Mouting Procedure

Use the following procedure to mount an RS-422/485 Communications Unit
SI-485/J7 (3G3JV-PSI485J) to a J7AZ Inverter.

Turn OFF the Inverter’s power supply. Mounting the RS-422/485
Communications Unit without turning OFF the Inverter’s power supply may
result in electric shock or damage to equipment.

Loosen the Inverter’s front cover mounting screws and remove the front
cover as shown on the left below.

Remove the optional cover as shown on the right below.
