Version 01.20 // 2021
NOTE!
The power supply is looped through from the
IN
socket to the
OUT
socket.
Thus, a signal at a specific pin of the
IN
socket is always available at the
OUT
socket, too.

4.4.2.4 Ground connection
The HV BM has to be connected to ground in order to ensure user safety. The cross section
of a ground cable depends on the cross section of the HV power cable used.
WARNING!
To ensure user safety, the measurement module must be connected to
vehicle ground (leakage monitor) or protective ground (PA/PE).
If the ground connection is not established, there is danger to life due to
high voltage.
"
Connect the measurement module to ground (PE) using a suitable
ground cable.
"
Make sure that this work is only carried out by qualified and trained
personnel.
NOTE!
i
The threaded hole (M6 or M8, depending on the hardware revision) in the
right (HV BM 1.x) or the left (HV BM 3.1) section of the housing has been
designed to connect the housing to the vehicle ground or to the protec-
tive ground (PA/PE) in the test bench.
"
Don’t use the threaded mounting hole for any other purpose, e.g. for
mounting the device.
14 "xxxxx" is a placeholder here. The actual designation depends on the diameter of the cable used.
