5. COMMISSIONING

WARNING:

CONNECT AU-1P20002G TO THE ELECTRICAL UTILITY GRID ONLY AFTER RECEIVING

PRIOR APPROVAL FROM THE UTILITY COMPANY.

WARNING:

BE AWARE THAT ONLY QUALIFIED PERSONNEL CAN CONNECT

ELECTRICAL UTILITY GRID.

WARNING:

ENSURE THAT ALL AC AND DC WIRING IS CORRECT. ENSURE THAT NONE OF THE AC AND

DC WIRES IS PINCHED OR DAMAGED. ENSURE THAT ALL JUNCTION BOXES ARE PROPERLY CLOSED.

Following these steps to commission the AU-1P20002G PV system:

1. Turn on the AC disconnects or circuit breakers on each AU-1P20002G AC branch

circuit.

2. Turn on the main utility-grid AC circuit breaker. Your system will start producing

power after a few minutes wait time.

3. The AU-1P20002G will start to send performance data over the power lines using

power line communication (PLC) to the AUG-256. The time required for each

AU-1P20002G in the system to communicate to the AUG-256 will vary with the

number of AU-1P20002G in the system.

6. OPERATING INSTRUCTIONS

The AU-1P20002G is powered on when sufficient DC voltage from the module is

applied. The status LED will start flashing after sufficient DC power is applied as an

indication that the AU-1P20002G is live.

Status: standby

The LED light is on by 2 second, and off by 2 seconds

Red: in error.

Orange: no error, but not communicating to AUG-256

Green: no error, and communicating to AUG-256

Status: producing power

The LED light is on by 1 second, and off by 1 second.

Orange: not communicating to AUG-256

Green: communicating to AUG-256

AU-1P20002G

TO THE

Status: grounding fault

The LED light is in solid red color.

In case of fault, AUM inverter has multiple protective functions and stops output

power. The fault message may be sent to a connected AUG-256 gateway through

power line communication. For AUM-WiFi, the same alert is sent through WiFi

internet connection, and can be monitored through AustaViewer (please refer to

the tech note "Configuring AUM WiFi"). The alert message is a 16-bit code

7. TROUBLESHOOTING AND MAINTENANCE

WARNING:

DO NOT ATTEMPT TO REPAIR THE AUM-2000; IT CONTAINS NO

USER-SERVICEABLE PARTS. IF TROUBLESHOOTING METHODS FAIL, PLEASE RETURN THE

AUM-2000 TO YOUR DISTRIBUTOR FOR MAINTENANCE.

WARNING:

NEVER DISCONNECT THE DC WIRE CONNECTORS UNDER LOAD. ENSURE THAT

NO CURRENT IS FLOWING IN THE DC WIRES PRIOR TO DISCONNECTING. AN OPAQUE

COVERING MAY BE USED TO COVER THE MODULE PRIOR TO DISCONNECTING

WARNING:

AUM-2000 IS POWERED BY DC POWER FROM PV MODULES. MAKE SURE YOU

DISCONNECT THE DC CONNECTIONS AND RECONNECT DC POWER TO WATCH FOR THE TWO

SECONDS LED ON AND TWO SECONDS LED OFF AFTER DC IS APPLIED.
