Drive Wiring

Publication 1302-5.0 — January, 1998

Use the following steps to connect AC output power wiring from the
Drive to the motor:

Step 1. Wire the AC output power leads by routing them according

to the type of enclosure. See Figures 4.1 and 4.2. See
Table 3.B for recommended wire sizes.

!

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 which 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 possilble shock
hazard caused by induced voltages. 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.

Step 2. Connect the AC output power motor leads to terminals U, V

and W on the power terminal strip.

Step 3. Tighten terminals U, V, and W to the proper torque as

shown in Table 3.D.

Use the following steps to ground the Drive:

!

ATTENTION: You are responsible for conforming
with all applicable local, national and international
codes when grounding the Drive. Failure to observe
precautions and meet code could result in equipment
damage or personal injury.

Step 1. Remove the Drive’s cover.

Step 2. Run a suitable equipment grounding conductor unbroken

from the Drive’s ground terminal to the motor’s ground
terminal and then to earth ground. Refer to Figures 4.1,
4.2 and 5.1.

Step 3. Run a suitable grounding connector to the motor frame and

transformer (if used).

Step 4. Re–attach the Drive’s cover
