•
From the ground terminal, run a heavy wire directly to the ground rod. If necessary, run a
heavy ground wire to the electrical service grounding system rather than directly to the ground
rod.
•
Do not use light wires for these ground connections. They must carry heavy lightning currents,
sometimes exceeding thousands of amperes. Certainly, do not use the shielding of sensor
and low voltage wiring for this purpose.
•
When splicing sensors to longer wires, ensure that the splice is waterproof. Use adhesive
lined heat shrink (marine grade) to make waterproof connections.
•
Every low power device (digital, analog, or communication) must have a shield cable
connected to the unit ground strip.

ONNECTIONS
•
Install computerized electronic controls at least three feet (one meter) away from interference
sources such as high voltage wiring to motors, variable speed, light dimmers, relays.
•
Install electronic controls in a separate ventilated control room that is protected from extreme
temperatures and dirty environments. Place the controls so that the operators can
conveniently use the control and read indicators and displays.
•
Keep low voltage wires separate from high voltage wires.
•
Use shielded wiring for low level signals. For buried wiring (building to building runs) use
high grade jell filled cables that are impervious to moisture.
•
Seal cable entry points and control boxes to prevent contamination and corrosion. If you use
silicon sealant with acetic acid cure, keep the control open and ventilated until cured.
Otherwise, the acetic acid will attack the metal parts, including circuitry.
•
Drill cable entry holes on the bottom of the box only.
