screws where shown
to hold side in rotated
position. Pilot holes are
provided.
b. Rotate opposite side up on weatherhood and

Installation of Electrical Wiring
IMPORTANT
Before connecting power to the unit, read and
understand the following instructions and the wiring
diagrams. Complete wiring diagrams are attached to
the inside of the control center door(s).
All wiring should be done in accordance with the
latest edition of the National Electrical Code ANSI/
NFPA 70 and any local codes that may apply. In
Canada, wiring should be done in accordance with
the Canadian Electrical Code.
The equipment must be properly grounded. Any
wiring running through the unit in the airstream must
be protected by metal conduit, metal clad cable or
raceways.
CAUTION
If any of the original wire must be replaced, the
replacement wire must have a temperature rating of
at least 105°C, except for energy cut-off or sensor
lead wire which must be rated to 150°C.
Any wiring deviations may result in personal injury or
property damage. Manufacturer is not responsible
for any damage to or failure of the unit caused by
incorrect final wiring.
DANGER
High voltage electrical input is needed for this
equipment. This work should be performed by a
qualified electrician.
1. Determine the Size of the Main Power Lines: The
unit nameplate states the unit’s voltage and total
MCA. The main power lines to the unit should be
sized accordingly. The nameplate is located on the
outside of the unit on the control panel side.
2. Provide the Opening(s) for the Electrical
Connections: Electrical openings vary by unit size
and arrangement and are field-supplied.
3. Connect the Main Power: Connect the main power
lines to the disconnect switch and main grounding
lug(s). Torque field connections to 20 in.-lbs. See the
control center layouts in the Reference section for
