Description of the electrical

Automatic battery charger
The automatic battery charger charges the battery
completely and is disconnected once the unit starts
up.
Besides the output terminals (secondary side) the
automatic battery charger has a trim potentiometer for
setting of the output voltage. By means of an insulated
slotted screwdriver or adjusting pin the output voltage
can be set in the range.
The LED on the front indicates that the unit is
operational.
Setting:
– Lower output voltage = counterclockwise rotation
– Higher output voltage = clockwise rotation
To use the batery charger:
– Provide the X25 connector, located at the side of
the power cubicle, with external power to use the
battery charger.
Engine coolant heater
To make sure that the engine can start and accept load
immediately, an external cooling water heater
(2000 W, 240 V) is provided which keeps the engine
temperature between 38°C and 49°C.
