Output Power Wiring
Refer to the PowerFlex 40 User Manual for additional detailed information
about output power wiring recommendations and selection.
To connect AC output power wiring from the drive to the motor:
❏ 1. Wire the three-phase AC output power motor leads by routing them
according to the drive option type. Note that you must punch openings in
the option cabinet of the desired conduit size, following NEC and all
applicable local codes and standards. Power terminal block
specifications are listed in Table 1.C
.
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.
❏ 2. Connect the three-phase AC output power motor leads to terminals
U, V, W (T1, T2, T3) on the power terminal block located on the drive.
❏ 3. Tighten the three-phase AC output power terminals to the proper torque
according to drive type as shown in Table 1.C
.

!
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: 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.
