Precautions for cable installation
Observe the following guidelines to prevent noise, interference problem.
•The transducer cable carries very weak signals (amplitude less than 0.1 μV), which are easily interfered by noise. The need for a good ground cannot be overempha- sized.
•Locate
•Locate the
•Cable carrying more than a few kilowatts power to fluctuating loads
•Cable carrying switching waves generated by thyristor, etc.
