NOTICE: Do not tighten screws beyond the specified tightening torque. Failure to comply may damage the terminal block.
NOTICE: Use shielded twisted-pair cables as indicated to prevent operating faults. Improper wiring practices could result in drive or
equipment malfunction due to electrical interference.
Connect control wires as shown in the following figure:

When setting the frequency by analog reference from an external potentiometer, use shielded twisted-pair wires and ground
the shield of twisted-pair wires to the ground terminal of the drive.
NOTICE: The analog signal lines between the drive and the operator station or peripheral equipment should not exceed 50 meters when
using an analog signal from a remote source to supply the frequency reference. Failure to comply could result in poor system performance.
