Carefully move the 

2 micro slide switches 

on the side of the unit to the 

desired position using a small screw-driver.

How to Set the Charging Program Battery Type "BOARD"- (Design, 
Technology): 

Four (4) charging programs

 for the different battery types are stored in the unit. 

 

They can be selected by means of the shown 

2 slide switches

Unless otherwise specified by the battery manufacturer, the appropriate charging program for 
the BOARD supply battery can be found in the following description and the technical data 
(voltage rates U1 and U2). 

All charging programs automatically take into account the possibility of parallel/buffer 
operation with 12V loads being connected to the BOARD battery.

batteries and closed, SLA, low-maintenance, 
maintenance-free "non-solid electrolyte", "lead-acid", 
traction, lighting, solar and heavy-duty batteries. Also 
suitable for recently developed batteries (low-
antimony, with silver-alloy, calcium or similar) and 
batteries with low (L) and very low (VL) water consumption.
