2.2.6 EMI Requirements
All interference sources, either from outside or inside of the device or application system, affect the device by capacitive
coupling, inductive coupling, or electromagnetic waves.
Electromagnetic interference (EMI) occurs due to electromagnetic radiation or conduction, depending on the transmission
path.
When the energy, often RF energy, from a component arrives at a sensitive component via the space, the energy is
known as radiated interference. The interference source can be both a part of the interfered system and a completely
electrically isolated unit. Conducted interference results from the electromagnetic wire or signal cable connection between
the source and the sensitive component. The interference is conducted from one unit to another unit through cables.
Conducted interference often affects the power supply of the equipment, but can be controlled by a filter. Radiated
interference may affect any signal path in the equipment, and is difficult to shield.
Take interference prevention measures for the power supply system.
Keep the switch far away from the lightening protection and grounding system of the power device.
Keep the switch far away from high-frequency current devices such as high-power radio transmitting station and
radar launcher.
Take electromagnetic shielding measures when necessary.
