Bryant 569J 08G Series Installation, Start-Up And Service Instructions Manual page 11

Field Power Supply —
If equipped with optional Powered Convenience Outlet:
The power source leads to the convenience outlet's
transformer primary are not factory connected. Installer
must connect these leads according to required operation
of the convenience outlet. If an always-energized
convenience outlet operation is desired, connect the
source leads to the line side of the unit-mounted
disconnect. (Check with local codes to ensure this method
is acceptable in your area.) If a de-energize via unit
disconnect switch operation of the convenience outlet is
desired, connect the source leads to the load side of the
unit disconnect. On a unit without a unit-mounted
disconnect, connect the source leads to compressor
contactor C and indoor fan contactor IFC pressure lugs
with unit field power leads..
Refer to Fig. 13 for power transformer connections and the
discussion on connecting the convenience outlet on page 12.
Field power wires are connected to the unit at line-side
pressure lugs on compressor contactor C and TB1 (see
wiring diagram label for
arrangement) or at factory-installed option non-fused
disconnect switch. Max wire size is #4 AWG (copper only).
NOTE: TEST LEADS - Unit may be equipped with short
leads (pigtails) on the field line connection points on
contactor C or optional disconnect switch. These leads are
for factory run-test purposes only; remove and discard
before connecting field power wires to unit connection
points. Make field power connections directly to line
connection pressure lugs only.
