General Safety
This guide supports safe handling of the product. Use the product
only in accordance with its intended use:
The BW 801e battery monitor is a two-stage safety system for pre-
venting deep discharge for batteries with a nominal voltage of 12 V
or 24 V.
Audible and visual alarms warn you of an approaching deep dis-
charge. If power continues to be removed from the battery, the bat-
tery monitor disconnects consumers from the battery to prevent
deep discharge. The threshold values for the alarm and for switch-
ing off the consumers are set via DIP switches.
