Connecting additional protective grounding

If additional protective grounding or equipotential bonding is required locally, you can connect additional protective grounding to the product. This prevents touch current if the grounding conductor at the terminal for the AC cable fails.

Additionally required material (not included in the scope of delivery):

  • 1 grounding cable

  • 1 ring terminal lug M5

Cable requirements:

  • The cable cross-section must correspond at least to the cross-section of the grounding conductor connected to the terminal block for the AC connection.

Procedure:

  1. Dismantle the grounding cable.

  3. Clean the contact surfaces of the terminal lug using a clean cloth and ethanol cleaning agent and do not touch the contact surfaces after cleaning.
