Electromagnetic compatibility
Electromagnetic Compatibility (EMC) is the ability of an electrical device to operate as
intended in an electromagnetic environment and to operate without emitting levels of
electromagnetic interference (EMI) that may disturb other electrical devices in the vicinity.

Surge immunity
Wiring systems subject to surges from lightning strike coupling must be equipped with
external protection. One specification for evaluation of protection from lightning type surges
is found in EN 61000-4-5, with operational limits established by EN 61000-6-2. S7-1200 DC
CPUs and signal modules require external protection to maintain safe operation when
subject to surge voltages defined by this standard.
Listed below are some devices that support the needed surge immunity protection. These
devices only provide the protection if they are properly installed according to the
manufacturer's recommendations. Devices manufactured by other vendors with the same or
better specifications can also be used:
