5 About this Product
The BW 801e battery monitor is a two-stage safety system to avoid deep dis-
charge of your battery. Audible and visual alarms warn you of an approaching
deep discharge. If power continues to be removed from the battery, the bat-
tery monitor disconnects consumers from the battery to prevent deep dis-
charge. The threshold values for the alarm and for switching off the con-
sumers are set via DIP switches.

To install the device, proceed as follows:
1 Disconnect the battery from the vehicle power circuit.
WARNING!Disconnect the negative cable first.
Fig.2: DIP switch
2 Set the desired switch-off voltage on the DIP switches
(10).
3 Connect an earth wire from the battery monitor’s
ground (6) terminal to the battery's negative terminal.
NOTE!Only the switching current (1 A) is permissible.
The consumer load must not lead via the 'ground’ con-
nector (6).
4 Disconnect the positive lead from the battery to the
consumers and connect the battery monitor at the
screw terminals (1) and (2).
5 Connect the battery to the vehicle power circuit.
ðThe device is ready for operation. When the battery
voltage is sufficient, the operating display (3) lights
green.
7.1 Optional: connect external buzzer
To connect an external buzzer, proceed as follows:
NOTE!Contact to ground, max. 1 A.
1 Connect an external buzzer via the ‘alarm output’ connector (5).
ðAn external buzzer is connected.
7.2 Optional: Using the battery monitor as a main switch
