Instructions for Use Fabius MRI SW 3.n 201
Technical Data
Electromagnetic immunity
The Fabius MRI is intended for use in the electro-
magnetic environment specified below. The user of
the Fabius MRI should assure that is used in such
an environment.
Immunity against IEC 60601-1-2 test level Compliance
level (of this
equipment)
Electromagnetic environment
electrostatic dis-
charge, ESD
(IEC 61000-4-2)
contact discharge: ±6 kV ±6 kV Floors should be wood, concrete or
ceramic tile. If floors are covered with
synthetic material, the relative humid-
ity shall be at least 30 %.
air discharge: ±8 kV ±8 kV
electrical fast tran-
sients / bursts
(IEC 61000-4-4)
power supply lines: ±2 kV ±2 kV Mains power quality should be that of
a typical commercial or hospital envi-
ronment.
longer input / output lines:
±1 kV
±1 kV
surges on AC

3 A/m 3 A/m In close vicinity to the Fabius MRI, no
equipment with extraordinary power
frequency magnetic fields (power
transformers, etc.) should be oper-
ated.
voltage dips and
short interruptions

lines
(IEC 61000-4-11)
dip >95 %, 0.5 periods >95 %, 0.5 per. Mains power quality should be that of
a typical commercial or hospital envi-
ronment. If user requires continued
operation during power mains inter-
ruptions, it is recommended to power
the Fabius MRI from an uninterrupt-
ible supply or a battery.
