EMI
Electromagnetic interference (EMI) might be coupled from the source to the router through the following
coupling mechanisms:
• Capacitive coupling
• Inductive coupling
• Radiative coupling
• Common impedance coupling
• Conductive coupling
To prevent EMI, take the following actions:
• Take measures against interference from the power grid.
• Do not use the router together with the grounding equipment or light-prevention equipment of
power equipment, and keep the router far away from them.
• Keep the router far away from high-power radio launchers, radars, and equipment with high
frequency or high current.
NOTE:
Use electromagnetic shielding when necessary.
