insulation to expose the stranded wiring about 10
mm and tightly twist the wire ends. (Fig. 4-5)
(2) Using a Phillips head screwdriver, remove the ter-
minal 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 screw-
driver. (Fig. 4-6)
Loose wiring may cause
the terminal to overheat or
result in unit malfunction.
A fire hazard may also
exist. Therefore, ensure
that all wiring is tightly
connected.
