NOTICE: Insulate shields with tape or shrink tubing to prevent contact with other signal lines and equipment. Improper wiring practices
could result in drive or equipment malfunction due to short circuit.
Wire the control circuit only after terminals have been properly grounded and main circuit wiring is complete. Refer to
Figure 3.21 for details. Prepare the ends of the control circuit wiring as shown in Figure 3.22 . Refer to Wire Size and
Torque Specifications on page 75 .
WARNING! Do not tighten screws beyond the specified tightening torque. Failure to comply may result in erroneous operation, damage
the terminal block, or cause injury due to fire from overheating of loose electrical connections.
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 Figure 3.21 .
Figure 3.20
Figure 3.21 Terminal Board Wiring Guide
When connecting control wires to the terminals, use shielded twisted-pair wires (treating wire ends as shown in
Figure 3.22 and connect the shield to the ground terminal (E [G]) of the drive.

NOTICE: Do not exceed 50 meters (164 ft.) for the control line between the drive and the operator when using an analog signal from a
remote source to supply the frequency reference. Failure to comply could result in poor system performance.
