Step 4
Insert the stripped power cable wires into the appropriate
terminals on the MASTER operator 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.
Tighten the set screws against the end of the wires. A
dab of petroleum jelly on each terminal will help prevent
corrosion.

Step 6
Strip approximately 3/16" of insulation from each wire
of the 40 foot power cable. Twist each exposed wire
tightly. Insert the second opener power cable upward
through the right strain relief (if necessary, loosen the
strain relief strain relief
sealing nut). Thread approximately 4" of wire into the
control box. Retighten strain relief (on the black sheath
of the power cable) until the power cable locks into
place.
Insert the stripped wires of the power cable into the
appropriate terminals on the SLAVE operator 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.
Tighten the set screws against the end of the wires.
Step 5
Review the Installation Overview illustration on page 11 before proceeding.
Cut a slot into the driveway to accommodate PVC conduit (not provided). The buried conduit will protect the 40 foot power
cable from automobile tires, lawn mower blades, weed eaters, and grazing animals. Pull the 40 foot second opener power
cable through the conduit and secure them into the slot in the driveway.
