2.3 Electrical Connection
Do not proceed with the electrical connection of the SunPower Inverter 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 the SPR-5200, SPR-4600 connections. Voltage drop as well as other
considerations may dictate that larger wire sizes be used.
WARNING: Make sure the main 240-volt breaker in the main utility breaker box is
switched OFF before wiring the SunPower Inverter. 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 SunPower Inverter.
Failure to do so may result in hazardous voltages or disconnection of contacts.
IMPORTANT: Only raintight or wet location conduit hubs that comply with the
requirements in the Standard for Fittings for Conduit and Outlet Boxes, UL 514B, are
to be used.
Terminal connections for the SunPower Inverter 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.
