Electromagnetic environment - guidance
RF emissions
CISPR 11 (partly)
Group 1
The medical used bed uses RF energy only for its internal function. Therefore, its RF emissi-
ons are very low and are not likely to cause any interference in nearby electronic equipment.
RF emissions

Class B
The
medizinisches Bett
is suitable for use in all establishments other than domestic and
those directly connected to the public-voltage power supply network that supplies buildings
used for domestic purposes.

Electrostatic discharge
(ESD)
IEC 61000-4-2
± 6 kV contact
± 8 kV air
± 6 kV contact
± 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 %.
Electrostatic transient/
burst
IEC 61000-4-4
± 2 kV for power supply lines
± 1 kV for input/output lines
± 2 kV for power supply ines
± 1 kV for input/output lines
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 medizinisches Bett requires continued
operation during power mains interruptions, it is
recommended that the medizinisches Bett be
powered from an uninterruptible power supply
or a battery.

Hz) magnetic field
IEC 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
