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.
(2) Using a Phillips head screwdriver, remove the terminal
screw(s) on the terminal board.
(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.
(3) Do not install inter-unit control wiring such as star branch wiring. Star branch wiring causes mis-address setting.
