12-8 Fresenius Medical Care multiFiltrate IFU-EN-UK 15A-2015
Voltage dips, short
interruptions, and
voltage variations
according to
IEC 61000-4-11 < 5% U

(> 95% dip
of the
U
T
) for
0.5 periods
< 5% U
T
(> 95% dip
of the
U
T
) for
0.5 periods
The quality of the supply voltage should
correspond to that of a typical commercial
and / or hospital environment. If the
operator of the multiFiltrate device requires
continuous operation, even in the event of
interruptions in the energy supply, it is
advisable to supply the multiFiltrate using
an uninterruptible power supply or a
battery.

Power frequency
magnetic fields
(50 / 60 Hz)
according to
IEC 61000-4-8 3 A/m 3 A/m Power frequency magnetic fields should
correspond to the typical values found in
the commercial and hospital environment.
Note: U
T
is the AC voltage before the test level is applied.
Portable and mobile radio devices should
not be any closer to the multiFiltrate device
(including the lines) than the
recommended safety distance, which is
calculated according to the relevant
equation for the transmission frequency.
Recommended safety distance:

Where P is the nominal power of the
transmitter in watts (W) in accordance with
the information from the transmitter
manufacturer and d is the recommended
safety distance in meters (m).
In accordance with an investigation on
site

transmitters should be lower than the
compliance level for all frequencies
