Installation
This chapter shows how to mount the 1302 Drive and its external
components. Also shown are the entry areas for routing wiring in
and out of the Drive.
Attach the drive to the selected flat, vertical surface using the
mounting holes provided. Enclosure B and C Drives have four
mounting holes. In order to maintain a flat mounting surface and to
ensure that bolt tightness is maintained, use washers under the bolt
heads. Refer to Figures 3.1 and 3.2 for Drive mounting dimensions.
Use the following user-supplied mounting bolts and washers:
•
Enclosure B Drives: four M8 (5/16”)
•
Enclosure C Drives: four M8 (5/16”)
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. Do not route
wires behind the Drive. Use grommets when hubs are not provided
to guard against wire chafing. Figures 4.1 and 4.2 show the wire
routing, grounding terminal, and power terminal strips of the 1302
Drives.
!
ATTENTION: Do Not route signal and control wiring
in the same conduit with power wiring. This can cause
interference with Drive operation. Failure to observe
this precaution could result in damage to, or
destruction of, the equipment.
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, you must use
shielded cable. If possible, each conduit should contain only one set
of motor leads.
!
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.
