Guidance and manufacturer's declaration - electromagnetic immunity
The equipment is intended for use in the electromagnetic environment specified below. The customer or the user of the
equipment should ensure 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,
concrete or ceramic tile. If
floors are covered with
non-conductive synthetic
material, the relative hu-
midity should be at least
30%.
Electrical fast transient /
burst IEC 61000-4- 4 ±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 typi-
cal commercial or hospi-
tal environment.
Surge IEC 61000-4-5 ±1 kV differential mode
±2 kV common mode
±1 kV differential mode

Mains power quality should
be that of a typical com-
mercial or hospital envi-
ronment. If the user of the
equipment requires contin-
ued operation during power
mains interruptions, it is
recommended that the
equipment be powered
from an uninterruptible
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
location in a typical com-
mercial or hospital envi-
ronment.
