After 8 h float charging, the battery charger automatically switches to the master or normal mode. If the battery
charger communication is activated again, the battery charger switches to slave mode after 10 s. The battery charger
uses the last configuration saved for the battery.
If the batteries are fully charged, the 25 A supplied by the battery charger can be used to supply power to the vehi-
cle interior.
The battery charger is equipped with an AC interlock socket. When the battery charger is connected to an AC
source, an internal relay of the battery charger short-circuits the AC interlock socket, which connects the battery
charger to the vehicle's starting circuit to prevent the vehicle from starting.
The battery charger is equipped with a jump starter button that allows charging of the starting battery using the
house battery.
The battery charger has the following protective systems:
• Overvoltage protection
• Overheating protection
• Overload protection
• Short circuit protection
• Output polarity protection
