Motor connection
WARNING:
INDUCED VOLTAGE. Run output motor cables from multiple frequency converters
separately. Induced voltage from output motor cables run together can charge
equipment capacitors even with the equipment turned off and locked out. Failure to run
output motor cables separately could result in death or serious injury.
Be sure the following are adhered to:
• For maximum wire sizes see Power-dependent Specifications.
• Comply with local and national electrical codes
• Motor wiring knockouts or access panels are provided at the base of IP21 and higher
(NEMA 1/12) units
• Do not install power factor correction capacitors between the frequency converter
and the motor
• Do not wire a starting or pole-changing device between the frequency converter and
the motor
• Connect the 3–phase motor wiring to terminals 96 (U), 97 (V), and 98 (W)
• Ground the cable in accordance with grounding instructions provided
• Torque terminals in accordance with the informations provided in Connection
tightening torques.
• Follow motor manufacturer wiring requirements
