1. STRIP 1/2 IN. (13 MM)
FROM WIRES TO
BE ATTACHED AT
1/2 (13)
ONE TERMINAL.
2. TWIST WIRES
TOGETHER WITH
PLIERS (A MINIMUM
OF THREE TURNS).
3. CUT TWISTED END OF WIRES
TO 3/16 IN. (5 MM) BEFORE INSERTING
INTO TERMINAL AND TIGHTENING SCREW.
THEN PULL ON EACH WIRE IN ALL
TERMINALS TO CHECK FOR
GOOD MECHANICAL CONNECTION.
