Electromagnetic Immunity
The device is intended for use in the electromagnetic environment specified below.
WARNINGS
The user must ensure that it is used in that specific environment.
Failure to observe may generate risk situations.
Immunity Test

The second table (rif.202 of the standard cited above) concerns the various tests of immunity to interference, highlighting the type
and levels of the test, in addition to reporting important observations and recommendations for the user. The immunity is the
ability of a device to not be disturbed by electromagnetic disturbances in the environment of use, whether they are transmitted by
cable (ducts) than in air (radiated).
