9.3 Transmission and Power Lines
1.
Transmission cable
• Types : shielding wire CVVS or CPEVS
• Use wires of size : 1.0 ~ 1.5 mm
2
• Insulation material : PVC
• Maximum allowable temperature: 60°C
• Maximum allowable line length: under 300m
2.
Remote control cable
• Types : 3-core cable
3.
Simple central control cable
• Types : 4-core cable (Shielding wire)
• Use wires of size : 1.0 ~ 1.5 mm
2
• Insulation material : PVC
4.
Separation of transmission and power lines
• If transmission and power lines are run alongside each other then here is a strong likelihood of operational
faults developing due to interference in the signal wiring caused by electrostatic and electromagnetic
coupling.
Note
1. The figures are based on assumed length of parallel cabling up to 100m. For length in excess of 100m the figures
will have to be recalculated in direct proportion to the additional length of line involved.
2. 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
conduit.
• In the same way, when grouping the power lines and signal lines should not be bunched together.
CAUTION
• 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.
• Use a power wire pipe for the power wiring.
