INSTALLATION INSTRUCTIONS (CONTINUED)
Grounding
Make sure all the components are properly
grounded to prevent death or serious injury.
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.
Refer to the following wiring diagrams for electrical
installation:
1. Rewire the motor leads for 460 volt per motor data
plate.
2. Install the 460 volt conversion kit. Both the coil and
the thermal overload elements in the magnetic starter
must be changed (see below chart for part number).
