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 
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
Control
The tension of the batteries is submitted to control. During their use, the tension must be between the following ranges :
11.4V and 16 V in the 12 Volt models,
22.8V and 32 V in the 24 Volt models,
45.6V 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.
Internal fuse
Fuse | Inverter SI (mod.) | |
40A | 648 |
|
50A | 624 | - 1248 |
60A | 824 | – 1448 |
80A | 612 | – 2348 - 2360 |
100A | 812 | – 1224 – 3548 - 3060 |
2*100A | 1212 – 1624 – 2324 | |
2*125A | 3324 | |
The use of higher fuse value will not improve the performance of the inverter and will degrade safety protection !
