WARNING! 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.
