Siemens AG Healthcare Sector 11/12 Guidance and manufacturer’s declaration EMC
Guidance and manufacturer’s declaration — electromagnetic
emissions
The MR system is intended for use in the electromagnetic environment specified below.
The customer or the user of the MR system should assure that it is used in such an environ-
ment.
Emissions test Compliance Electromagnetic environment — guidance
Radiated RF emissions
CISPR 11
Class A/Group 2 The MR system must emit electromagnetic energy
in order to perform its intended function.
Nearby electronic equipment may be affected.
Conducted RF emissions
CISPR 11
Class A/Group 2 The MR system must be used only in a shielded
location with a minimum RF shielding effective-
ness and, for each cable that exits the shielded
location, a minimum RF filter attenuation of 80 dB
from 10 MHz to 20 MHz, 100 dB from 20 MHz to
80 MHz and 80 dB from 80 MHz to 100 MHz. (The
minimum at 20 MHz is 100 dB and the minimum
at 80 MHz is 80 dB.)
The MR system, when installed in such a shielded
location, is suitable for use in all establishments
other than domestic and those directly connected
to the public low-voltage power supply network
that supplies buildings used for domestic pur-
poses.
Harmonic emissions
IEC 61000-3-2
Not applicable
Voltage fluctuations/
flicker emissions
IEC 61000-3-3
Not applicable
Note: It is essential that the actual shielding effectiveness and filter attenuation of the shielded location
be verified to assure that they meet the minimum specification.
