Wiring Procedure

This section describes the proper procedures and preparations for wiring the control terminals.
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 control terminals using Figure 3.13 as a guide. Prepare the ends of the control circuit
wiring as shown in Figure 3.14. Refer to Wire Size and Torque Specifications on page 55.
NOTICE: Do not tighten screws beyond the specified tightening torque. Failure to comply may damage the
terminal.
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:
