Connecting Cables

Types of the cables
Classification
Power cable(CV)
Communication cable(VCTF-SB)
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.

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.
