Outdoor unit communication cable connection
• If the power cable and the communication cable are connected in parallel, it can cause
malfunction to the system by signal interference from combined effect from static electric and
electronic system. When the communication cable is installed with the indoor unit power cable,
clearance of at least 50mm must be secured between the two.
• Clearance with power cable from other system
Power cable current capacity
100V or above
1. This is calculated based on the assumption of cable length of 100m running parallel. If the
cable runs over 100m, additional length must be calculated in proportion.
2. If the waveform of the power is continuously distorted even after maintaining the above
clearance distance, try extending the clearance distance.
I If several cables are put in the transmission cable or tied as one, the following must be
considered.
- The power cable and the communication cable cannot be put together in the transmission
cable.
- The power cable and the communication cable cannot be tied together.
