Select the battery capacity with the BMU801
rotary switch according to the battery in your system. BMU801 automatically detects if there
are 1 or 2 batteries connected. The connected batteries should have the same capacity. This
means that even if there are 2 batteries, you only need to select the capacity once.
The default switch position set at the factory is 4 (26 Ah battery).
CAUTION Make sure that you select
the same capacity as the battery in your system has. Incorrect selection can cause damage to
the battery and prevent or limit operation.
If BMU801 is preinstalled in
your system, the battery capacity is typically selected already at the factory.
Using a flat head screwdriver (max. 2.5 mm), turn the rotary switch until the arrow
points to the desired position.
If you find it difficult to operate the rotary switch while BMU801 is
mounted on a DIN rail with other components close to it, remove BMU801 from the DIN
rail.
