The equipment must be kept clean. Dust in the equipment
decreases system reliability and inhibits cooling.
(I)
Power cable lengths to the motor are virtually unlimited due to
the near sinusoidal voltage and current waveforms. Unlike
voltage source drives, there are no capacitive coupling, dv/dt,
or peak voltage issues that can damage the motor insulation
system. The topology utilized in the PowerFlex 7000 medium
voltage AC drive does not produce dv/dt or peak voltage
problems, and has been tested with motors located up to 15
kilometers from the drive.
(J)
Only personnel familiar with the function of the drive should
have access to the equipment.
(K)
The drive is designed for front access and should be installed
with adequate and safe clearance to allow for total door
opening. The back of the unit may be placed against a wall
although some customers prefer back access also.
An incorrectly applied or installed drive can

result in component damage or a reduction in
product life. Ambient conditions not within
the specified ranges may result in
malfunction of the drive.
Generator Note:
Verify that the load is not turning due to the

process. A freewheeling motor can generate
voltage that will be back-fed to the equipment
being worked on.
