Connecting Cables
Types of the cables
The distance between communication cable and power cable
- If the power cable and communication cable are tied together, system malfunction may occur with
electrostatic, electromagnetic combination effect causing the interference signal. If communication
cable is connected along with power cable, secure at least 50mm distance between indoor unit
power cable and communication cable.
It is the value with the assumption of the length of the parallel cable as 100 m. If it is longthan 00m,
it shall be calculated again with proportional to the added length.
If the distance is secured as the previous page, and the distortion in the waveform of the power still
occurs, increase the distance.
※ When several power cables are inserted into the transmission line, or tied together, make sure to
consider the following issues.
- Power cables and communication lines shall not be in the same transmission line.
- Power cables and communication lines shall not be tied together.

WARNING
• Are all of the indoor units and outdoor units grounded?
• If grounding is not properly done, there is a risk of electric shock. Grounding must be done by a
qualified technician.
• Consider the surrounding conditions(surrounding temperature, direct sunlight, rain water, etc.)
when wiring the cable.
• The thickness of the power cable is the minimum thickness of metal conductor cable. Use
thicker cable considering the voltage drop.
It is the value with the assumption of the length of the parallel cable as 100 m.
If it is longer than 100m, it shall be calculated again with proportional to the added length.
If the distortion in the waveform of the power still occurs despite securing the distance, increase
the distance.
※ When several power cables are inserted into the transmission line, or tied together, make sure
to consider the following issues.
- Power cables and communication cable shall not be in the same transmission line.
- Power cables and communication cable shall not be tied together.
