• Wire gauges on existing drive models to be replaced may not match wire gauge ranges on new drives. Contact
Yaskawa or your nearest sales representative for wire gauges that you can and cannot use.
• Do not tighten the terminal screws at an angle of 5 degrees or more.
Figure 4.19 Permitted Angle
• Put the bit all the way into the hex socket to tighten the hex socket cap screw.

• After you connect the wires to the terminal block, lightly pull on the wires to make sure that they do not come
out of the terminals.
• Remove the correct section of the wiring cover to make wiring easier.
• Regularly tighten loose terminal block screws to their specified tightening torques.
• Do not let strain on the wiring cause damage. Use a strain relief near the wiring to release the tension. Refer to
Figure 4.21 for an example.
