Installation type 2 – Battery separator relay already present
The BCB is installed in parallel to an already installed battery.
Remarks:
• Installation in a strategically favorable place behind the originally existing battery separator relay.
Use booster cable set MT 93045 optionally!
• Controlling of the originally existing battery separator relay and the BCB takes place simultane-
ously with the D + signal and the BCB takes over the charging management of the board battery.
When connected to the mains, only the board battery will being charged! The starter battery
cannot be maintained when the battery separator relay is open.
• Please check whether the originally present cable cross-sections and fuses are adequately
dimensioned (according table 1). If this is not the case and when using the BCB 40/40 and BCB
60/40, the maximum power consumption must be limited with the “Limit Boo” switch (position
to the left). This ensures that originally present cabling, fuses and the battery separator relay –
depending on the version – are not overloaded when driving
