Installing a communication option (FR-A800-E)

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 goes. (Insert it to the inverter option connector 1.)
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).
If the screws are not tightened properly, the connector may not be inserted deep enough. Check
