EMI

All electromagnetic interference (EMI) sources, from either outside or inside of the device and application
system, adversely affect the device in a conduction pattern of capacitance coupling, inductance coupling,
electromagnetic wave radiation, or common impedance (including grounding system) coupling. To
prevent EMI, follow these guidelines:
• Use a socket with three pins and PE wire to prevent interference from the power grid.
Use a grounding system and a lightning protection system for the device separate from those for
•
other electric equipment, and keep them far away as possible.
Keep the device far away from high-power radio launchers, radars, and equipment with high
•
frequency or high current.
• Use electromagnetic shielding, for example, shielded interface cables, when necessary.

Lightning protection

To better protect the device from lightning, follow these guidelines:
• Make sure the grounding cable of the chassis is well grounded.
Make sure the grounding terminal of the AC power receptacle is well grounded.
