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�

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�

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�
