Power - Chamberlain PD220 Manual De Instrucciones

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 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. DO NOT change the plug in any way.
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. Be sure power is NOT connected to the opener, and disconnect power to the circuit.
2. Remove the motor unit cover screws and set the cover aside.
3. Cut the power cord 6 inches (15.2 cm) from the top of the garage door opener.
4. Remove the strain relief.
5. Pull the power cord wires back into the garage door opener.
6. Install conduit or flex cable adapter in the 7/8 inch hole.
7. Run the permanent wires through the conduit in the 7/8 inch hole. Strip the insulation from the
ends of all wires.
8. Connect the black (line) wire to the existing black wire; the white (neutral) wire to the existing
white wire; and the ground wire to the existing green ground wire with wire nuts. The opener
must be grounded.
9. Properly secure the wires with plastic ties so that the wires do not come in contact with moving
parts.
