Installation
STEP 11 Wire the door control to the garage door opener
1. Run the white and red/white wire from the door control to the garage door opener. Attach the
wire to the wall and ceiling with the staple (not applicable for gang box or pre-wired
installations). Do not pierce the wire with the staple as this may cause a short or an open
circuit.
2. Strip 7/16 inch (11 mm) of insulation from the end of the wire near the garage door opener.
3. Connect the wire to the red and white terminals on the garage door opener. If your garage is
pre-wired make sure you use the same wires that are connected to the door control. To insert
or release wires from the terminal, push in the tab with screwdriver tip.
