Guidance and manufacturer’s declaration – Electromagnetic immunity – Power and Signal PORTs
The AmpMC 3-field is intended for use in the Electromagnetic environment specified below. The customer or user of the
AmpMC 3-field should assure that it is used in such an environment.

a)
0,15 MHz – 80 Mhz
6 V
a)
in ISM bands between
0,15 MHz and 80 MHz
b)
80 % AM at 1 kHz
Field strengths from fixed RF transmitters, as determined by an
Electromagnetic site survey
c)
, should be less than the compliance
level in each frequency range.
Interference may occur near equipment marked with the following
symbol:
Voltage dips
IEC 61000-4-11
Not Applicable
The AmpMC 3-field is intended to be supplied by a secondary
IEC60601-1 compliant AC or DC power supply.
Voltage interruptions
IEC 61000-4-11
Not Applicable
a)
r.m.s. before modulation is applied
b)
The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553
MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz. The amateur radio bands between 0,15
MHz and 80 MHz are 1,8 MHz to 2,0 MHz, 3,5 MHz to 4,0 MHz, 5,3 MHz to 5,4 MHz, 7 MHz to 7,3 MHz, 10,1 MHz to
10,15 MHz, 14 MHz to 14,2 MHz, 18,07 MHz to 18,17 MHz, 21,0 MHz to 21,4 MHz, 24,89 MHz to 24,99 MHz, 28,0 MHz to
29,7 MHz and 50,0 MHz to 54,0 MHz.
c)
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile
radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To
assess the Electromagnetic environment due to fixed RF transmitters, an Electromagnetic site survey should be
considered. If the measured field strength in the location in which the AmpMC 3-field is used exceeds the applicable RF
compliance level above, the AmpMC 3-field should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the AmpMC 3-field.
NOTE
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people
