4.0 MOUNTING THE DRIVE, GROUNDING, AND
FINDING WIRE ROUTING LOCATIONS
This chapter shows how to mountthe drive and properly ground it. Also shownare the conduit entry
areas where wiring is to be routed in and outof the drive.
4.1 Mounting the Drive
Attach the drive to the vertical surface selected using the four (4) mounting holes provided. In order
to maintain a flat mounting surface and to ensure that bolt tightness is maintained, use washers
under the bolt heads. Refer to figure 3.2 and table 3.2 for drive mounting dimensions. Use the
following user-supplied mounting bolts and washers:
@ 1-5HP drives: M6 (1/4"-20 )
e@ 7.5-10HP drives: M8 (5/16"-18 )
e@ 15-60HP drives: M8 or M10 (3/8"-16 )
e@ 60-150HP drives: M8 (3/8" -16)
4.1.1 Verifying the Drive's Watts Loss Rating
When mounting the drive inside of another enclosure, you should examine the watts loss rating of the
drive as shownin table 2.1. This table lists the typical full load power loss watts value under all
operating carrier frequencies. Ensure adequate ventilation is provided based on the drive's watts loss
rating.
4.2 Routing Input, Motor Output, Ground, and Control Wiring for the
Drive
All wiring should beinstalled in conformance with the NEC/CEC and applicable local codes. 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 4.1 through 4.6 showthe wire routing,
grounding terminal, and power terminalstrips of the GV3000 drives.
CAUTION: 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.
Note that in applications using GV3000 drives (75 HP and above), inducedelectrical noise may result
when the motor output leads from two or more drives are run together in the same conduit. It is
recommendedthat separate conduit be run from each drive to the motor it is operating.
