Electromagnetic Interference
Electronic components including capacitance and inductance on
the device can be affected by external interferences, such as
conducted emission by capacitance coupling, inductance coupling,
and impedance coupling. To decrease the interferences, please
make sure to take the following measures:
Use the power supply that can effectively filter interference from
the power grid.
Keep the devices far from high-frequency, strong-current devices,
such as radio transmitting station.
Use electromagnetic shielding when necessary.
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:
