Wiring Procedure

This section describes the proper procedures and preparations for wiring the terminal board.
WARNING! Electrical Shock Hazard. Do not remove covers or touch the circuit boards while the power is
on. Failure to comply could result in death or serious injury.
NOTICE: Separate control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, B1, B2, U/T1,
V/T2, W/T3, -, +1, +2) and other high-power lines. Improper wiring practices could result in drive malfunction
due to electrical interference.
NOTICE: Separate wiring for digital output terminals MA, MB and MC from wiring to other control circuit
lines. Improper wiring practices could result in drive or equipment malfunction or nuisance trips.
NOTICE: Use a class 2 power supply (UL standard) when connecting to the control terminals. Improper
application of peripheral devices could result in drive performance degradation due to improper power
supply.

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.
NOTICE: Connect the shield of shielded cable to the appropriate ground terminal. Improper equipment
grounding could result in drive or equipment malfunction or nuisance trips.
Wire the terminal board using Figure 3.13 as a guide (control circuit terminal block). Be
sure to prepare the ends of the control circuit wiring as shown in Figure 3.14. Refer to Wire
Gauges and Tightening Torque on page 33 for tightening torque specifications.
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.
