Verifying the Drive’s Watts
Loss Rating
When mounting the drive inside of an enclosure, you should 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). Ensure 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:The vented top cover for the PowerFlex 700L Frame 3A and 3B
complete drives should be installed before routing input wiring.
Refer to 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 (e.g., NEC/CEC). Signal wiring, control
wiring, and power wiring must be routed in separate conduits to prevent
interference with drive operation. Use grommets, when hubs are not
provided, to guard against wire chafing.
Do not route more than three sets of motor leads through a single conduit.
This will minimize cross-talk that could 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 communications 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 could
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, all drives using this conduit should be disabled to
eliminate the possible shock hazard from cross-coupled motor
leads. Failure to observe these precautions could result in bodily
injury.
