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.
1. If the unit is not equipped with an optional factory
installed nonfused disconnect switch or circuit
breaker, a field supplied disconnect switch must be
installed at or near the unit in accordance with the
National Electrical Code (NEC latest edition).
2. Location of the applicable electrical service
entrance is illustrated in the
section. 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
circuit breaker (UCB), or the electric heat terminal
block. Refer to the customer connection diagram
that shipped with the unit for specific termination
points.
3. Provide proper grounding for the unit in accordance
with local and national codes.
Optional TBUE Wiring (Through the Base
Electrical Option)
1. Location of the applicable electrical service is
illustrated in the following illustration. 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 (UDC) or circuit breaker
(UCB).
2. Provide proper grounding for the unit in accordance
with local and national codes.
