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 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).

DIRECTION OF ROTATION
NOTE: IMPROPER ROTATION WILL RESULT IN FAILURE OF
COMPRESSOR.
The direction of rotation must be counterclockwise (as shown
by the arrow on the air end in Figure 6) while facing the flywheel
side of the pump.
The direction of rotation of 3 phase motors can be reversed by
interchanging any two motor-line leads.
CHECKING ROTATION DIRECTION
Figure 6 - Direction of rotation
ROTATION DIRECTION: rotating to the left (counterclockwise)
looking at the shaft.
The rotation direction of the screw
compressor system must be checked
during initial start-up and each time changes are made to
the electrical supply line of the electric motor drive. For this
purpose, switch on the drive motor briefl y and then switch off
again immediately. ROTATION FOR MORE THAN 2 SECONDS IN
THE WRONG ROTATION DIRECTION WILL DESTROY THE SCREW
COMPRESSOR. If necessary, reverse the connections of the
connecting cable.
