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.
Any modifications to the product or its components are prohibited
and do not conform to its intended use. Only use original LEAB or
LEAB-approved 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 se-
lect a sufficient cable cross-section for connecting the device.
WARNING!Risk of injury from electric shock: Disconnect the
battery negative lead prior to assembly/disassembly.
NOTE!Incorrect usage can damage the device: Only use the
device within the specified operating parameters.
NOTE!Install the device in a dry and cool location.
NOTE!Residual voltage can cause damage: Do not place the pos-
itive lead on the vehicle bodywork.

To install the device, proceed as follows:
1. Disconnect the battery from the vehicle power circuit.
WARNING!Disconnect the negative cable first.
2. Set the desired switch-off voltage on the DIP switches (10).
3. Connect an earth wire from the battery monitor’s ground (6) con-
nector to the battery's negative terminal.
NOTE!Only the switching current (1 A) is permissible. The con-
sumer load must not lead via the 'ground’ connector (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.
Optional connections
– Connect an external buzzer via the ‘alarm output’ connector
(5). NOTE!Contact to ground, max. 1 A.
– Use the battery monitor as a main switch for connected con-
sumers by running a line with a switch between the negative
terminal of the battery and the connector for “external
switch” (4).
– Connect the 3-colour LED by connecting the anode for green
(shortest leg) to the “Green” LED connector (7), the cathode
(longest leg) to the LED connector (8) and the anode for red to
the “Red” LED connector (9).

Internal buzzer beeps at
interval*
Safety level 1: Below alarm threshold.
Battery voltage will soon reach the
switch-off voltage.
1. Switch the consumers off or charge
the battery
LED flashes red
Alarm output inactive
Internal buzzer beeps 1x
Safety level 2: Below switch-off
voltage. Consumers have been discon-
nected from the battery to avoid deep
discharge.
2. To supply consumers again, charge
the battery to the switch-on voltage.
LED no colour Device is switched off or incorrectly in-
stalled.
* Internal buzzer interval: 600s – 300s – 150s – 75s – 37s – 18s
– 9s.
After that: Internal buzzer beeps every 9 seconds until the switch-
off voltage is reached.
NOTE!The operating status of the device is shown by the operat-
ing display (3), the 3-colour LED, the alarm output (5) and the in-
ternal buzzer.
Decommissioning
To decommission the device, proceed as follows:
1. Disconnect the battery from the vehicle power circuit.
WARNING!Disconnect the negative cable first.
2. Remove the leads on the connectors (1), (2), (4), (5) and (6)
from the vehicle.
ðThe device is decommissioned.
Disposal
Dispose of the device in accordance with the Waste
Electrical and Electronic Equipment Regulations
(WEEE).
The system must not be disposed of with household
waste. Take it to a recycling point or return it to your
point of sale.
