The
UNIT
is intended for operation in the electromagnetic
environment specified below.
The customer or user of the
UNIT
should make sure that it
is used in such an environment.
3.3 Immunity to interference
Immunity interfer-
ence tests
IEC 60601-1-2 test level
Conformance level
Electromagnetic environment
guidelines
Electrostatic dis-
charge (ESD) accord-
ing to
IEC 61000-4-2
± 6kV contact discharge
± 8 kV air discharge
± 6kV contact discharge
± 8kV air discharge
Floors should be made of wood or
concrete or covered with ceramic til-
ing. If the floor surface consists of
synethetic material, the relative
humidity must be at least 30%.
Electrical fast tran-
sient/burst
according to
IEC
61000-4-4
± 1kV for input and output
lines
± 2kV power cables
± 1kV for input and output
lines
± 2kV power cables
The quality of the supply voltage
should conform to the typical busi-
ness or hospital environment.
Surge voltages
according to
IEC
61000-4-5
± 1kV push-pull voltage
± 2kV push-pull voltage
± 1kV push-pull voltage
± 2kV push-pull voltage
The quality of the supply voltage
should conform to the typical busi-
ness 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

for 5sec. (>95% dip
of U
T
)
<5% U
T
for ½ period
(>95% dip of U

)
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 5sec.
(>95% dip of U
T
)
The quality of the supply voltage
should correspond to the typical busi-
ness 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
The power frequency magnetic fields
should correspond to the typical val-
ues found in the relevant business
and hospital environment.
Remarks: U
T
is the AC supply voltage prior to application of the test level.
