Electromagnetic Immunity
The ventilator is intended for use in the electromagnetic environment specified below. The customer or the user of the
ventilator should ensure that it is used in such an environment.
Immunity Test
IEC / EN 60601 Test Level

IEC / EN 61000-4-2
± 6 kV contact
± 8 kV air
± 6 kV contact

Floors should be wood,
concrete, or ceramic tile. If
floors are covered with synthetic
material, the relative humidity
should be at least 30%.
Electrical fast

IEC / EN 61000-4-4
± 2 kV for power supply lines
± 1 kV for input/output lines
± 2 kV for power supply lines
± 1 kV for input/output lines
AC power (“mains”) quality
should be that of a typical
commercial or hospital
environment.
Surge

± 1 kV lines/lines
± 2 kV lines/earth
± 1 kV lines/lines
± 2 kV lines/earth
AC power (“mains”) power
quality should be that of a
typical commercial or hospital
environment.

AC power (“mains”) power
quality should be that of a
typical commercial or hospital
environment. If the user of the
ventilator requires continued
operation during power mains
interruptions, it is
recommended that the
ventilator be powered from an
uninterruptible power supply or
a battery.
Power frequency

magnetic field
IEC/ EN 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.
