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 preventing
deep discharge for batteries with a nominal voltage of 12 V or 24 V.
Audible and visual alarms warn you of an approaching deep discharge. If
power continues to be removed from the battery, the battery monitor dis-
connects consumers from the battery to prevent deep discharge. The
threshold values for the alarm and for switching off the consumers are
set via DIP switches.
Any modifications to the product or its components are prohibited and
do not conform to its intended use. Only use original LEAB or LEAB-ap-
proved accessories.
Observe the safety instructions:
WARNING! Incorrect assembly or inadequate wiring can cause a
fire: Only install the unit as described in these instructions and select a
sufficient cable cross-section for connecting the device.
WARNING! Risk of injury from electric shock: Disconnect the bat-
tery negative lead prior to assembly/disassembly.
