Wiring the Inverter

Connecting the DC Wiring

WARNING: Shock hazard

Whenever a PV array is exposed to sunlight, a shock hazard exists at the output wires or exposed terminals. Ensure that the AC/DC Disconnect Switch is set to OFF before commencing any wiring. See Figure 3-3.

WARNING: Shock hazard

The 600 volt AC/DC disconnect in the wiring box meets NEC Article 690. It is a non-serviceable component and shall remain in place. Removal can expose energized conductors.

Figure 3-3AC/DC Disconnect Switch Positions

The following procedure is illustrated in Figure 3-4. If there will be more than one PV string, label the positive and negative wire pairs appropriately (for example: PV 1, PV 2).
