Indoor power source and communication wiring
Power cable and communication wire must be xed rmly.
Each indoor must be grounded well.
When power cable exceeds the range, increase the gauge appropriately.
Shielded layer of communication wires must be connected together and be earthed at single point.
The total length of communication wire cannot exceed 1000m.
Shielded layer of communication wire must be grounded at one end.
The total length cannot exceed 600m.
