NOTICE: Do not tighten screws beyond the specified tightening torque. Failure to comply may result in erroneous operation, damage to the
terminal block, or cause a fire.
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.
Wire the control circuit only after terminals have been properly grounded and main circuit wiring is complete. Refer to
Terminal Board Wiring Guide on page 33 for details. Prepare the ends of the control circuit wiring as shown in Figure i.
20 . Refer to Wire Gauges on page 32 .
