Control Wire Routing for the Drive
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. Note
that no wires are to be routed behind the drive. Use grommets, when hubs are not
provided, to guard against wire chafing. Figures 4.1, 4.2, and 4.3 show the wire
routing, grounding terminal, and power terminal strips of the GV3000/SE Bookshelf
drives.
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.
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: 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.
ATTENTION: The user is responsible for conforming with all applicable
local, national, and international codes. Failure to observe this precaution
!
could result in damage to, or destruction of, the equipment.
On 2 to 15 A drives, the grounding terminal is located on the drive faceplate (refer to
figure 4.1). On 24 to 43 A drives, you will need to remove the drive faceplate and cover
to access the grounding terminal (refer to figure 4.2 or 4.3).
Use the following steps to ground the drive:
Step 1. Run a suitable equipment grounding conductor unbroken from the drive's
ground terminal to the motor's ground terminal and then to earth ground. See
figures 4.1, 4.2, or 4.3.
Step 2. Connect a suitable grounding conductor to the motor frame, the remote
control station (if used), and the transformer. Run each conductor unbroken
to earth ground.
When adding more than one grounding conductor wire to a single chassis
ground, twist the conductors together.
Step 3. 24 to 43 A drives only: Reattach the front panel and then the cover.
