4.7 ELECTRICAL PREPARATION

Interior electrical wiring is performed at the factory.
Required customer wiring is minimal, but should be
by a qualified electrician in compliance with OSHA,
National Electrical Code, and any other applicable
state or local electrical code concerning isolation
switches, fuse disconnects, etc. Sullair provides a
wiring diagram for use by the installer.
A few electrical checks should be made to help
assure that the first start-up will be trouble free.
Lethal shock hazard inside.
Disconnect all power at source, before opening
or servicing starter or control panel.
1. Check incoming voltage. Be sure that the incom-
ing voltage is the same voltage that the com-
pressor was wired for.

2. Check starter and overload heater sizes (see
Electrical Parts in Parts Manual).
3. Check all electrical connections for tightness.
4. "DRY RUN" the electrical controls by disconnect-
ing the three (3) motor leads from the starter.
Pull out the EMERGENCY STOP button on the
control panel and press
Since some solid state starters have built-in power moni-
toring, a dry run will only indicate compressor overload
when machine has this type of starter.
5. Reconnect the three (3) motor leads and jog the
motor for a direction of rotation check, as explained
in Section 4.8.

4.8 MOTOR ROTATION DIRECTION CHECK

After the electrical wiring has been done, it is nec-
essary to check the direction of the motor rotation.
With the control system in MANUAL mode, press
the and pads in succession to bump start
the compressor. When looking at the motor from the
end opposite the compressor unit, the shaft should
be turning clockwise on all gear driven models, and
counterclockwise on direct drive models.
motor shaft is not turning in the proper direction,
disconnect the power to the starter and exchange
any two of the three power input leads, then re-
check rotation. A "Direction of Rotation" decal is
located on the coupling guard between the motor
and compressor to show proper motor/compressor
rotation.
