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.
