Connecting Cables

Types of the cables

The distance between communication cable and power cable

- If the power cable and communication cable are too close together, system malfunction may occur

with electrostatic, electromagnetic combination effect causing the interference signal. If communi-

cation cable is connected along with power cable, secure at least 50mm(Minimum 2 inches) dis-

tance between indoor unit power cable and communication cable.

- Cut the cable 1.5m longer than the pipe length.

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.

Classification types Cable cross section

Power cable(CV) mm

x cores 4.0 x 3

Communication cable(VCTF-SB) mm

x cores 1.0~1.5 x 2

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.

Oversize cable as necessary to maintain the power supply at the unit within ±10% of nameplate

voltage

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 conduit.

- Power cables and communication cable shall not be too close together.
