On/Off Switch
The PV225S incorporates a maintained position ON/OFF Switch (S3) located on
the front door of the main enclosure. Under normal conditio ns, the ON/OFF switch
is in the ON position. Turning the switch to the OFF position will init iate an
immediate controlled shutdown of the PV225S and open both the m ain AC and
DC contactors within the unit. The main AC and DC contactors ca nnot be closed
unless the switch is in the ON position. The PV225S is prevented from being
restarted until the ON/OFF switch is turned back to the ON position.
WARNING: Shock Hazard
Disengaging the main enclosure door interlock switch does NOT remove all hazardous
voltages from inside the inverter. Before attempting to service the PV225S, follow the
de-energize Lockout and Tag procedure on page5–3.
