Installation (Continued)
GroundinG
Improperly grounded electrical
components are shock hazards.
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�
Motors used on CE7000, CE8000 and CE9000 Series air
compressors do not have built-in overload protection� A
magnetic starter is required� All CE Series compressors, except
models CE8000 and CE8002, include a magnetic starter� Refer to
the following wiring diagrams for electrical installation:
Shop Air Series Models - Figures 6 or 7
Automotive Series Models - Figures 8 or 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�
Shop Air Series Models
1� Rewire the motor leads for 460 volt per motor data plate�
2� Install the 460 volt conversion kit provided with the unit�
Both the coil and the thermal overload elements in the
magnetic starter must be changed (see Figure 11)�
Automotive Series Models
1� Rewire the motor leads for 460 volt per motor data plate�
2� Install the three thermal overload elements provided in the
conversion kit (see Figure 12)� The coil in the Automotive
Series models operates on 120 volts and does not have to be
changed�
