Power - Chamberlain HD210C Manuel

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
l
removing cover to establish permanent wiring connection.
Garage door installation and wiring MUST be in compliance with ALL local electrical and building
l
codes.
NEVER use an extension cord, 2-wire adapter, or change plug in ANY way to make it fit outlet. Be
l
sure the opener is grounded.
To avoid installation difficulties, do not run the 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 the outlet you
have, 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.
