WARNING
An upstream disconnect/protective device must be
provided as required by the National Electrical Code
®
(NEC
®
). Failure to follow this precaution may result in
death or severe injury.
WARNING
Before opening the SC9000 EP drive doors:
Open main disconnect switch on the SC9000 EP drive.
Wait a minimum of 5 (five) minutes after all the lights on
the keypad are off. This allows time for the DC bus
capacitors to discharge.
A hazard voltage may still remain in the DC bus
capacitors even if the power has been turned off. While
wearing proper PPE, open the doors to the drive. Locate
the yellow shorting stick and ensure metal end of stick is
grounded. Discharge both halves of DC bus utilizing
grounding studs on the rectifier.
Failure to follow the above precautions may cause death
or severe injury.
Cautions
CAUTION
Do not perform any meggar or voltage withstand tests on
any part of the SC9000 EP drive or its components. Improper
testing may result in damage.
CAUTION
Prior to any tests or measurements of the motor or the
motor cable, disconnect the motor cable at the SC9000 EP
output terminals (U, V, W) to avoid damaging the SC9000 EP
during motor or cable testing.
CAUTION
Do not touch any components on the circuit boards. Static
voltage discharge may damage the components.
CAUTION
Any electrical or mechanical modification to this equipment
without prior written consent of Eaton will void all warranties
and may result in a safety hazard in addition and voiding of
the UL listing.
CAUTION
Prevent foreign material such as wire clippings or metal
shavings from entering the drive enclosure, as this may
cause arcing damage and fire.
CAUTION
Install the SC9000 EP drive in a well-ventilated room that is
not subject to temperature extremes, high humidity, or
condensation, and avoid locations that are directly exposed
to sunlight, or have high concentrations of dust, corrosive
gas, explosive gas, inflammable gas, grinding fluid mist, etc.
Improper installation may result in a fire hazard.
Motor and Equipment Safety
CAUTION
Before starting the motor, check that the motor is mounted
properly and aligned with the driven equipment. Ensure that
starting the motor will not cause personal injury or damage
equipment connected to the motor.
CAUTION
Set the maximum motor speed (frequency) in the SC9000 EP
drive according to the requirements of the motor and the
equipment connected to it. Incorrect maximum frequency
settings can cause motor or equipment damage and personal
injury.
CAUTION
Before reversing the motor rotation direction, ensure that
this will not cause personal injury or equipment damage.
CAUTION
Make sure that no power correction capacitors are
connected to the SC9000 EP output or the motor terminals
to prevent SC9000 EP malfunction and potential damage.
CAUTION
Make sure that the SC9000 EP output terminals (U, V, W) are
not connected to the utility line power as severe damage to
the SC9000 EP may occur.
