2.1.4 Electromagnetic Environment Requirements

All interference sources, wherever they are from, impact the

firewall negatively in the conducted emission patterns of capacitance

coupling, inductance coupling, electromagnetic wave radiation, and

common impedance (including the grounding system) coupling. To

resist the interference, make sure to:

z Take effective measures against the interference caused by

the electrical power grid.

z Do not use same grounding system for the ground of your

firewall device and the power equipment ground or the

lightning protection ground.

z Keep the device far from heavy-duty radio transmitters,

radar transmitters, and high-frequency devices.

z Use electromagnetic shielding when necessary.
