- Maximum allowable cable length: under 300 m
Remote control cable
- Types : 3-core cable
Central control cable
Separation of communication and power cables
- If communication and power cables 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 cables where these are to be run side by side
NOTE
!
• The figures are based on assumed length of parallel cabling up to 100 m. For length in
excess of 100 m the figures will have to be recalculated in direct proportion to the
additional length of cable involved.
• If the power supply waveform continues to exhibit some distortion the recommended
spacing in the table should be increased.
- If the cable are laid inside conduits then the following point must also be taken into
account when grouping various cable together for introduction into the conduits
- Power cable(including power supply to air conditioner) and communication cables
must not be laid inside the same
- In the same way, when grouping the power wires and communication cables should not
be bunched together.

If apparatus is not properly earthed then there is always a risk of electric shocks, the earthing of
the apparatus must be carried out by a qualified person.
