1 Connect Power

To prevent possible SERIOUS INJURY or DEATH from electrocution or fire:
Be sure power is NOT connected to the operator, and disconnect power to circuit BEFORE removing cover
l
to establish permanent wiring connection.
Door installation and wiring MUST be in compliance with ALL local electrical and building codes.
l
NEVER use an extension cord, 2-wire adapter, or change plug in ANY way to make it fit outlet. Be sure the
l
operator is grounded.
To avoid installation difficulties, do not activate the door operator at this time.
To reduce the risk of electric shock, your door operator 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:
OPTION A - TYPICAL WIRING
1. Plug in the door operator into a grounded outlet.
2. DO NOT run door operator at this time.
TYPICAL WIRING
OPTION B - PERMANENT WIRING
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):
1. Remove the motor unit cover screws and set the cover aside.
2. Remove the attached 3-prong cord.
3. Connect the black (line) wire to the screw on the brass terminal; the white (neutral) wire to the screw on
the silver terminal; and the ground wire to the green ground screw. The operator must be grounded.
4. Reinstall the cover.
