2. Examine the signal from the wired terminal and use a diagonal-cutting pliers to remove areas of the wiring
cover cutaway section.
For details, refer to Cutaway Section of the Wiring Cover on page 111.
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
terminal, the drive will not keep its IP20 protective level.
• Make sure that you hold the cutaway section tightly 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.
• If you use the wiring cover correctly, but you use wires that are not specified by Yaskawa, the drive will not necessarily keep its
IP20 protective level. Contact Yaskawa or your nearest sales representative for more information.
• 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. If you use the applicable gauge for the electrical wires, you must attach the
wiring cover.
