by capacitance coupling, inductance coupling, and impedance coupling.
To decrease the interferences, make sure to take the following measures:
■
Use the power supply that can effectively filter interference from the
power grid.
■
Keep the device far from high-frequency and strong-current devices
such as radio transmitting station.
■
Use electromagnetic shielding when necessary.

VIGI NVR4032H
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
°C. As this instant current is strong enough to
damage electronic devices, more effective lightning protection measures
should be taken.
■
Ensure that the rack and the 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 Device) when wiring outdoor.
