OUTDOOR UNIT COMMUNICATION LINE CONNECTION
25
ENGLISH
COMM. Cautions on connecting the PCB with outdoor unit
- The system can malfunction if the power and communication lines are connected next to each
other, because of the interference signal that can be created by the combination of static and
electronic cables. When connecting the communication line along with the power line for the in-
door unit, the power and communication lines must be at least 50mm apart.
- Distance with the power cables of other equipment
Power Cable Current Capacity Distance
100 V or more
10 A 300 mm
50 A 500 mm
100 A 1 000 mm
Exceeding 100 A 1 500 mm
CAUTION
• The calculation is based on two 100 m cables running parallel to each other The distance
must be recalculated in direct proportion to the length if the length is over 100 m.
• Increase the distance if the power wave is still distorted even after keeping the distance as
described above.
- Make sure to consider the following when inserting multiple power cables into the trans-
mission cable or tying them together.
* Do not insert the power cable and communication cable into the same transmission
cable.
* Do not tie the power and communication cables together.
