3.9 Control Circuit Wiring
YASKAWA ELECTRIC SIEP C710616 27G YASKAWA AC Drive A1000 Technical Manual 85
Wire Size
Select appropriate wire type and gauges from Table 3.10. For simpler and more reliable wiring, use crimp ferrules on the
wire ends. Refer to Ferrule-Type Wire Terminals on page 85 for ferrule terminal types and sizes.
Table 3.10 Wire Gauges
Ferrule-Type Wire Terminals
YASKAWA recommends using CRIMPFOX 6, a crimping tool manufactured by PHOENIX CONTACT, to prepare wire
ends with insulated sleeves before connecting to the drive. See Table 3.11 for dimensions.

Wiring the Control Circuit Terminal
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, R1/L11, S1/L21, T1/L31, B1, B2, U/T1,
V/T2, W/T3, –, +1, +2, +3) and other high-power lines. Improper wiring practices could result in drive malfunction due to electrical
interference.
NOTICE: Separate wiring for output terminals MA, MB, MC, M1, and M2 to M6 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 circuit only after terminals have been properly grounded and main circuit wiring is complete. Refer to
Figure 3.24 and Figure 3.25 for details. Prepare the ends of the co
ntrol circuit wiring as shown in Figure 3.26. Refer to
Wire Size on page 85.
