WARNING: Shock hazard
Whenever a PV array is exposed to sunlight, a shock hazard exists at the output wires or
exposed terminals. To reduce the risk of shock during installation, cover the array with an
opaque (dark) material and ensure that the DC/AC Disconnect Switch is set to OFF before
commencing any wiring. See Figure 3-3.
WARNING: Shock hazard
The 600 volt DC/AC 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.
WARNING: Shock hazard
Use caution when working around sources of DC power. Although the DC/AC disconnect
switch disconnects the inverter from DC power, hazardous voltages from paralleled PV
strings may still be present upstream of the switch. Before servicing a PV string, isolate
each string by completely removing PV wiring from the inverter terminal block.
