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 4 .
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 4 .
Table 4 - AC Output Power Terminal Block Specifications
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.
