6.3 Installing Output Wiring from the Drive Output
Terminals to the Motor
Important: The total motor lead length must not exceed 76 meters (250 feet).
Use the following steps to connect the AC output power wiring from the drive to the
motor:
Step 1. Wire the three-phase AC output power motor leads by routing them as shown
in figures 4.1, 4.2, or 4.3. Tables 3.3, 3.4, and 3.5 contain the recommended
power wiring sizes.
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.
Step 2. Connect the three-phase AC power motor leads to the appropriate output
terminals. Figures 4.1, 4.2, and 4.3 show the locations of the output power
terminals.
Step 3. Tighten the three-phase AC output power terminals to the proper torque as
shown in table 5.1.
!
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 these precautions 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.
