Verifying the Drive’s Watts
Loss Rating
When mounting the drive inside of an enclosure, determine the watts loss
rating of the drive from
Table A.E on page A-6 . This table lists the typical
full load power loss watts value at 4 kHz (rated carrier frequency). Make
sure that the enclosure is adequately ventilated with 0…40 °C (32…105 °F)
ambient air based on the drive’s watts loss rating.
Installing the Vented Top
Cover
Important:
Install the vented top cover for PowerFlex 700L Frame 3A and
3B complete drives before routing input wiring. See the vented
top cover installation instructions, publication 20L-IN002, for
more information.
Determining Wire Routing
for Control, Ground, Drive
Input, and Motor Output
All wiring should be installed in conformance with the applicable local,
national, and international codes (for example, NEC/CEC). Signal wiring,
control wiring, and power wiring must be routed in separate conduits to
prevent interference with drive operation. When hubs are not provided, use
grommets to guard against wire chafing.
Do not route more than three sets of motor leads through a single conduit.
This minimizes cross-talk that can reduce the effectiveness of noise
reduction methods. If more than three drive/motor connections per conduit
are required, shielded cable must be used. If possible, each conduit should
contain only one set of motor leads.
Frame 3A Drives
Figure 3.17 shows the location of Frame 3A Input Filter Bay wire routing.
Figure 3.20 shows locations for Frame 3A Power Module control wire
routing, DPI communication ports/cable routing, and coolant connections.
Figure 3.18 shows locations of Frame 3A complete drive control, ground,
drive input, motor output, and coolant connections.
!
ATTENTION:
Do not route signal and control wiring with
power wiring in the same conduit. This can cause interference
with drive operation. Failure to observe this precaution can result
in damage to, or destruction of, the equipment.
!
ATTENTION: Unused wires in conduit must be grounded at
both ends to avoid a possible shock hazard caused by induced
voltages. Also, if a drive sharing a conduit is being serviced or
installed, disable all drives using this conduit to eliminate the
possible shock hazard from cross-coupled motor leads. Failure to
observe these precautions can result in bodily injury.
