Wiring schematic for 4 lead motors, single phase
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.
208/230 Volt Three Phase Fans
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
For 460 volt operation, Orange (W2), Red (U2) and
Grey (V2) wires must be spliced together.
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.
