Examine the signal from the wired terminal and use a diagonal-cutting pliers to remove areas of the wiring
cover cutaway section.
Note:
6-Phase/12-pulse drives (models: Txxx) do not have the wiring covers.
Cut the areas shown in Figure 5.45 .
A - Cutaway sections B - Use a diagonal-cutting pliers to clip this area.
Figure 5.45 Clip the Cutaway Section of the Wiring Cover
Note:
• Different drive models have different wiring cover shapes.
• Clip only the areas from the wiring cover that apply to the wired terminal. If you clip areas that do not apply to wired terminals,
the drive will not keep its IP20 protective level.
• When you clip pieces of the cutaway section, tightly hold the cutaway section. Pieces of the cutaway section can fly out and
cause injury.
• Make sure that the clipped section does not cause damage to the wires.
• Although the wiring cover is correct, if you use wires that are not specified by Yaskawa, the drive will not keep its IP20 protective
level.
• When you use the recommended gauge for the electrical wires, it is not necessary to attach the wiring cover of the main circuit
power input terminal and the drive output terminal. When you use the applicable gauge for the electrical wires, attach the wiring
cover.
