WARNING
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 screened cables or
metal conduits could result in death or serious injury.
•Run output motor cables separately, or
•Use screened cables or metal conduits
•Comply with local and national electrical codes
for cable sizes. For maximum wire sizes see
chapter 8.1 Electrical Data.
•Follow motor manufacturer wiring requirements.
•Motor wiring knockouts or access panels are
provided at the base of IP21 (NEMA1/12) and
higher units.
•Do not wire a starting or pole-changing device
(e.g. Dahlander motor or slip ring induction
motor) between the frequency converter and the
motor.
Procedure
1. Strip a section of the outer cable insulation.
2. Position the stripped wire under the cable clamp
to establish mechanical xation and electrical
contact between the cable screen and ground.
3. Connect the ground wire to the nearest
grounding terminal in accordance with the
grounding instructions provided in
chapter 4.3 Grounding, see Figure 4.5.
4. Connect the 3-phase motor wiring to terminals
96 (U), 97 (V), and 98 (W), see Figure 4.5.
5. Tighten the terminals in accordance with the
information provided in chapter 8.7 Connection
Tightening Torques.
