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
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 cor-
respond to schematics above, wire according to the code on the band.
