Lightening Protection
Extremely high voltage currents can be produced instantly when lightning occurs and the air
in the electric discharge path can be instantly heated up to 20,000℃. As this instant current
is strong enough to damage electronic devices, more effective lightning protection measures
should be taken.
Ensure the rack and device are well earthed.
■
Make sure the power socket has a good contact with the ground.
■
Keep a reasonable cabling system and avoid induced lightning.
■
Use the signal SPD (Surge Protective Device1 when wiring outdoor.
■
Note: For detailed lightning protection measures, please refer to Chapter 3
Lightning Protection.
