Mains power quality should
be that of a typical
commercial or hospital
environment. If the user of
the equipment requires
continued operation during
power mains interruptions, it
is recommended that the
equipment be powered from
an uninterruptible power
supply (UPS).
Power frequency
(50/60 HZ)
magnetic field
IEC 61000-4-8 3 A/m 3 A/m Power frequency magnetic
fields should be at levels
characteristic of a typical
location in a typical
commercial or hospital
environment.
Note: U
T
is the AC mains voltage prior to application of the test level.
Guidance and Declaration - Electromagnetic Immunity
