Grounding
- Equipment must be properly grounded according to Section 250 of the National Electrical
Code.
Failure to properly ground the compressor package could result in controller
malfunction.
7.
Rotation
- Check for correct motor rotation
by jogging the motor. See “Machine Configuration
Menu
” in the Controller Operating and Service Manual. Compressor drive shaft rotation must be
clockwise, standing facing the compressor sheave on gear drive.
Operation with incorrect motor rotation can damage equipment and cause oil
eruption from the compressor inlet. When checking motor rotation, induce
minimum rotation (less than one revolution if possible). Never allow motor to
reach full speed.
Check t
he compressor unit’s direction of rotation every time the compressor is
reconnected to the power supply.

discharge pressure, set the controls to the desired load pressure. DO NOT EXCEED THE MAXIMUM
OPERATING PRESSURE ON THE COMPRESSOR NAMEPLATE. See
“Operational Settings” in the
Controller Operating and Service Manual.
Operation at excessive discharge air pressure can cause personal injury or
damage to equipment. Do not adjust the full discharge air pressure above the
maximum stamped on the unit nameplate.
