2.3 Electrical Connection
Do not proceed with the electrical connection of the StarInverter until it has been properly
mounted.
WARNING: Electrical connections must be done in accordance with local
electrical codes and the National Electrical Code (NEC), ANSI/NFPA 70. Use 10
AWG, minimum 90° (194°F), copper wire for all PVP1800 and PVP2800
connections. Voltage drop as well as other considerations may dictate that
larger wire sizes be used.
WARNING: Make sure the main 120/208/240 volt breaker in the main
utility breaker box is switched OFF before wiring the StarInverter. This breaker
should be switched ON only after all wiring has been completed as set forth in
this manual.
WARNING: Follow the order listed below in wiring the StarInverter. Failure
to do so may result in hazardous voltages or disconnection of contacts.
Terminal connections for the StarInverter are located inside the inverter on the circuit
board at the bottom of the box. Solid wires up to 8 AWG (6mm²) and flexible wires up to
10 AWG (4mm²) are accepted by the AC terminals. Wires up to 6 AWG are accepted by
the DC terminals.
CAUTION: The input and output circuits are isolated from the enclosure.
System grounding, when required by Sections 690-41, 690-42, and 690-43 of
the National Electric Code (NEC), ANSI/NFPA 70-1999, is the responsibility of
the installer.
