Connect Opener Power Cables; Connect The Transformer - Nortek Security & Control Mighty Mule HD272 Installation Manual

Connect Opener Power Cables

Step 1
Bring FIRST power cable into the control box through a strain relief slot,
leaving enough wire to reach the FIRST OPR. terminal block.
Insert the individual power cable wires into appropriate terminals on the FIRST
OPR. terminal block (white to WHT; green to GRN; red to RED; black to BLK).
Tighten the set screws. A dab of petroleum jelly on each terminal will help
prevent corrosion.
Step 2
Pull the 36' second opener power cable through the PVC conduit and secure in
the driveway slot/trench (see page 6 and page 16).
Step 3
Insert the SECOND power cable into a strain relief slot. Bring power cable into
the control box through a strain relief slot, leaving enough wire to reach the
SECOND OPR. terminal block.
Insert the individual power cable wires into appropriate terminals on the
SECOND OPR. terminal block (white to WHT; green to GRN; red to RED;
black to BLK). Tighten the set screws. A dab of petroleum jelly on each terminal
will help prevent corrosion.

Connect the Transformer

(*Solar Instructions on page 23)
NEVER USE TRANSFORMER AND SOLAR PANEL(S) AT THE SAME TIME!
IMPORTANT INFORMATION ABOUT LOW VOLTAGE WIRE:
• The only wire acceptable for use with NSC products is 16 gauge multi-stranded, low voltage, direct burial wire. This
particular gauge enables the transformer to provide an adequate charge through the control board to the battery at
distances up to 1000'.
• DO NOT use telephone wire or solid core wire. Unlike multi-stranded wire, these types of wire are inadequate for use
with your gate opener system.
• NEVER splice wires together. Splicing permits corrosion and seriously degrades the wire's ability to carry an adequate
current.
Step 1
Make sure the power switch is OFF.
Step 2
Select the electrical outlet where you will plug the transformer. Measure the
distance from this outlet to the control box following the path where the wire
will be laid. After you have measured how much wire is needed, cut the wire to
the appropriate length (up to 1000').

Lay the measured length of low voltage wire
in a trench following a path from the selected
electrical outlet to the control box. Wires coming
up from the ground should be run through PVC
conduit to protect them from lawn mower blades,
weed eaters, and grazing animals. Be sure to bury
the wire laid in the trench.
