1-6The Drive leaves the factory with all parameters set for 2-Wire external reference control. Figure 1-5must be used for all external connections.To use the Drive in a 3-Wire application, drive parameters n001, n003, and n004 must bereprogrammed, using the Digital Operator. Figure 1-6 must then be used for all external connections.IMPORTANTWhen a cable gland is used for water and dust tight type (NEMA type 4X/12) models, observe thefollowing:• Use multi-core cable for cable gland. (If more than one cable is inserted into one cable gland,a gap is created and may cause leakage.)• Seal the cable gland with a gasket without fail. (A gasket is attached to the recommendedcable gland.)A. Main Circuit Input /Output WiringComplete wire interconnections according to Table 1-2, Figure 1-5 thru Figure 1-7. Be sure toobserve the following:• Use 600V vinyl-sheathed wire or equivalent. Wire size and type should be determined by localelectrical codes.• Avoid routing power wiring near equipment sensitive to electrical noise.• Avoid running input and output wiring in the same conduit.• NEVER connect AC main power to output terminals T1(U), T2(V), and T3(W).• NEVER allow wire leads to contact metal surfaces. Short-circuit may result.• NEVER connect power factor correction capacitors to the drive output. Consult Yaskawa whenconnecting noise filters to the drive output.• WIRE SIZING MUST BE SUITABLE FOR CLASS I CIRCUITS.• When connecting motor to drive’s output terminals, include a separate ground wire. Attachground wire solidly to motor frame and to drive’s ground terminal .• When using armored or shielded cable for connection between drive and motor, solidly connectarmor or shield to motor frame, and to drive’s ground terminal .• Motor lead length should NOT EXCEED 164 feet (50 meters), and motor wiring should be run ina separate conduit from the power wiring. If lead length must exceed this distance, reduce carrierfrequency (see paragraph 5.8) and consult factory for proper installation procedures.• Use UL listed closed loop connectors or CSA certified ring connectors sized for the selected wiregauge. Install connectors using the correct crimp tool recommended by the connector manufacturer.1.4 ELECTRICAL INSTALLATIONModel CIMR-V7* MV Dimensions in inches (mm)Qty-Dia20P1 A00120P2 A002 3-0.89 DIA20P4 A003 (3-Ø 22.6)20P7 A00521P5 A00822P2 A01123P7 A01725P5 A025 3-1.38 DIA27P5 A033 (3-Ø 35)40P2 B00140P4 B00240P7 B00341P5 B00542P2 –43P7 B00945P5 B015 3-1.38 DIA47P5 – (3-Ø 35)Cable Gland Mounting Hole3-1.06 DIA(3-Ø 26.8)3-0.89 DIA(3-Ø 22.6)3-1.06 DIA(3-Ø 26.8)
