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.
