Electromagnetism Requirements for the Equipment Room

All interference sources, inside or outside the equipment room, can cause equipment problems with capacitive coupling, inductive coupling, electromagnetic wave radiation, and common impedance (including grounding system) coupling. Prevent the interference using these approaches:

• Take effective measures against electrical interference from the power supply system.
• Do not use the working ground of the equipment as the same ground for surge protection. Separate them as far as possible.
• Keep the equipment far away from high-power radio transmitters, radar units, and high-frequency and high-current equipment.
• Use electromagnetic shielding if necessary.
