fabian +nCPAP evolution | SW V5.1.x
Ref: 122003.EN / Date : 26Jan2021
Guideline and manufacturer declaration – electromagnetic immunity
<5% UT
(>95% drop of UT) for
5 seconds
<5% UT
(>95% drop of UT) for
5 seconds
Magnetic field at
supply frequency
(50/60 Hz)
IEC 61000-4-8
Magnetic fields at the mains frequency
should correspond to typical values in
business and hospital environments.
Remark UT is the mains alternating voltage prior to applying the test level.
Guideline and manufacturer declaration – electromagnetic immunity
The device "fabian +nCPAP evolution" is intended for operation in the environment described below. The
customer or user of the " fabian +nCPAP evolution " apparatus should ensure it is operated in this type of
environment.
Electromagnetic environment – guideline
Never use portable or mobile radio devices closer to
the "fabian +nCPAP evolution", including cables,
than the recommended safety distance calculated
using the equation applicable to the transmission
frequency.
Recommended safety distance
HF
interference
currents
IEC 61000-4-6
3 Veff
150 kHz to 80 MHz
beyond ISM bands a
10 Veff
150 kHz to 80 MHz
within ISM bands b
HF
interference
radiation
IEC 61000-4-3
d = 1.2√P 80 MHz to 800 MHz
d = 2.3√P 800 MHz to 2.5 GHz
P being the transmitter’s nominal rating in Watts
(W) per manufacturer specifications and d being the
recommended safety distance b in metres (m).
The field strength of stationary radio transmitters
should be below the compliance level d on all
frequencies as tested on site c.
Interference may occur in proximity of apparatuses
bearing the following symbol:
REMARK 1 At 80 MHz and 800 MHz the higher frequency range applies.
REMARK 2 These guidelines may not apply to all case. The propagation of electromagnetic quantities is
influenced by absorption and reflexion of buildings, objects and people.
