HOW TO CONNECT WIRING TO THE TERMINALS

A.  For solid core wiring (or F-cable)(Fig.24A)

(1) Cut the wire with a wire cutter or wire-cutting pliers, then strip the insulation to about 25mm of the
     exposed solid wire.
(2) Using a screwdriver, remove the terminal screw(s) on the terminal board.
(3) Using pliers, bend the solid wire to form a loop suitable for the terminal screw.
(4) Shape the loop wire properly, place it on the terminal board and tighten securely with the terminal
     screw using a screw driver.

B.  For strand wiring(Fig.24B)

(1) Cut the wire with a wire cutter or wire-cutting pliers, then strip the insulation to about 10mm of the
     exposed strand wiring.
(2) Using a screwdriver, remove the terminal screw(s)on the terminal board.
(3) Using a round terminal fastener or pliers, securely clamp a round terminal to each stripped wire end.
(4) Position the round terminal wire, and replace and tighten the terminal screw using a screw driver.
