the transformer; however, the conduit must be routed so
that all wiring is either in the conduit or behind the access
panel.
If the convenience outlet transformer is connected to the
line side of the factory disconnect option, route the wires
through the web bushing located on the bottom of the
disconnect box. For the load side wiring to the factory
option disconnect, route the wires through the hole on the
right side of the disconnect. Be sure to create a drip loop
at least 6" long.
Duty Cycle: the unit- - powered convenience outlet has a
duty cycle limitation. The transformer is intended to
provide power on an intermittent basis for service tools,
lamps, etc; it is not intended to provide 15- - amps loading
for continuous duty loads (such as electric heaters for
overnight use). Observe a 50% limit on circuit loading
above 8- - amps (i.e., limit loads exceeding 8- - amps to 30
minutes of operation every hour).
Test the GFCI receptacle by pressing the TEST button on
the face of the receptacle to trip and open the receptacle.
Check for proper grounding wires and power line phasing
if the GFCI receptacle does not trip as required. Press the
RESET button to clear the tripped condition.

WARNING
!
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal
injury or death.
Using unit- - mounted convenience outlets: Units with
unit- - mounded convenience outlet circuits will often
require that two disconnects be opened to de- - energize
all power to the unit. Treat all units as electrically
energized until the convenience outlet power is also
checked and de- - energization is confirmed. Observe
National Electrical Code Article 210, Branch Circuits,
for use of convenience outlets.
