Power
1 Connect Power
To prevent possible SERIOUS INJURY or DEATH
from electrocution or fire:
• Be sure power is NOT connected to the opener,
and disconnect power to circuit BEFORE
removing cover to establish permanent wiring
connection.
• Garage door installation and wiring MUST be in
compliance with ALL local electrical and building
codes.
• NEVER use an extension cord, 2-wire adapter, or
change plug in any way to make it fit outlet. Be
sure the opener is grounded.
To avoid installation difficulties, do not activate the garage door opener at this time.
To reduce the risk of electric shock, your garage door opener has a grounding type plug with a third grounding pin. This
plug will only fit into a grounding type outlet. If the plug doesn’t fit into your outlet, contact a qualified electrician to install
the proper outlet.

If permanent wiring is required by your local code, refer to the following procedure.
To make a permanent connection through the 7/8 inch hole in the top of the motor unit (according to local code):
Wiring through a filter board (8550 models manufactured before April 12, 2013):
1.1B Be sure power is NOT connected to the opener, and disconnect power to circuit.
1.2B Remove the garage door opener cover and set aside.
1.3B Remove the attached green ground terminal.
1.4B Cut black and white wires. Strip away 1/2 inch (1 cm) of insulation, 3 inches (7.5 cm) before spade terminals.
1.5B Remove the power cord from opener.
1.6B Install a conduit or flex cable adapter to the 7/8 inch hole.
1.7B Run wires through conduit, cut to proper length and strip insulation.
1.8B Attach with wire nuts provided. Attach the ground wire to the green ground screw. The opener must be
grounded.
1.9B Properly secure wire under plastic ties so that wire does not come in contact with moving parts.
1.10B Reinstall the cover. DO NOT run garage door opener at this time.
Wiring through a terminal block (8550 models manufactured after April 12, 2013 and all 8557 models):
