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
l
removing cover to establish permanent wiring connection.
Garage door installation and wiring MUST be in compliance with ALL local electrical and
l
building codes.
NEVER use an extension cord, 2-wire adapter, or change plug in ANY way to make it fit
l
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.
THERE ARE TWO OPTIONS FOR CONNECTING POWER:
1. Plug in the garage door opener into a
grounded outlet.
2. DO NOT run garage door opener at this
time.

permanent connection through the 7/8 inch hole in the top of the motor unit (according to local code):

and disconnect power to circuit.
2. Remove the garage door opener cover and set
