The battery charger provides multi-stage intelligent
charging:
– Constant current: maximum current available
during charge recovery phase
– Constant voltage
– Chargers automatically return to float mode when
charging is complete
It also offers full protection:
– Reverse polarity protection, short circuit
protection and current limiting
– Automatic recovery after the removal of fault
conditions
To use the battery charger:
– Provide connector X4 with external power:
• terminals for inlet supply: 832 - 835
• terminals for outlet: 6 - 7
9.3.2 Battery switch
The battery switch is situated inside the sound-
insulated bodywork. It allows to open or to close the
electrical connection between the battery and the
engine circuits.
9.3.3 Engine coolant heater
To make sure that the engine can start and accept load
immediately, an external cooling water heater
(1000 W, 240 V) is provided which keeps the engine
temperature between 38°C and 49°C.
9.3.4 Single phase
The single phase option provides single phase output
voltage (e.g. 230 V).
X10 .....Main power supply (230 V AC)
Terminals L1, N and PE (= earthing), hidden
behind the control panel door.
Q600 ...Circuit breaker for single phase
operation
Interrupts phases L1 and N towards X10
when a short-circuit occurs at the load side
or when the overcurrent protection (
QES 9:
32 A, QES 14: 40 A, QES 20: 63 A, QES 30:
100 A, QES 40: 125 A) is activated. It must be
reset manually after eliminating the
problem.
Never turn the battery switch to
OFF during operation.
Only available for 50 Hz units.
