8.5 Replace the Drive
318 YASKAWA SIEPC71061753C GA500 Technical Manual
• Wire gauges on the drive you are replacing may not match the wire gauge ranges on your new drive. Refer to
the drive manuals for correct wire sizes.
• 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.
Figure 8.17 Permitted Angle
• 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.
Figure 8.18 Tightening Slotted Screws
• 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
Figure 8.19 for an example.
