Note 1: Current leakage protective device
is optional. The positive, negative and
neutral battery cables should be routed
through the sensor, but the earth cable
should not be routed through the sensor.

6.10 Battery Temperature Sensor (Option)
Emerson provides an optional battery temperature sensor. Conect the battery temperature sensor as shown in
Figure 6-5.
6.11 Battery Ground Fault Detector (Option)
Emerson provides an optional battery ground fault detector. It includes a current transformer and a PCB, which
should be installed in the BCB box. The installation position of the PCB is shown in Figure 6-4. If the BCB box uses
top cable entry, the current transformer should be installed on the inside of the top plate of the BCB box, as shown in
Figure 6-4; if the BCB box uses bottom cable entry, the current transformer should be installed on the inside of the
bottom plate of the BCB box. Connect the PCB as shown in Figure 6-5.
Note
If a battery ground fault detector is installed, the positive, negative and neutral battery cables from the battery into the BCB box
must be routed through the hole of the current transformer of the battery ground fault detector, while other cables must bypass the
current transformer.
