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 DS-60 cables away from the transmission antenna cable or radio equip- ment.

•Locate the DS-60 cables away from the power cables mentioned below. Also, sep- arate cables at least 400 mm when the cables are run parallel with power cables.

•Cable carrying more than a few kilowatts power to fluctuating loads

•Cable carrying switching waves generated by thyristor, etc.
