Power - Chamberlain POWER DRIVE PD300 Manual

Installation
STEP 15 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.
THERE ARE TWO OPTIONS FOR CONNECTING POWER:
OPTION A
TYPICAL WIRING
1. Plug in the garage door opener into a grounded outlet.
2. DO NOT run garage door opener at this time.
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 opener
must be grounded.
4. Reinstall the cover.
