Drive Installation Chapter 2
Dimension drawings can be obtained by contacting the local Rockwell
Automation Sales office. The equipment does not require rear access for
servicing.
(E) Allowance must be made for the stream of cooling air which exits the drive
at the top. The flow of cooling air into and out the drive must be kept clear
and uninhibited.
(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 km (9.3 miles) 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.
.
Installation When the drive has been placed at its installation area, the lag bolts that fasten
the shipping skid to the drive must be removed. The drive is moved off the
shipping skid and the shipping skid can be discarded.
Position the drive in its desired location. Verify that the drive is on a level surface
and that the position of the drive will be vertical when the anchor bolts are
installed.
ATTENTION: 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.
