Wiring Diagram For Standard Lift Doors With RJO Operators
Notes:
Junction boxes for low voltage wiring for the garage door accessories ideally will be in a plastic gang box
with a coaxial cable cover plate. Allow 2’ ft. of extra wiring at the photo eye junction boxes and 3‘ to 4’ ft. of
extra low voltage wiring near the operator low voltage wiring junction box.
Junction boxes for wall station ideally will be in a plastic gang box. LiftMaster Wall-Mounted Door Control
will screw into a gang box and act as a cover.
Multiple door gang boxes must be 2” in. apart. Junction box in ceiling by operator should be 1’ ft. off-set
and ideally should be in a plastic junction box with a coaxial cable cover.
Wires can come directly out of wall, but for best finish install junction boxes as noted above.
Operator can be mounted on left or right side of door. Power Lock and Cable Tension Monitor goes on the
same side as operator.
Dotted line wire depicted above can be stapled to wall or ran behind sheetrock and does not require conduit.
Cord length = 6’ ft. and Minimum of 12” in. is required between operator and electrical outlet.

Compliance with the NEC
It should be noted that placement of wiring should comply with the applicable provisions of the National
Electrical Code (NEC), and/or state and/or local requirements, that govern the project being undertaken.
Important NEC Information
Do not run any low voltage control wires close to the 120-volt power line. Do not run any wires through
the same holes as the 120-volt power line in studs or cross ties. Either of these conditions will not
comply with the NEC and may interfere with safe operation of the garage door operator.
