INDUCED VOLTAGE
Induced voltage from output motor cables that run together can charge equipment capacitors, even with the
equipment turned o and locked out. Failure to run output motor cables separately or use shielded cables could result
in death or serious injury.
•
Comply with local and national electrical codes for cable sizes. For maximum wire sizes, see chapter 9.1 Electrical
Data.

Motor wiring knockouts or access panels are provided on the pedestal of IP21/IP54 (Type 1/Type 12) units.
•
Do not wire a starting or pole-changing device (for example Dahlander motor or slip ring asynchronous motor)
between the drive and the motor.
Procedure
1. Strip a section of the outer cable insulation.
2. Establish mechanical xation and electrical contact between the cable shield and ground by positioning the
stripped wire under the cable clamp.
3. Connect the ground wire to the nearest grounding terminal in accordance with the grounding instructions
provided in chapter 5.6 Connecting to Ground.
4. Connect the 3-phase motor wiring to terminals 96 (U), 97 (V), and 98 (W), see Illustration 5.3.
5. Tighten the terminals in accordance with the information provided in chapter 9.10.1 Fastener Torque Ratings.
