4.3.3 Connecting the battery voltage sensor
NOTICE!
The external battery voltage sensor cable allows the controller to directly measure the voltage
at the battery. This voltage value can be used for compensation of voltage drops across the
battery cables. This means that the voltage measurement is not affected by (e.g.) power-
dependent voltage drops across the battery cables.
-
A 2-pin plug with screw terminals for connecting the sensor cable is supplied with the device.
A cable with a cross-section of 0.14-1.5 mm
2
(AWG 28-16) can be used.
-
The necessary sensor cable is not supplied with the device.
A sufficiently long battery voltage sensor cable conforming to the technical data is available.
DANGER!
Install a fuse in the connection between the battery voltage sensor cable and the battery. The
fuse rating must match the cross-section of the cable used. This protects the cable from
burning in the case of a short-circuit in the battery voltage sensor cable.
1. Fit the green 2-pin socket (supplied) to the other end of the cable.
2. Plug the 2-pin socket into the"BAT+/–" connection so that the "+" conductor is at the left and
the "" conductor is at the right; see the enlarged view of the terminal area in
Fig. 2.
3. Install an external fuse for protecting the battery voltage sensor cable.
4. Connect the battery voltage sensor cable directly to the battery; see in Fig. 2.
5. Activate usage of the battery voltage sensor cable in the cable compensation settings.

4.3.4 Connect the ground (PE)
DANGER!
Risk of death by electrocution. The controller must be grounded via PE (controller has
protection class I).
