De-Energize/Isolation Procedure
The following procedure should be followed to de-energize the Inverter for
maintenance.
To isolate the Inverter:
1. Turn the main
ON/OFF switch (S3) to the OFF position.
2. Open the utility connection circuit breaker.
3. Open the AC Disconnect.
4. Open the DC Disconnect Switch.
5. Install lockout devices on the utility connection circuit breaker, AC and
DC disconnect switch.
Interconnection Standards Compliance
The Ethernet Communications Kit complies with IEEE C37.90.1
requirements.
The Inverter complies with FCC Part 15 Class A requirements.
The Inverter is designed to meet NEC Article 690 and UL1741-2005 Static
Inverters And Charge Controllers For Use In Photovoltaic Power Systems,
which includes testing for IEEE 1547.1-2005, IEEE 929-2000 and IEEE
519-2000.
Intended Use
The Ethernet Communications Kit may only be used in GT Series Three
Phase Grid Tie Inverters. It is not suitable for any other application areas.
WARNING
The terminals of the DC input may be energized if the PV arrays are energized. In
addition, allow five minutes for all capacitors within the main Enclosure to
discharge after disconnecting the Inverter from AC and DC sources.
