HV Breakout Module – Mounting and installation
Installation Manual

Version 01.20 // 2021
4.4.2 Connectors
An HV Breakout Module is equipped with a CAN and an EtherCAT® interface. The corresponding
sockets are embedded in the left (HV BM 1.x) or right (HV BM 3.1) side of the housing. The
HV power cables are led through PG glands into the inside of the module and connected there.
For safety reasons, the measurement module must be connected to the vehicle ground or to
the protective ground (PA/PE ) in the test stand via the threaded hole in the right (HV BM 1.x)
or left (HV BM 3.1) side of the module.
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 measurement module’s power supply can be provided either via CAN
or EtherCAT® socket. The supply lines of the two CAN sockets are connec-
ted to each other. The same applies to the two EtherCAT® sockets. The CAN
and EtherCAT® interfaces are nevertheless separated from each other.
This means that the supply voltage fed to CAN is not provided at the
EtherCAT® sockets and vice versa. Banana plugs which are not in use do
not need to be isolated.
4.4.2.1 CAN sockets
The CAN connectors can be used for both CAN signals and power supply. The interface cable
connects the measurement module to the data acquisition system (PC or data logger) and
(if required) to the power supply.
NOTE!
i
Be particularly careful when connecting third-party devices to a measu-
rement bus with HV Breakout Module devices.
"
Make sure that the configuration settings are compatible with all
devices (same CAN bit rate, different CAN identifiers).

Make sure that this work is only carried out by qualified and trained
personnel.
CSM uses LEMO 0B sockets as standard for the CAN sockets. To connect a cable to this socket,
the following plug with plug insert is required:
