6.4.8 Mounting terminating resistor of CAN bus
If you want to operate the device in parallel operation, you need to mount a
120 Ω terminating resistor at both ends of the CAN bus. Use the plug con-
nector with terminating resistor provided as an option.

WARNING
Danger of death or severe injury!
An energized transformer and energized on-load tap-changer components
could cause death or serious injuries when installing the electrics!
► Adherence to the following safety precautions is mandatory.
The drive may only be connected to circuits that are equipped with an exter-
nal and all-pole isolating device as close to the drive as possible to ensure
that the unit can be fully de-energized if required (service, maintenance etc.).
Furthermore, a drive without its own overcurrent protective device for the
control circuit and the heater circuit may only be connected to circuits that
are equipped with an external overcurrent protective device. The protective
device must ensure protection against indirect touching. The protection rec-
ommended by Maschinenfabrik Reinhausen GmbH close to the drive is 1.6
A C (3.0 A C is to be used in a heater circuit with additional heating and sup-
ply voltage <127 V AC/DC). This is to be verified after installation by carrying
out a measurement.
