Wiring Method
WARNING
Cautions when wiring
Wire so that the indentation shape on the ferrule terminal caused by the crimping tool
comes to the opposite side of the white release button on the terminal block, as shown
in the figure below.
Cautions when attaching twin ferrule terminals
When attaching twin ferrule terminals onto the cable with a crimping tool, crimp so that
the indentation is formed at the correct position on the ferrule terminal by the crimping
tool. If the ferrule terminal is crimped in the wrong direction, the ferrule terminal
sometimes cannot be wired or this makes it difficult to remove the wiring.
Cautions when removing wiring
In the event that wiring cannot be drawn out, do not exert unnecessary force to draw out
the wiring. Rotate the cable to change the orientation of the ferrule terminal while
pressing in the white release button using a flat-bladed screwdriver (tip width 2.0 to 2.5
mm), and then try drawing out the wiring again. When twin ferrules are used in the
power supply wiring, turn the cables within the range of possible movement as they
interfere with adjacent terminals. Also, wiring may get caught on the terminal block and
cannot be drawn out if an attempt is made to draw out the wiring before the white
release button has been fully pressed in with a flat-bladed screwdriver.
Do not exert a force of 100 N or more on the white release button. Doing so might
damage the device.
