Adjustments 
 (Not automatic with Twinpower version) 
Standby Level (1) 
The activation of the inverter, when working in 
automatic mode, is dictated by the detection of a 
load. With this function, it is possible to adjust 
the minimum load detected between 0,3 and 20 
Watts. This level is factory adjusted to 2 
watts and so no further adjustment will 
probably be needed. 
Adjustment procedure 
Make sure that no device is connected. 
 
Check for the presence of hidden users such as 
television, fax, video, … which often have a 
standby mode and remain working even after 
being turned off ! 
 
Put the switch in “ Autom. ” position. 
 
Introduce a screw driver N°1 delicately in the 
hole (1) provided and turn gently until you feel 
the screw driver insert in the groove of the 
screw. 
Turn clockwise 
 until tight without pressing 
(do not force!). 
 
Wait until the green LED blinks. 
 
Activate the minimum charge you wish to detect. 
Turn the screw slowly anti-clockwise 
 
without pressing until the inverter activates. 
(green LED illuminated). 
 
Check that the inverter goes back to standby 
mode a couple of seconds after deactivation of 
all charges. 
 
 Warning : In maximum anti-clockwise position 
the inverter continues to work even if there is no 
load
Control 
The tension of the batteries is submitted to 
control. During their use, the tension must be 
between the following ranges : 
 
11.4 V and 16 V in the 12 Volt models, 
22.8 V and 32 V in the 24 Volt models, 
45.6 V and 61 V in the 48 Volt models.  
 
Outside these ranges the inverter is 
automatically disconnected. 
 
These values correspond to a no load situation 
and they are automatically adjusted according to 
the current of the battery. 
 
The internal temperature and the maximum 
power are also submitted to control. 
 
In the case of prolonged overload or deficient 
ventilation it is not possible to restart the inverter 
until it has cooled down. 
Indicators 
Green Run - LED (3) 
Illuminated: the inverter is connected. A 230 V 
tension is present in the outlet. 
Blinking : (only SI version) The inverter is in 
“ Autom. ” mode and no voltage is detected by 
the standby system. 
 
 A 230 V tension is intermittently present! 
Red Fault - LED (2) 
The inverter is stopped : 
The tension of the battery is not correct 
After an overload, overheating or short circuit 
To restart the inverter after a failure, put the 
switch (4) in “ OFF ” position for 10 seconds, 
then connect again
Safety 
The inverter is internally protected against 
overloads and short circuits. Should this 
protection fail, the inverter is equipped with a 
fuse (fire protection). If the fuse is broken, 
qualified technicians should control the 
installation and change the fuse.

The use of higher fuse value will not improve the 
performance of the inverter and will degrade 
safety protection !
