4. Tighten the nut to the specified torque.
Figure 3.32 Tighten the Terminal Block Nut
5. Examine the signal from the wired terminal and use a diagonal-cutting pliers to remove areas of the wiring
cover cutaway section.
Cut the areas shown in Figure 3.33.
A - Cutaway sections B - Use a diagonal-cutting pliers to clip
this area.
Figure 3.33 Clip the Cutaway Section of the Wiring Cover
Note:
• Different drive models have different wiring covers.
• Remove only the areas from the wiring cover that apply to the wired terminal. If you remove areas that do not apply to the wired
terminals, the drive will not keep its IP20 protective level.
• Tightly hold the cutaway section when you remove pieces of 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.
6. Attach the wiring cover and terminal block cover to their initial positions and tighten the screws on the terminal
block cover.

7. Put the terminal cover back in its initial position.
