Installation Procedure
1. Turn the inverter ON/OFF/P switch to OFF. Wait 5 minutes for the capacitors to discharge.
2. Turn the Safety Switch (if applicable) to OFF.
3. Disconnect the AC to the inverter by turning OFF the circuit breakers on the distribution panel.
4. Open the inverter cover screws and remove the cover.
5. Perform one of the following actions:
For a new RS485 connection installation, disconnect the 6-pin connector from the surge protection board, and connect
the two sets of RS485 wires to the G, A, and B terminals, as shown in the figure below.

If RS485 connection is already installed in the inverter, disconnect the 6-pin connector from the inverter’s communication
board (leaving the RS485 wires intact).

6. Screw the standoff spacer into its socket as shown in the below figure. Place the surge protection device over the spacer so
that the screw opening is aligned with the spacer, and insert the screw into the spacer via the indicated screw opening in the
device. Do not tighten the screw at this point.

8. Tighten the screw securing the surge protection device (torque 1.1 N*m/ 0.8 lb*ft), as shown in Figure 4.
9. Connect the 6-pin connector to the surge protection device.
10. Close the inverter cover.
11. Turn ON the AC to the inverter.
12. Turn the Safety Switch (if applicable) to ON.
13. Turn the inverter ON/OFF/P switch to ON.
