Anti-Interference
The AP is susceptible to external interference by capacitive coupling, inductive coupling, electromagnetic waves, common
impedance (ground) coupling, or conduction over power lines, signal lines and output lines. Note that:
In a TN earthing system, use a 3-wire single-phase outlet that has a protective earth (PE) contact to allow the filter
circuit in the device to eliminate interference from the power grid.
Keep the AP away from high-power radio stations, radar stations, and high-frequency high-current devices.
Use EMI shielding such as shielded interface cables to minimize interference when necessary.
Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or overcurrent
caused by lightning strikes.
