DANGER : ELECTRICAL HAZARD!!

To avoid serious injury, please follow the procedure below.

- Switch off external AC circuit breaker or switch to disconnect the electrical grid from

the inverter chassis.

- Switch off both DC switches to cease inverter operation.
- Use H4 wrench tool to disconnect each string from the chassis mounted H4

terminals.

Remove array DC from chassis requires opening string level H4 connectors in order

to break string continuity at the inverter H4 connectors are not intended for use as a

load break switch, therefore:

Ensure inverter DC switches are open and there is no DC current flow.

■

RS-485 Communication module

1. Disconnect all communications wiring from the module terminals.

2. Remove wiring from communications board assembly.

5.5 De-Commissioning

When necessary to remove the inverter from active operation for maintenance
or replacement, follow the instructions below.
