Transmission and Power Lines
1) Transmission cable
• Types : shielding wire
• Cross section : 1.0~1.5mm
2
• Maximum allowable temperature:  60°C
• Maximum allowable line length: under 1000m
2) Remote control cable
• Types : 3-core cable
3) Central control cable
4) Separation of transmission and power lines
• If transmission 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 cou-
pling.
The tables below indicates our recommendation as to appropriate spacing of transmission and power lines
where these are to be run side by side
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  
• In the same way, when grouping the lines power and signal lines should not be bunched together.

CAUTION
n 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.
