SPECIFICATIONS
Guidance and manufacturer’s declaration - electromagnetic immunity
The table is intended for use in the electromagnetic environment specified below. The customer or the user of the
table should assure that it is used in such an environment.
Immunity Test
IEC 60601 test level
Compliance level
Electromagnetic
Environment - guidance
Electrostatic discharge (ESD)
IEC 61000-4-2
±6 kV contact
±8 kV air
±6 kV contact
±8 kV air
Floors should be wood, con-
crete or ceramic tile. If floors
are covered with synthetic
material, the relative humidity
should be at least 30 %.

±2 kV for power supply lines
±1 kV for input/output lines
±2 kV for power supply lines
±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 table requires
continued operation during
power mains interruptions, it
is recommended that the table
be powered from an uninter-
ruptible power supply or a
battery.
Power frequency (50/60 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 loca-
tion in a typical commercial or
hospital environment.
