Grounding Connections
General Information
The connection of the equipment grounding conductors of the devices and
their connection to the equipment grounding system are indispensable for the
electrical safety of the drive system.
Dangerous contact voltage at device housing!
Lethal electric shock!
WARNING
The devices of the Rexroth IndraDrive product range are devices with in‐
creased leakage current (greater than AC 3.5 mA or DC 10 mA). Therefore,
always install a stationary connection of the equipment grounding conductor.
