Motor Nameplate Data
The 39 Series air-handling unit nameplates do not contain fan mo
-
tor electrical data. The units as manufactured, are certified to meet
all requirements, including unit markings, of UL1995 “Standard
For Safety-Heating and Cooling Equipment.”
The motor nameplate should be relied on to carry the motor elec
-
trical data. Here are several reasons the motor data is not on an ex
-
ternal nameplate, separate from the motor:
1. Many units are shipped without motors, and the installing
contractor provides field-supplied motors.
2. Typically, the motors provided are triple voltage motors and
may be wired at the job site for 208, 230, or 460-volt power,
as necessary.
3. The motor nameplate, which contains all necessary electrical
information, is easily accessible inside the fan section.
4. Motor changes are quite often required during testing and bal
-
ancing to meet actual job conditions. External nameplates
could easily be left unchanged by the installing contractor.
NOTE: Where field wiring of motor is required, wire per instruc
-
tions located in motor terminal box or on motor nameplate. See
Fig. 117.

MOTOR WIRING INSTRUCTIONS
INSIDE JUNCTION BOX
NOTES:
1. If the motor has 12 leads and wiring diagrams for both Wye and
Delta OR Start and Run connections, ALWAYS wire to the RUN
or DELTA connections with an across-the-line motor starter or
VFD. Failure to do so will result in motor and/or starter/VFD
damage.
2. Low-voltage motors include 190, 200, 208, and 230-v.
3. High-voltage motors include 380, 400, 460, and 480-v.
