2.1 Precautions for Cable Installation
Cable between transducer unit and transceiver unit
This cable carries very weak signals with amplitude of less than 0.1 µV which are easily
interfered by noise. Ensure the ground wiring.
Cable between transceiver unit and distribution box
These cables carry echo signals with amplitudes of greater than 0.1 mV which can be interfered
by noise from high tension power cables.
• Cable carrying more than few kilowatts power to fluctuating loads.
• Cable carrying switching waves generated by thyristor, etc.
• Transmission antenna cable of radio equipment.
Other cables of DS-80
Observe the following guidelines to prevent noise, interference problem.
• When the cables run in parallel with power cables, separate them 400 mm at minimum.
