How to connect wiring to the terminal
■ For stranded wiring
(1) Cut the wire end with cutting pliers,
then strip the insulation to expose
the stranded wiring about 10 mm and
tightly twist the wire ends. (Fig. 4-7)
(2) Using a Phillips head screwdriver,
remove the terminal screw(s) on the
terminal plate.
(3) Using a ring connector fastener or
pliers, securely clamp each stripped
wire end with a ring pressure terminal.
(4) Place the ring pressure terminal,
and replace and tighten the removed
terminal screw using a screwdriver.

■ Examples of shield wires
(1) Remove cable coat not to scratch braided shield. (Fig. 4-9)
(2) Unbraid the braided shield carefully and twist the
unbraided shield wires tightly together. Insulate the shield
wires by covering them with an insulation tube or wrapping
insulation tape around them. (Fig. 4-10)
(3) Remove coat of signal wire. (Fig. 4-11)
(4) Attach ring pressure terminals to the signal wires and the
shield wires insulated in Step (2). (Fig. 4-12)
