‹ Periodic Maintenance Safety
DANGER! Do not change wiring, remove covers, connectors or options cards, or attempt to service the drive with power applied to the
drive. Disconnect all power to the drive, and lock out the power source. After shutting off the power wait for at least the amount of time
specified on the drive front cover safety label. Measure the DC bus voltage for unsafe voltages to confirm safe level before servicing to
prevent electric shock. The internal capacitor remains charged even after the power supply is turned off. Failure to comply will result in
serious injury or death from electric shock.
WARNING! Burn Hazard. Because the heatsink can get very hot during operation, take proper precautions to prevent burns. When
replacing the cooling fan, shut off the power and wait at least 15 minutes to be sure that the heatsink has cooled down. Failure to
comply may cause burn injury to personnel.
‹ Motor Application Safety
NOTICE: Equipment Damage. A motor connected to a PWM drive may operate at a higher temperature than a utility-fed motor and the
operating speed range may reduce motor cooling capacity. Ensure that the motor is suitable for drive duty and/or the motor service
factor is adequate to accommodate the additional heating with the intended operating conditions.
NOTICE: Insulation Tolerance. Consider motor voltage tolerance levels and motor insulation in applications with an input voltage of
over 440 V or particularly long wiring distances.
„ Audible Noise
The audible noise of the motor varies based on the carrier frequency setting. However, drive current derating may be
required. When using a high carrier frequency, audible noise from the motor is comparable to the motor noise generated
when running from line power.
Do not expose the drive to halogen group disinfectants.
Failure to comply may cause damage to the electrical components in the drive.
Do not pack the drive in wooden materials that have been fumigated or sterilized.
Do not sterilize the entire package after the product is packed.
Never steam clean the drive.
During transport, keep the drive from coming into contact with salts, fluorine, bromine, phthalate ester, and other such
harmful chemicals.
