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 re-
ceptacle does not trip as required. Press the RESET button to
clear the tripped condition.
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. Ob-
serve National Electrical Code Article 210, Branch Circuits, for
use of convenience outlets.
FACTORY-OPTION THRU-BASE CONNECTIONS
(ELECTRICAL CONNECTIONS) —
All units are
equipped with the ability to bring utilities through the base.
Gas is brought up through an embossed area located in the
gas section behind the gas entrance post. Access is gained
through the gas access panel. A knock out must be removed to
accomplish this.
The electrical entrance is located in the control box area and
can be accessed through the control box access panel. An em-
bossed area is provided with three knock outs. High voltage is
brought through the multi knock out by removing the appropri-
ate size for the size of the fitting required. A
7
/
8
-in. knock out is
provided for low voltage. An additional
7
/
8
-in. knock out is pro-
vided for a 115 volt line which is used when the unit is equipped
with the non-unit powered convenience outlet option.
All required fittings are field supplied. Install fittings when
access to both top and bottom of the base pan is available. See
electrical and gas connections for routing and connection infor-
mation.
Units Without Thru-Base Connections
1. Install liquid tight conduit between disconnect and con-
trol box.
2. Pull correctly rated high voltage wires through the conduit.
3. Install power lines to terminal connections as shown in
Fig. 26.
Field Control Wiring — The 580J unit requires an external
temperature control device. This device can be a thermostat
(field-supplied) or the RTU Open for Building Management
Systems using non-CCN protocols (RTU Open is available as a
factory-installed option only).
Thermostat — Install a Bryant-approved accessory 2-stage ther-
mostat according to installation instructions included with the
accessory. 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 pow-
er, 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 ther-
mostat cable or equivalent with minimum of six leads. Check the
thermostat installation 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 minimum). For 50 to 75 ft
(15 to 23 m), use no. 16 AWG insulated wire (35°C minimum).
For over 75 ft (23 m), use no. 14 AWG insulated wire (35°C
minimum). All wire sizes larger than no. 18 AWG cannot be di-
rectly connected to the thermostat and will require a junction
box and splice at the thermostat.
Unit Without Thru-Base Connection Kit — Correctly rated
low voltage wire can be routed through the rubber grommet
located on the corner post adjacent to the control box access
panel. Route wire through the grommet and then route the
wire behind the corner post utilizing the factory provided
wire ties secured to the control box. This will ensure separa-
tion of the field low voltage wire and the high voltage circuit.
Route the low voltage wire to the central terminal board. See
Fig. 31.
NOTE: If utilizing the through the base connections, route the
low voltage wire through the wire ties to the central terminal
board.
