13.2 Interference immunity
The UNIT is intended for operation in the electromag-
netic environment specified below.
The customer or user of the UNIT should make sure that
it is used in such an environment.
Interference
immunity tests
IEC 60601-1-2 test level Compliance level Electromagnetic environment
guidelines
Electrostatic dis-
charge (ESD)
according to
IEC 61000-4-2
± 6 kV contact discharge
± 8 kV air discharge
± 6 kV contact discharge
± 8 kV air discharge
Floors should be wood, concrete, or
ceramic tile. If floors are covered with
synthetic material, the relative humid-
ity should be at least 30 %.
Electrical fast tran-
sient/burst
according to
IEC 61000-4-4
± 1 kV for input and output
lines
± 2 kV for power cables
± 1 kV for input and output
lines
± 2 kV for power cables
The quality of the line power supply
should be that of a typical commercial
or hospital environment.
Surge voltages
according to
IEC 61000-4-5
± 1 kV differential mode
± 2 kV common mode
± 1 kV differential mode
± 2 kV common mode
The quality of the line power supply
should be that of a typical commercial
or hospital environment.
Voltage dips, short
interruptions and vari-
ations of the power
supply
according to
IEC 61000-4-11
< 5 % U
T
for ½ period
(> 95 % dip of U
T
)
40 % U
T
for 5 periods
(60 % dip of U
T
)
70% U
T
for 25 periods
(30 % dip of U
T
)
< 5 % U
T
for 5 sec.
(> 95 % dip of U
T
)
< 5 % U
T
for ½ period
(> 95 % dip of U
T
)
40 % U
T
for 5 periods
(60 % dip of U
T
)
70 % U
T
for 25 periods
(30 % dip of U
T
)
<5 % U
T
for 5 sec.
(> 95 % dip of U
T
)
The quality of the line power supply
should be that of a typical commercial
or hospital environment.
If the user of the UNIT requires it to
continue functioning following inter-
ruptions of the power supply, it is rec-
ommended to have the UNIT
powered by an uninterruptible power
supply or a battery.
Magnetic field of
power frequencies
(50/60 Hz)
according to
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 commer-
cial or hospital environment.
Remarks: U
T
is the AC supply voltage prior to application of the test level.
