Fire Hazard. Tighten all terminal screws to the correct tightening torque.
Connections that are too loose or too tight can cause incorrect operation and damage to the drive.
Incorrect connections can also cause death or serious injury from fire.
Note:
• Use shielded, twisted-pair wires and ground the shield to the ground terminal of the drive. Incorrect
equipment grounding can cause drive or equipment malfunction from electrical interference.
• Do not use control circuit wiring that is longer than 50 m (164 ft) to supply the analog frequency reference
from a remote source. If the control circuit wiring is too long, it can cause unsatisfactory system
performance.
