Interference immunity
The UNIT is intended for operation in the electromagnetic environment
specified below.
The customer or user of the UNIT should make sure that it is used in
such an environment.

Electrostatic dis-
charge (ESD) ac-
cording to IEC
61000-4-2
± 8 kV contact
± 15 kV air
± 8 kV contact
± 15 kV air
Floors should be wood, concrete, or
ceramic tile. If the floor is covered
with synthetic material, the relative
humidity must be at least 30%.
Electrical fast tran-
sient/burst accord-
ing to
IEC 61000-4-4
± 1 kV for input and out-
put lines
± 2 kV for power supply
lines
± 1 kV for input and
output lines
± 2 kV for power supply

The quality of the line power supply
should be that of a typical commer-
cial or hospital environment.

The quality of the line power supply
should be that of a typical commer-
cial or hospital environment.
Continued operation of the UNIT is
possible following interruptions of
the power supply, since the UNIT is
powered by an uninterruptible power
supply backed up by a storage bat-
tery.
Magnetic field of

ing to
IEC 61000-4-8

30 A/m
Power frequency magnetic fields
should be at levels characteristic of
a typical location in a typical com-
mercial or hospital environment.
Note: U
T
is the AC supply voltage prior to application of the test level.
Portable and mobile radio equip-
ment must not be used within the
recommended working clearance
from the UNIT and its cables, which
is calculated based on the equation
suitable for the relevant transmission
frequency.
Recommended working clearance:
