INSTALLATION INSTRUCTIONS (CONTINUED)
Wiring
Wiring must be installed in accordance with National Electrical Code and local codes and standards that
have been set up covering electrical apparatus and wiring. These should be consulted and local ordinances
observed. Be certain that adequate wire sizes are used, and that:
• Service is of adequate ampere rating.
• The supply line has the same electrical
characteristics (voltage, cycles and phase) as
the motor. Refer to motor name plate for
electrical ratings and specifications.
• The line wire is the proper size and that no
other equipment is operated from the same
line. The chart gives minimum recommended
wire sizes for compressor installations.
• Use a slow blow fuse type T or a 240 Volt
double pole circuit breaker.
Make sure voltage is correct with the motor wiring.
NOTE: If using 208 volts single phase, make sure the motor name plate states it is rated for 208 volts single
phase. 230 volt single phase motors do not work on 208 volts unless they have the 208 volt rating.
Recommended wire sizes may be larger than the minimum set up by local ordinances. If so, the larger size
wire should be used to prevent excessive line voltage drop. The additional wire cost is very small compared
with the cost of repairing or replacing a motor electrically "starved" by the use of supply wires which are too
small.

WIRING INSTRUCTIONS

1. Inspect the source wiring before continuing with installation. Confirm voltage with volt meter line-to-
ground (see Figure 7).
Volt meter should read 120 Volts.

Improperly grounded motors are shock hazards. Make sure all the equipment is properly
grounded.
All wiring and electrical connections must be performed by a qualified electrician
familiar with induction motor controls. Installations must be in accordance with local and
national codes.
Overheating, short circuiting and fire damage will result from inadequate wiring.
Disconnect, tag and lock out power source, then release all pressure from the system before
attempting to install, service, relocate or perform any maintenance.
Damage to the motor from improper electrical voltage or connection will void the warranty.
