a customer--option. If local codes permit, the transformer
primary leads can be connected at the line--side terminals on
the unit--mounted non--fused disconnect; this will provide
service power to the unit when the unit disconnect switch is
open. Other connection methods will result in the
convenience outlet circuit being de--energized when the unit
disconnect switch is open. See Fig. 36. On a unit without a
unit--mounted disconnect, connect the source leads to the
main terminal block (TB1).

Fuse on power type: The factory fuse is a Bussman
“Fusetron” T--15, non--renewable screw--in (Edison base)
type plug fuse.
If the convenience outlet transformer is connected to the line
side of a field disconnect, the conduit provided with the unit
must be used to protect the wire as they are routed from the
transformer to the field disconnect. The end of the conduit
with the straight connector attaches to the field disconnect.
The other end does not need to connect to 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.

Fig. 37 -- Convenience Outlet Utilization Notice
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.
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal
injury or death.
Using unit--mounted convenience outlets: Units with
unit--mounted 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.

WARNING
Installing Weatherproof Cover:
A weatherproof
while-in-use cover for the factory-installed convenience
outlets is now required by UL standards. This cover
cannot be factory-mounted due its depth; it must be
installed at unit installation. For shipment, the
convenience outlet is covered with a blank cover plate.
The weatherproof cover kit is shipped in the unit’s control
box. The kit includes the hinged cover, a backing plate
and gasket.

-in (13 mm) under screw heads are
exposed. Press the gasket over the screw heads. Slip the
backing plate over the screw heads at the keyhole slots
and align with the gasket; tighten the two screws until
snug (do not over-tighten).
Mount the weatherproof cover to the backing plate as
shown in Fig. 38. Remove two slot fillers in the bottom of
the cover to permit service tool cords to exit the cover.
Check for full closing and latching.
