Chapter 2
Installing the Option Board
Power down the inverter and wait at least five minutes before moving to the next step. Open and remove the
lower terminal cover. Confirm that the red CHARGE LED is extinguished and that the DC bus is fully
discharged before proceeding further, otherwise there is the danger of electric shock. Then remove keypad from
the inverter. You can now remove the upper front cover to expose the two option ports inside.
Figure 2-3 below shows how to install the option board to option port 1 or 2 of the inverter. There are four holes
on the corners of the option board. Align the board with the port connector in the proper orientation (to the left,
when facing the inverter as show). Then align the top two holes with the two screw holes, and the bottom two
holes with the two guide posts. Insert the board fully into the connector. Secure the board with the two M3
screws supplied.
