this

inverter.
This warranty is void if the inverter has suffered any physical damage or alteration, either internally
or externally, and does not cover damage arising from improper use, attempting to operate the
inverter with excessive power consumption requirements, or from use in an unsuitable
environment.
This warranty will not apply where the product has been misused, neglected, improperly installed
or repaired by anyone other than Alessi Center. Alessi Center is not responsible for any loss,
damage or costs arising from improper use, use in an unsuitable environment, improper installing
of the inverter and inverter malfunctioning.
5. MAINTENANCE / FUSE REPLACEMENT
5.1 Maintenance
Your Alessi inverter does not need any specific maintenance besides checking all DC and AC
connections at least once a year. Check if all nuts and bolds in the electrical system are still
tightened sufficiently and if all cables are in good condition. Keep the inverter reasonably clean and
remove eventual dust/cloth gathered at the fan in- and outlets to avoid extra airflow obstruction.
5.2 Replacing fuses
The inverter is equipped with two internal fuses, one on the DC side and one on the AC side.
These fuses will only blow in case of serious malfunction and/or external inverter abuse like
reverse polarity of battery connections. Both fuses can be accessed by removing the hood of the
enclosure as described below.
CAUTION
BEFORE OPENING THE INVERTER TO REPLACE A FUSE, ALWAYS
DISCONNECT THE BATTERY FROM THE INVERTER FOLLOWED BY
DISCHARGING THE INTERNAL CAPACITORS BY PUSHING THE POWER
SWITCH (OF THE DISCONNECTED INVERTER) IN THE 'I' POSITION FOR 10
SECONDS.
1. Unscrew the 8 top hood screws (4 on each side, see picture below) to lift the top hood, enabling
access to the internal fuses. To make removing the top hood easier, it is advisable to slightly
unscrew the remaining left- and right screws on one side of the inverter.
Remove these four screws on both
sides of the inverter enclosure
Gently lift the hood upwards

3. The AC side fuse can be replaced by turning and pushing the plastic cap counter clockwise until
the cap releases and can be pulled out. The DC fuse can be replaced by unscrewing the two
nuts. Make sure the new fuse is inserted in exactly the same position as the previous one (see
picture below). Apply sufficient torque to the nuts so that the spring washers are maximally
crushed, but avoid bending the main PCB.
4. Place the hood carefully back again, without hitting the internal DC fuse and/or frontpanel
printed circuit board. Put all eight screws including the spring washers back in place. Do not
forget to fasten any other screws which were needed to simplify top hood removal. Now you
can reinstall your inverter. If the replaced fuse blows again while the inverter is installed
correctly, the unit must be returned for service to your local distributor.

1. INTRODUCTIE
De Alessi sinus omvormers staan bekend als één van de meest geavanceerde op dit moment
verkrijgbare omvormers. Met een hoge betrouwbaarheid, rendement en sinus kwaliteit als één van de
meest belangrijke ontwerp eisen, zijn de Alessi omvormers ontwikkelt om u te voorzien van een jaren
lange veilige en probleemloze werking.
Uw Alessi omvormer maakt gebruik van een geavanceerd microprocessor besturingssysteem en een
MOSFET power stage met een zeer efficiënte ringkern transformator. Met deze speciale transformator
in combinatie met ruim overgedimensioneerde vermogens halfgeleiders, wordt een zeer betrouwbare
werking gegarandeerd. Hierdoor kunnen extreme overbelastingen, zoals het opstarten van
compressors of pompen, veilig worden doorstaan.
Om volledig op de hoogte te kunnen blijven van de status van uw omvormer, is een diagnose systeem
ingebouwd om u te waarschuwen in het geval van alarm situaties. Aan de hand van het knipper
patroon van de rode LED kan bepaald worden met welk type alarm u te maken heeft. Daarnaast kan
de Alessi omvormer u ook akoestisch waarschuwen voordat de omvormer uitschakelt vanwege een te
lage accuspanning, een overbelastingsconditie of een te hoge temperatuur. Een bidirectionele
communicatie poort is voorhanden voor toekomstige opties zoals een afstandsbediening of voor
aansluiting op een computer netwerk van energie systemen.
Om een optimale en veilige werking van uw omvormer te verkrijgen is het belangrijk dat deze op de
juiste manier geïnstalleerd en gebruikt wordt. Lees daarom eerst zorgvuldig deze gebruiksaanwijzing
voordat u met uw Alessi omvormer aan de slag gaat.
2. INSTALLATIE
2.1 Plaatsing van de omvormer
1. Plafond montage : Alleen aanbevolen wanneer het een vast
plafond betreft die niet verwijderbaar is.
2. Vloer montage : OK
3. Verticale muur montage, ventilator onder : OK (pas op kleine objecten die door de
ventilatie openingen aan de bovenkant kunnen
vallen)
4. Verticale muur montage, ventilator boven : Niet aanbevolen (reduceert de omvormer
capaciteit)
5. Horizontale muur montage : OK
Om een probleemloze werking van de omvormer te kunnen garanderen, moet de lokatie waarin
deze wordt geïnstalleerd aan de volgende eisen voldoen :
a. Vermijd elk contact tussen water en de omvormer. Stel de omvormer niet bloot aan regen of
mist.
b. Plaats de omvormer niet in direct zonlicht of andere hoge temperatuur omgevingen. De

omgevingstemperatuur moet tussen 0 °C en 40 °C liggen (luchtvochtigheid < 95% niet
condenserend). In sommige extreme situaties kan de behuizing van de omvormer een
temperatuur bereiken van meer dan 70 °C.
c. Vermijd obstructie van de luchtstroming rond de omvormer. Laat minstens 10 centimeter adem
ruimte vrij rond omvormer. Plaats geen voorwerpen op of over de omvormer wanneer deze
aktief is. Wanneer de omvormer een te hoge temperatuur heeft bereikt, zal deze zichzelf
uitschakelen totdat de omvormer is afgekoeld tot een acceptabele temperatuur.
d. Gebruik de omvormer nooit in plaatsen waar gas of explosie gevaar aanwezig is, zoals
bijvoorbeeld direct op de accu’s of in de buurt van vluchtige stoffen.
e. Stel de omvormer niet bloot aan stoffige omgevingen.
2.2 De "Remote On/Off" functie
Deze Alessi omvormer biedt de mogelijkheid een externe aan/uit schakelaar (min. 60VDC/1A)
aan te sluiten. De twee draden van de externe schakelaar moeten aangesloten worden op de
klemmenstroken zoals hieronder is aangegeven. Voordat u de externe schakelaar aansluit, moet
eerst de af-fabriek geplaatste doorverbinding verwijderd worden. Let op dat bij het installeren van
de externe aan/uit schakelaar, de accu nog NIET aangesloten is!
De hoofd aan/uit schakelaar op de omvormer zelf, zal altijd de omvormer kunnen uitschakelen
ongeacht de stand van de externe schakelaar. De hoofd aan/uit schakelaar moet altijd in de stand
'POWER ON' of 'AUTOMATIC STANDBY' staan om de externe schakelaar te kunnen gebruiken.
Maximaal geadviseerde lengte van de externe schakelaar draden is ca. 50 meter. Gebruik
bedrading van een goede kwaliteit om gemakkelijke beschadiging van de isolatie te voorkomen. De
aanbevolen draadoppervlakte is 0.2mm2of groter.
