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.
