Note:
1. Conductors – UL listed 600V, 105° C copper stranded.
Size conductors per NEC at 125% of motor full load amps
(#14 AWG. Min.). Size conduit per NEC for size & number of
conductors.
2. If motor is provided with thermal overloads, overloads may be
omitted in the magnetic starter.
3. All material & components must be UL or ETL listed or recognized.
4. To verify correct fan rotation, momentarily energize motor. If rotation
is incorrect, (for 3 phase), reverse any two incoming line conductors,
(for 1 phase), interchange conductors 5&8. See wiring diagram on
motor.
