Guidance and manufacturer’s declaration-electromagnetic immunity
The bed is intended for use in the electromagnetic environment specified below.
The customer or the user of the bed should assure that it is used in such an environment.
Immunity test

(ESD)
IEC 61000-4-2:2009
± 8 kV contact
± 2, 4, 8, 15 kV air

± 8 kV air
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

Mains power quality
should be that of a
typical commercial or
hospital environment.

Mains power quality
should be that of a
typical commercial or
hospital environment. If
the user of the bed
requires continued
operation during power
mains interruptions, it is
recommended that the
bed be powered from an
uninterruptible power
supply or a battery.
Power frequency (50, 60

3 A/m
The bed power
frequency magnetic
fields should be at levels
characteristic of a typical
location in a typical
commercial or hospital
environment.
NOTE UT is the a.c. mains voltage prior to application of the test level.
