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
To use the battery monitor as a main switch for the connected consumers,

the battery
LED flashes red
Alarm output inactive
Internal buzzer beeps 1x
Safety level 2: Below switch-off voltage.
Consumers have been disconnected
from the battery to avoid deep dis-
charge.
2 To supply consumers again, charge
the battery to the switch-on
voltage.

After that: Internal buzzer beeps every 9 seconds until the switch-off voltage is
reached.
9 Decommissioning
WARNING
Risk of injury from electric shock
