WIRING INSTRUCTIONS
Disconnect power at the fuse box 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 connected 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 circuit of adequate capacity is needed for the operator.
7. The operator must be properly grounded. The ground screw, painted green, is located inside the
