115/230 Volt Single Phase Fans
Wiring schematic for 4 lead motors, single phase
Notes:
1. All leads are color coded
as well as identified with an
Alpha/Alpha or Alpha/
Numeric code (i.e. TK or
Z2). This code may be
shown as a band on the
wire or on a schematic on
the motor hub. Colors
should be verified against
code band. If code band and color do not correspond to schematics above,
wire according to the code on the band.
2. Color of capacitor leads may be reversed. Fan operation will not be
affected.
230 Volt Three Phase Fan
Notes:
1. Contactor should be used.
Control coil should be
wired in series with motor
thermal contacts (TK
leads) as shown in diagram
to provide thermal motor
protection.
2. All leads are color coded as well as identified with a band containing an
Alpha/Alpha or Alpha/Numeric code (i.e. TK or Z2). Colors should be verified
against code band. If code band and color do not correspond to schematics
above, wire according to the code on the band.

460 Volt Three Phase Fan
Important note: For 460 volt operation, Orange (W2), Red (U2) and
Grey (V2) wires must be spliced together.
Notes:
1. Contactor should be used.
Control coil should be wired
in series with motor thermal
contacts (TK leads) as shown
in diagram to provide thermal
motor protection.
2. All leads are color coded as
well as identified with a band containing an Alpha/Alpha or Alpha/Numeric
code (i.e. TK or Z2). Colors should be verified against code band. If code
band and color do not correspond to schematics above, wire according to
the code on the band.
