Wiring
Energy Wheel Motor
A separate power source for the energy wheel motor is required.
The energy wheel section is provided with fuses, a disconnect
switch, and a starter located in the exhaust fan starter cabinet. The
power connection for the energy wheel motor is made to a terminal
block at this point. Follow all national and local electrical codes for
running power to the terminal block. Refer to Table 6 for the energy
wheel voltage and amperage requirements. Refer to the factory
sales order to determine the energy wheel size. Voltage and
amperage specifications can also be found on the energy wheel
motor nameplate located inside the energy wheel section.

CAUTION
Do not install a variable frequency drive (VFD) to control the
energy wheel speed. This may result in failure of the energy
wheel motor.
Optional Air Bypass Damper Actuators: If actuators are factory-
provided, no field wiring is required.
Field-Provided Damper Actuators: If bypass damper actuators are
field-provided, it will be necessary to remove two or three
segments from the energy wheel to gain access to the damper. See
the "Routine Maintenance" section on page 16 for the segment
removal procedure.
