Standard Wiring
The electrical service must be protected from over
current and short circuit conditions in accordance with
NEC requirements.
Protection devices must be sized according to the
electrical data on the nameplate.
• If the unit is not equipped with an optional factory
installed nonfused disconnect switch, a field
supplied disconnect switch must be installed at or
near the unit in accordance with the National
Electrical Code (NEC latest edition).
• Location of the applicable electrical service
entrance is illustrated in “Dimensional Data,” p. 9.
Complete the unit’s power wiring connections onto
either; the main terminal block HTB1 inside the unit
control panel, the factory mounted nonfused
disconnect switch (UCD), or the electric heat
terminal block. Refer to the customer connection
diagram that shipped with the unit for specific
termination points.
• Provide proper grounding for the unit in accordance
with local and national codes.
Optional TBUE Wiring (Through the Base
Electrical Option)
• Location of the applicable electrical service is
illustrated below. Refer to the customer connection
diagram that is shipped with the unit for specific
termination points. The termination points,
depending on the customer option selected, would
be a factory mounted nonfused disconnect switch
(see Figure 14, p. 22 ), the electric heat terminal
block (if equipped) or the main terminal block.
• Provide proper grounding for the unit in accordance
with local and national codes.

The 24-volt control power transformers are to be used
only with the accessories called out in this manual.
Transformers rated greater than 50 Vac are equipped
with internal circuit breakers. If a circuit breaker trips,
turn “Off” all power to the unit before attempting to
reset it.
The transformer is located in the control panel. The
circuit breaker is located on the left side of the
transformer and can be reset by pressing in on the
black reset button.
Controls using 24 Vac
Before installing any connecting wiring, refer to
“Dimensional Data,” p. 9 for the electrical access
locations provided on the unit and Table 2, p. 19 for AC
conductor sizing guidelines.
