4 3 2 2 8-pin LEMO Redel multi connector
The HV DTemp-P central unit is equipped with two 8-pin multi-connector sockets. Depending on
the license, a maximum of eight controllers can be connected to the two measuring inputs. The
controllers can be distributed to both measuring inputs or connected to only to one of them.
4 3 2 3 Ground connection
The housing of an HV DTemp-P central unit can be connected to ground as an additional
safety measure in order to have the device controlled by the leakage monitor. For this
purpose the measurement module is equipped with a threaded hole in the top side of front
bracket. This threaded hole must only be used for this purpose.
NOTE!
i
The M6 threaded mounting hole is designed to connect the device housing
to the vehicle chassis or to protective ground in a laboratory, if necessary.
Do not use the M6 threaded mounting hole for any other purpose
than connecting the device housing to ground.
