Mounting the Drive, Grounding, and Determining Wire Routing Locations 3-15
3.2 Mounting the Drive
Refer to figures 3.4, 3.5, 3.6 and 3.7 for drive mounting dimensions.
Attach the drive to the vertical surface using the mounting holes provided.
Note: Drive dimension mounting hole centers are located on rear of drive for
reference.
3.2.1 Verifying the Drive’s Watts Loss Rating
When mounting the drive inside another enclosure, determine the watts loss rating of
the drive from tables 2.1 through 2.6. This table lists the typical full load power loss
watts value at a carrier frequency of 4 kHz.
3.3 Routing Input, Motor Output, Ground, and Control
Wiring for the Drive
All wiring must be installed in conformance with applicable local, national and
international codes, such as NEC/CEC. Signal wiring, control wiring and power wiring
must be routed in separate conduits to prevent interference with drive operation.
Note that no wires are to be routed behind the drive. Use grommets, when hubs are
not provided, to guard against wire chaffing.
Figures 3.8 and 3.9 show the wire routing, grounding terminal and power terminal
blocks of the GV6000 AC drives.
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.
!
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.
