NOTES:
1. WIRE AND GROUND IN ACCORDANCE WITH NEC OR CEC, AND ALL APPLICABLE
LOCAL CODES.
2. Motor wires MUST be run in a separate steel conduit away from control wiring and incoming AC
power wiring.
3. Do not install contactors between the drive and the motor without consulting AC Technology for
more information. Failure to do so may result in drive damage.
4. Use only UL and CSA listed and approved wire.
5. Minimum wire voltage ratings: 300 V for 120, 208 and 240 Vac systems, and 600 V for 400,
480, and 590 Vac systems.
6. Wire gauge must be based on a minimum of 125% of the rated input/output current of the drive,
and a minimum 75°C insulation rating. Use copper wire only.
7. Strip off 0.20 to 0.25 inches of insulation for input power, output power, and DC Bus wiring.
