Guidance and manufacturer’s declaration – electromagnetic immunity
The SIH21/2 is intended for use in the electromagnetic environment specified below. The customer or the
user of the SIH21/2 should assure that it is used in such an environment
Immunity test EN 60601

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 humi-
dity should be at least 30 %
Electrical fast
transient/burst
IEC 61000-4-4
±2 kV for power sup-
ply lines
±1 kV for input/output
lines
±2 kV for power supply
lines
Mains power quality should be that
of a typical commercial or hospital
environment.
The electrical fast transient burst
(EFT) is generated by the switching of
inductive loads. Separation between
the equipment and other loads shall
be considered before installation.
Mains filter is required, if necessary.
Surge
IEC 61000-4-5
±1 kV line(s) to line(s)
±2 kV line(s) to earth
±1 kV line(s) to line(s)
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 en-
vironment. If the user of the SIH21/2
requires continued operation during
power mains interruptions, it is re-
commended the SIH21/2 be powered
from an uninterruptible power supply
or a battery.

Power frequency magnetic fields
should be at levels characteristic of a
typical location in a typical commer
