Connecting the DC Wiring
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).
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
