To reduce the risk of electric shock, your garage door
opener has a grounding type plug with a third grounding

the plug doesn't fit into the outlet you have, contact a
qualified electrician to install the proper outlet.

To make a permanent connection through the 7/8" hole
in the back of the motor unit (according to local code):
• Remove the opener from the torsion bar, remove cover
screws and set the cover aside.
• Remove the attached green ground terminal.
• Cut black and white wires and strip away 1/2"
(1.3 cm) of insulation, 3" (7.6 cm) before spade
terminals.
• Remove the power cord from unit.
• Install a 90 o conduit or flex cable adapter to the 7/8"
hole. Reinstall opener to torsion bar.
• Run wires through conduit, cut to proper length and
strip insulation.
• Attach with wire nuts provided. Wire nuts to be
installed as indicated in Figure 1.
• Properly secure wire under plastic ties so that wire
does not come in contact with moving parts.
