Guidelines and manufacturer's declaration – electromagnetic immunity
The model ASG 341 is intended for operation in an electromagnetic environment as specified
below. The customer or the user of the model ASG 341 should ensure that it is used in such
an environment.
Immunity tests
IEC 60601 –
test level
Conformity
level
Electromagnetic environment –
guidelines
Electrostatic
discharge immunity
test according to
IEC 61000-4-2
± 6 kV contact
discharge
± 8 kV air
discharge
Not applicable
± 8 kV air
discharge
Floors should be made of wood or
concrete or furnished with ceramic
tiles. If the floor is furnished with
synthetic material, the relative air
humidity must be at least 30%.
Electrical fast
transient/burst
immunity according
to IEC 61000-4-4
± 2 kV for power
cables
± 1 kV for input
and output cables
Not applicable
The quality of the supply voltage
should correspond to the voltage
of a typical commercial or hospital
environment.
Surges according to
IEC 61000-4-5
± 1 kV differen-
tial mode voltage
± 2 kV common
mode voltage
Not applicable
The quality of the supply voltage
should correspond to the voltage
of a typical commercial or hospital
environment.
Voltage dips, short
interruptions and
voltage variations
according to IEC
61000-4-11
< 5% UT (>95 %
dip of UT) during
½ period 40% U
T
(60% dip of UT)
during 5 periods
70% UT (30% dip
of UT) during 25
periods < 5% UT
(> 95% dip of UT)
during 5 s
Not applicable
The quality of the supply voltage
should correspond to the voltage
of a typical commercial or hospital
environment. If the user of the
model ASG 341 requires a
continuous function also when
interruptions in the energy supply
occur, it is recommended to supply
the model ASG 341 from an
uninterruptible power source or a
battery.
Magnetic fields at
the power frequency
(50/60 Hz)
according to IEC
61000-4-8
3 A/m
3 A/m
Magnetic fields at the power
frequency should correspond to
typical values that can be found in
a commercial or hospital
environment.
NOTE U is the alternating mains voltage prior to application of test levels.
