n Communication and Power Line
- If communication and power lines are run alongside each other then there is a strong likelihood of
operational faults developing due to interference in the signal wiring caused by electrostatic and
electromagnetic coupling. The tables below indicates our recommendation as to appropriate spacing
of communication and power lines where these are to be run side by side.
Current capacity of power line
100V or more
Notes
If the power supply waveform continues to exhibit some distortion the recommended spacing in the
table should be increased.
• If the lines are laid inside conduits then the following point must also be taken into account when
grouping various lines together for introduction into the conduits.
• Power lines (including power supply to air conditioner) and signal lines must not be laid inside the
same.
• In the same way, when grouping the lines power and signal lines should not be bunched together.
