Notes on Wiring the Main Circuit Terminal Block
•
Use copper wire. Do not use alumnium or other non-copper wire.
•
Remove all unwanted objects that are near the terminal block connections.
•
Remove the insulation from the connection wires to the wire stripping lengths shown in the manual.
•
Do not use bent or crushed wires. Remove the damaged end of the wire before you use it.
•
Do not solder stranded wire.
•
If you use stranded wire, make sure that all of the wire strands are in the connection. Also, do not twist the
stranded wire too much.
•
Put the wire all the way into the terminal block. Remove the insulation from the wire to the recommended wire
stripping length to fit the wire with insulation in the plastic housing.
•
The tightening torque is different for different terminals. Tighten the screws to the specified tightening torque.
•
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.
•
If you use power tools to tighten the terminal screws, use a low speed setting (300 to 400 r/min).
•
Users can purchase wiring tools from Yaskawa. Contact Yaskawa or your nearest sales representative for more
information.
•
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 9.2 Permitted Angle
•
Put the bit all the way into the hex socket to tighten the hex socket cap screw.
•
When tightening straight-edge screws, hold the tip of the screwdriver in the center of the screw head. Do not let
the tip of the screwdriver slip out from the groove of the screw.
Figure 9.3 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.
•
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
for an example.
