Electrical Requirements

INSTALLATION STEP 8

To avoid installation difficulties, do not run the opener until Step 11 below.

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.

If permanent wiring is required by your local code, refer to the following procedure.

To make a permanent connection through the 7/8" hole in the top of the motor unit:

•Remove the motor unit cover screws and set the cover aside.

•Remove the attached 3-prong cord.

•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.

•Reinstall the cover.

To avoid installation difficulties, do not run the opener at this time.

To prevent possible SERIOUSINJURYor DEATHfrom electrocution or fire:

•Besure power is not connected to the opener,and disconnect power to circuit BEFOREremoving cover to establish permanentwiring connection.

•Garagedoor installation and wiring MUSTbe in compliance with ALL local electrical and building codes.

•NEVERuse an extension cord, 2-wire adapter,or change plug in ANY wayto make it fit outlet. Besure the opener is grounded.

ALIGNING THE SAFETY REVERSING SENSORS

•Plug in the opener. The indicator lights in both the sending and receiving eyes will glow steadily if wiring connections and alignment are correct.

The sending eye amber indicator light will glow regardless of alignment or obstruction. If the green indicator light in the receiving eye is off, dim, or flickering (and the invisible light beam path is not obstructed), alignment is required:

•Loosen the sending eye wing nut and readjust, aiming directly at the receiving eye. Lock in place.

•Loosen the receiving eye wing nut and adjust the sensor until it receives the sender's beam. When the

green indicator light glows steadily, tighten the wing nut.

TROUBLESHOOTING THE SAFETY

REVERSING SENSORS

1.If the sending eye indicator light does not glow steadily after installation, check for:

•Electric power to the opener.

•A short in the white or white/black wires. These can occur at staples, or at opener connections.

•Incorrect wiring between sensors and opener.

•A broken wire.

2.If the sending eye indicator light glows steadily but the receiving eye indicator light doesn't:

•Check alignment.

•Check for an open wire to the receiving eye.

3.If the receiving eye indicator light is dim, realign either

sensor.

NOTE: When the invisible beam path is obstructed or misaligned while the door is closing, the door will reverse. If the door is already open, it will not close. The opener lights will flash 10 times. (See page 15.)
