Strip approximately 3/16" of insulation from each wire of
the opener power cable. Twist each exposed wire tightly
(there are seven [7] wires inside the power cable sheath).
Loosen sealing nut on strain relief hub at bottom of
control box. Insert power cable into control box through
strain relief. Thread approximately 6" of the power cable
into the control box and retighten sealing nut until the
power cable locks into place.
Step 16
Insert the stripped power cable wires into the
appropriate terminals on the OPENER terminal
block. The green wire should be inserted into the
GRN terminal, the blue wire into BLU, the orange
wire into ORG, black wire into BLK, and the red
wire into the RED terminal, white wire into WHT,
and brown wire into BRN.
Tighten the set screws against the end of the wires.
A dab of petroleum jelly on each terminal will help
prevent corrosion.
