4. AC 110V/AC 220V/DC 24V cables must be properly twisted and connected with the shortest
distance.
5. AC 110V/AC 220V cable must be as thick as possible (2mm
110V/ DC 24V cables must not be installed close to the main circuit cable (high voltage/high
current) and I/O signal cable. They must be 100mm away from such cables. 
6. Use a surge absorber as a protection against lightning, as displayed in the following figure.
TIP
Separate PLC earth (E2) from earth (E1) of surge absorber against lightning.

In case of an increase in voltage, the surge absorber ensures that it does not increase more
l
than the predefined maximum limit. 
Use a shielded isolation transformer or noise filter in areas where higher noise levels are
l
expected.
It is advisable to use twisted cable for input power. Ensure that the shielded transformer or
l
noise filter wiring does not pass the duct.
