Do not run wiring outside the building.
If you install the unit in a metal building, keep the wiring at least 2 ft (0.61 m) away from
external metal surfaces. Make a proper earth ground connection.
Earth ground the unit correctly. Do not use an electrical ground or telephone ground.
Avoid running wires near telephone, data, or power lines. Locating control panel wiring at
least 2 ft (0.61 m) away helps reduce the effects of lightning.
When your data lines must cross the path of AC or other wiring, cross perpendicular to
the lines.
