High Voltage Field Wiring
NOTE: All field wire to be rated 75°C minimum.
Maximum field wire size is 2/0 AWG.
1. Check to make certain the proper size fuses are installed
per the fuse table (located on the wiring diagram) and
Tables 2 (page 3), 3 (page 3), and 4 (page 4) for the par-
ticular SPEK being used.
2. Remove the required electrical knockout from the unit
conduit panel and route the field wires through the unit
heater section (not the Control Box section).
3. Connect the power supply to the terminal block or fuse
block (depending on SPEK kit being used) on the SPEK.
See appropriate wiring diagram for hookup connections.
Connect the power supply ground wire to the ground
lug on the single power entry kit. The BAYSPEK060E
and 061E wire terminals connect to the installed heater
terminal block on the Heater Control box base to power
the unit.
4. Close the Heater/SPEK control box cover.
5. Reinstall the Control/Heat access panel.
6. Apply power to unit.
Low Voltage Wiring (24 Volts)
All low voltage connections have been made to the heater
via polarized plugs. The low voltage controls are connected
to the room thermostat from the air conditioner or heat
pump low voltage leads. See the field wiring diagram with
the unit.
Install Single Power Entry Kit
1. Remove the Control/Heat access panel.
2. Open the louvered Heater Control box door and mount
the SPEK inside of the Heater Control box. Secure the
SPEK with the screws provided in the kit. See pages

3. Insert the included grommet in the hole in the Heater
Control box base that leads to the unit Control/Heater
compartment. The unit power wires provided with the
SPEK will pass through this grommet and be routed
up to the unit contactor.
4. Make all electrical connections to the unit and heater
in accordance with the appropriate wiring diagram in
this instruction and included with the specific SPEK.
5. Place the included SPEK wiring diagram on the inner
surface of the Control/Heater access panel next to the
unit wiring diagram and extra heater wiring diagram.

the single power entry kit must be attached to the air con-
ditioning unit or heat pump unit as illustrated below.
The smaller label
MUST be placed over the unit rating
nameplate to cover the unit only MIN CKT AMPS and

The “single power entry installed” nameplate
MUST be
