All basic interconnections (using the Digital Operator) are shown in Figures 1-3 and 1-4.

Complete wire interconnections according to Table 1-2, Figure 1-3 and Figure 1-4. Be sure to
observe the following:
• Use 600V vinyl-sheathed wire or equivalent. Wire size and type should be determined by local
electrical 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 when connecting 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. Attach ground
wire solidly to motor frame and to drive’s ground terminal.
• When using armored or shielded cable for connection between drive and motor, solidly connect
armor 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 in
a separate conduit from other power wiring. If lead length must exceed this distance, reduce
carrier frequency (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 wire
gauge. Install connectors using the correct crimp tool recommended by the connector
manufacturer.
