Mains power quality should be that of a typical
commercial or hospital environment. If the user of the
device requires continued operation during mains
interruptions, it is recommended that the device be
powered from an uninterruptible power supply.
<5% U
T
(>95% dip in U
T
)
for 5 seconds
If the user of the device requires continued operation
during mains interruptions, it is recommended that the
device be powered from an uninterruptible power supply.
Power frequency
(50/60Hz)
Magnetic field
IEC61000-4-8
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 a.c. mains voltage prior to the application of the test level.
Conductive RF
IEC61000-4-6
3Vrms
150kHz to 80MHz
Portable and mobile RF communications equipment
should be used no closer to any part of the device,
including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance
d=1.2√P
Radiated RF
IEC61000-4-3
3V/m
80MHz to 2.5GHz
d=1.2√P 80MHz to 800MHz
d=2.3√P 800MHz to 2.5GHz
Where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation
distance in metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic survey,
a
should be
less than the compliance level in each frequency range.
b
Interference may occur in the vicinity of equipment
marked with:
Note 1: At 80MHz and 800MHz the higher frequency range applies.
Note 2: These guidelines may NOT apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
