Connecting a protective earth to Argon drive is the most crucial single connection to be made:

  • Earthing through the J4 PE terminal (always required)
  • Earthing the heat sink (always required)
  • Earthing the device case (always required)


Earthing through the J4 PE terminal

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

Earthing the heatsink

Earthing points of the heatsink
Proper earthing wire installation with toothed locking washers ensure an electrical contact through surface coatings.
Attaching protective earth wire to the heatsink and case is mandatory in addition to the PE connection in J4 terminal.

Parts needed:

  • 1pcs wire ring terminal with 4-5.5 mm hole with at least 20 Ampere capable earthing conductor
  • 2pcs M4 serrated/toothed lock washers
  • 1pcs M4 screw, 6-8 mm thread length

Verifying connection

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.
