4.9 Connecting the Motor
W A R N I N G
INDUCED VOLTAGE
Induced voltage from output motor cables that run together can charge equipment capacitors, even with the equipment turned
off and locked out/tagged out. Failure to run output motor cables separately or to use shielded cables could result in death or
serious injury.
Run output motor cables separately or use shielded cables.
Simultaneously lock out/tag out all the drives.
Run output motor cables separately or
Use shielded cables.
Comply with local and national electrical codes for cable sizes. For maximum wire sizes, see
.
Follow motor manufacturer wiring requirements.
Motor wiring knockouts or access panels are provided at the base of IP55 (NEMA 12) units.
Do not wire a starting or pole-changing device (for example a Dahlander motor or slip ring asynchronous motor) between the
drive and the motor.
4.9.1 Grounding the Cable Shield
Procedure
Strip a section of the outer cable insulation.
Position the stripped wire under the cable clamp to establish mechanical fixation and electrical contact between the cable
shield and ground.
