WIRING INSTRUCTIONS
Disconnect power at the fuse box and the operator before proceeding with
any wiring.
1. Do not install any wiring or attempt to run this operator without checking the wiring diagram
located on the inside of the control box cover.
2. Do not turn on power until you have finished making all power and control wiring connections.
3. Do not run power and control wiring in the same conduit.
4. Any wire connecting to the control panel must be protected by conduit or other means to ensure
the safety and permanency of the wiring.
5. Use copper wire inside the control panel.
6. A separate fuse line of adequate capacity is needed for the operator.
7. The operator must be properly grounded. The ground screw, plated green, is located inside the
control panel.
Failure to properly ground the operator could result in electric shock and
serious injury or death.
To avoid damage to door and operator, make all door locks inoperative.
Secure lock(s) in the unlocked position, or install electrical interlocks to
prevent operation with the lock engaged.
