Guidance and Manufacturer’s Declaration – Electromagnetic Immunity
The SwiSto3 is intended for use in the electromagnetic environment specified below.
The customer or user is to assure that it is used in such an environment.

IEC 61000-4-2
± 6 kV contact discharge

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

Mains power quality should be that
of a typical commercial or hospital
environment. If the user of the device
requires continued OPERATION during
a power mains interruption, it is
recommended that the device be
powered by an uninterruptible power
supply or battery.
Power frequency
(50/60 Hz) magnetic field
IEC 61000-4-8
3 A/m
3 A/m
If interference occurs, it may be
necessary to place the SwiSto3 further
away from the sources of power
frequency magnetic fields or to install a
magnetic shield: The power frequency
magnetic field should be measured at
the designated site to ensure that it is
not large enough to cause interference.
Note:
U
T
is the ac mains voltage prior to application of the test level.
