Read these notes before you wire the main circuit terminal block.
| Warning |
|
Fire Hazard
Remove the insulation from the connection wires to the wire stripping lengths shown in the manual.
If the stripping length is incorrect, the connection can cause a fire.
|
| Warning |
|
Fire Hazard
Do not use bent or crushed wires. Remove the damaged end of the wire before you use it.
Incorrect connections can cause death or serious injury from fire.
|
| Warning |
|
Fire Hazard
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.
Incorrect connections can cause death or serious injury from fire.
|
| Notice |
|
If you use power tools to tighten the terminal screws, use a low speed setting (300 min-1 (r/min) to 400 min-1 (r/min)).
High speeds can cause damage to the terminal screws.
|
-
Use UL-Listed, vinyl-coated insulated copper wires for operation with a continuous maximum permitted temperature of 75 °C at 600 V.
-
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 solder stranded wire. Soldered wire connections can become loose over time and cause unsatisfactory drive performance.
-
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.
-
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.
Figure 1. 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 2. 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 3 for an example.
