Transmission and Power Cables
1
Transmission cable (between outdoor and indoor units)
- Type: shielding wire
Cross section: 1.0 ~ 1.5mm
2
- Insulation material: PVC
Maximum allowable temperature: 60°C
- Maximum allowable length: under 640m
2
Remote control cable
- Type: 3-core cable
3
Central control system
4
Separation distance of transmission and power cables
- If the transmission and power cables are run alongside each other, then there is a strong
likelihood of operational failure developing due to the interference in the signal wiring caused
by electrostatic and electromagnetic coupling.
If the transmission and power cables are running alongside, keep the distance of more than
50mm between them.
- Separation distance from the power cables of other equipment

• Did you ground the both outdoor and indoor units?
• Insufficient grounding may cause electric shock. Only licensed electricians should do the
grounding work.
h
For the indoor unit grounding, the earth wire is needed to prevent the electric shock in
case of a short circuit, the communication problems due to noise, and the motor leakage
current.
WARNING
!
1
The figures are based on the assumed length of parallel cabling up to 100m. For the
length in excess of 100m the figures will have to be recalculated in direct proportion to
the additional length of cable involved.
2
If the power supply waveform continues to exhibit some distortion, the recommended
separation distance in the table should be increased.
• If the cables are laid inside the conduits or tied up to one bundle, then the following
considerations must be given to the issue.
- Do not lay the power cable and the transmission cable in the same conduit.
- Do not bind the transmission cable and the power cable together.
