Field Control Wiring — The 580J unit requires an external tem-
perature control device. This device can be a thermostat emulation
device provided as part of a third-party Building Management
System.
Thermostat — Install a Bryant-approved accessory 2-stage ther-
mostat according to installation instructions included with the ac-
cessory. Locate the thermostat accessory on a solid wall in the
conditioned space to sense average temperature in accordance
with the thermostat installation instructions.
If the thermostat contains a logic circuit requiring 24-v power,
use a thermostat cable or equivalent single leads of different colors
with minimum of seven leads. If the thermostat does not require a
24-v source (no “C” connection required), use a thermostat cable
or equivalent with minimum of six leads. Check the thermostat in-
stallation instructions for additional features which might require
additional conductors in the cable.
For wire runs up to 50 ft. (15 m), use no. 18 AWG (American
Wire Gage) insulated wire [35°C (95°F) minimum]. For 50 to
75 ft. (15 to 23 m), use no. 16 AWG insulated wire [35°C (95°F)
minimum]. For over 75 ft. (23 m), use no. 14 AWG insulated wire
[35°C (95°F) minimum]. All wire sizes larger than no. 18 AWG
cannot be directly connected to the thermostat and will require a
junction box and splice at the thermostat.

Unit Without Thru-Base Connection Kit — Pass the thermo-
stat control wires through the hole provided in the corner post;
then feed the wires through the raceway built into the corner
post to the control box. Pull the wires over to the terminal strip
on the upper-left corner of the Controls Connection Board. See
Fig. 54.
NOTE: If thru-the-bottom connections accessory is used, refer
to the accessory installation instructions for information on
routing power and control wiring.

FACTORY-OPTION THRU-BASE CONNECTIONS
(ELECTRICAL CONNECTIONS) (SIZE 16) —
This
service connection kit consists of a 1 /
2
in. electrical bulkhead con-
nector and a 1 1 /
2
in. electrical bulkhead connector, connected to
an “L” bracket covering the embossed (raised) section of the unit
basepan in the condenser section. See Fig. 55. The 1 /
2
in. bulkhead
connector enables the low-voltage control wires to pass through
the basepan. The 1 1 /
2
in. electrical bulkhead connector allows the
high-voltage power wires to pass through the basepan.

(Size 16)
1. Remove the “L” bracket assembly from the unit.
2. Remove connector plate assembly from the “L” bracket and
discard the “L” bracket, but retain the washer head screws
and the gasket (located between the “L” bracket and the con-
nector plate assembly).
NOTE: Take care not to damage the gasket, as it is reused in the
following step.
3. Place the gasket over the embossed area in the basepan,
aligning the holes in the gasket to the holes in the basepan.
See Fig. 56.
4. Install the connector plate assembly to the basepan using 8 of
the washer head screws.
NOTE: If electrical connections are not going to occur at this
time, tape or otherwise cover the fittings so that moisture does not
get into the building or conduit in the interim.
