• Use a torque driver, torque ratchet, or torque wrench for the screws. A slotted driver or a hex tool will be necessary
to wire the screw clamp terminal. Use applicable tools as specified by the recommended conditions in the product
manual.
• Users can purchase wiring tools from Yaskawa. Contact Yaskawa or your nearest sales representative for more
information.
• Wire gauges on the drive you are replacing may not match the wire gauge ranges on your new drive. Contact
Yaskawa or your nearest sales representative for more information about the connection procedures.
• Do not tighten the terminal screws at an angle of 5 degrees or more. Failure to obey can cause damage to the
terminal screws.
If you damage a terminal screw, contact Yaskawa or your nearest sales representative.

• Put the bit all the way into the hex socket to tighten the hex socket cap screw.
• When you tighten slotted screws, hold the straight-edge screwdriver perpendicularly to the screw. Make sure that
you align the end of the straight-edge screwdriver with the screw groove.

• 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.
• Do not let strain on the wiring cause damage. Use a strain relief near the wiring to release the tension. Refer to
