To use a communication option, the enclosed earthing (grounding) cable needs to be installed. Install the cable according to the
following procedure:
Insert spacers into the mounting holes that will not be tightened with the option mounting screws.
Fit the connector of the communication option to the guide of the connector of the inverter, and insert the option as far as it

Remove the mounting screw (lower) of the Ethernet board earth plate. Fit the one terminal of the earthing (grounding) cable
on the Ethernet board earth plate and fix it securely to the inverter with the mounting screw (tightening torque 0.33 Nm to
0.40 Nm).
Fix the left part of the communication option securely with the option mounting screw, and place another terminal of the
earthing (grounding) cable on the right part of the option and fix the cable terminal and the option with the option mounting
screw (tightening torque 0.33 Nm to 0.40 Nm).
