Connecting a protective earth to Argon drive is the most crucial single connection to be made. Argon has two earthing methods:

  • Connect protective earth to J4 PE terminal (always required)
  • Connect earthing wire directly to the metal case (highly recommended and may be required by regulations in some countries)


Earthing the J4 PE terminal

This is a mandatory connection. Follow the Argon wiring instructions.

Earthing the case

Earthing points of the case
Proper earthing wire installation with toothed locking washers ensure an electrical contact through surface coatings.
Attaching protective earth wire to the case can provide much lower impedance PE connection compared to the J4 terminal making it highly recommended addition to grounding. Using both methods also provides redundancy in the case of one method fails.

After wiring, verify electrical connection by using a resistance meter between the case PE wire and J4 PE terminal while J4 PE wire is not connected.
