On/Off Switch
The PV225S incorporates a maintained position ON/OFF Switch (S3) located on
the front door of the main enclosure. Under normal conditions, the O
N/OFF switch
is in the
ON position. Turning the switch to the OFF position will initiate an
immediate controlled shutdown of the PV225S and open both the main AC and
DC contactors within the unit. The main AC and DC contactors cannot be closed
unless the switch is in the O
N position. The PV225S is prevented from being
restarted until the O
N/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 page 5–3.
