Wiring/Disconnect Box
The wiring/disconnect box is standard for all North American models of the
inverter. The wiring/disconnect box provides a location for making AC, DC and
ground connections. It also contains the DC/AC (PV array/utility) disconnect
switch. When used with the inverter, the DC/AC disconnect switch is 600V AC
and DC rated and is identified on the outside by an illustration showing the open
and closed switch positions. The switch is lockable, and meets NEC Section 690
requirements as a means of disconnect.
WARNING: Shock hazard
The 600 volt DC/AC disconnect in the wiring/disconnect box meets NEC Article 690. It is
a non-serviceable component and shall remain in place. Separating the inverter and
wiring/disconnect box, or removing the wiring/disconnect box cover can expose
energized conductors. PV input circuits in the wiring box ahead of the switch remain
energized even when the switch is in the “off” position—hazardous voltage will still be
present on the DC input (PV) terminals under the clear plastic insulation barrier inside the
wiring/disconnect box.
