Most factory-supplied electrical components are pre-
wired. To determine what electrical accessories require
additional field wiring, refer to the unit-specific wiring
diagram located on the inside of the unit control center
access door. The low voltage control circuit is 24 VAC
and control wiring should not exceed 0.75 ohms.
Control wires should not be run inside the same conduit
as that carrying the supply power. Make sure that field-
supplied conduit does not interfere with access panel
operation.
If wire resistance exceeds 0.75 ohms, an industrial-style
plug-in relay should be added to the unit control center
and wired in lieu of the remote switch (typically between
terminal blocks R and G on the terminal strip (refer to
Typical Control Center Components). The relay must be
rated for at least 5 amps and have a 24 VAC coil. Failure
to comply with these guidelines may cause motor
starters to “chatter” or not pull in which can cause
contactor failures and/or motor failures.
Note: Standard factory-installed electric post-heaters
have their own disconnect separate from the
unit disconnect. Thus, each electric post-heater
requires its own separate power connection.
