INSTALLATION

2.3 Communication cable

When making a cable for the Modbus Plus protocol, make sure that each

end of the cable is terminated with the A5MBKT185 terminator connectors.

For nodes between the termination points, use the in-line connectors

(A5MBKT085). The cable should be a Modbus Plus standard cable

(490NAA271xxF).

Connect a wire from the ground terminal on the FR-A5NM to the

inverter Chassis to ensure proper grounding of the option board.
