INSTALLATION INSTRUCTIONS (CONTINUED)
Grounding
This product must be grounded. Grounding reduces the risk of electrical shock by providing an escape wire for
the electric current if short circuit occurs. This product must be installed and operated with a power cord or cable
that has a grounding wire.
Breakers and Fuses
The entire electrical system should be checked by a certified electrician. Time delay breakers and fuses are
required for this compressor. A tripped breaker or blown fuses may indicate a direct short to ground, high current
draw, improper wiring, incorrect fuse or breaker size and/or type. This needs to be evaluated by a certified
electrician.
Motor Hookup and Starter Installation
Branch circuit protection must be provided as specified
in the United States National Electrical Code, Chapter
2, "Wiring Design and Protection." Article 210, using the
applicable article "For Motors and Motor Controllers,"
(Article 430, Table 430-1 52).
IMPORTANT: Overload protection is required for all
motors.
Motors used on the Shop Air Series do not have built-in
overload protection. A magnetic starter is required. Refer
to the following wiring diagrams for electrical installation
(Figures 8 & 9):
Three phase motors are tri-voltage rated: 208-230/460.
They are shipped from the factory pre-wired for 208-230
volt operation. If 460 volt operation is desired, some
rewiring is required.
1. Rewire the motor leads for 460 volt per motor data
plate.
2. Install the 460 volt conversion kit, part numbers are
listed below. Both the coil and the thermal overload elements in the magnetic starter must be changed (see
Figure 6).

Direction of Rotation

NOTE: Improper rotation will result in reduced
compressor life.
The direction of rotation must be counterclockwise
(as shown by the arrow on the flywheel in Figure
7) while facing the flywheel side of the pump. The
motor nameplate will show wiring information for
counterclockwise rotation.
The proper direction is very important. The direction
of rotation of 3 phase motors can be reversed by
interchanging any two motor-line leads. For single phase
motors, refer to the motor nameplate.

Improperly grounded electrical components are shock hazards. Make sure all the
components are properly grounded to prevent death or serious injury.
