Rockwell Automation 7000 PowerFlex Medium Voltage AC Drive (B Frame) - Classic Control - Manual (Page 41)

2-6 Drive Installation
7000-UM150I-EN-P – June 2013 7000 “B” Frame
(F) The room in which the equipment is located must be large
enough to accommodate the thermal losses of the equipment
since air conditioning may be required; the ambient
temperature must not exceed that for which the equipment is
rated. The heat created by the drive is directly proportional to
the power of the motor being driven and the efficiency of
equipment within the room. If thermal load data is required
contact the Rockwell Automation Sales office.
(G) The area in which the drive is located should be free of radio
frequency interference such as encountered with some welding
units. This may cause erroneous fault conditions and shut
down the drive.
(H) 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 CSI-PWM topology utilized in the PowerFlex 7000
medium voltage AC drive 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. If back
access is desired, set drive 300 mm (12 inches) out from wall.

result in component damage or a reduction in
product life. Ambient conditions not within
the specified ranges may result in
malfunction of the drive.
