Guidance and manufacturer's declaration-electromagnetic immunity
The MCB 300K100M, MPT 300K100M is intended for use in the electromagnetic environment
specified below.
The customer or the user of the MCB 300K100M, MPT 300K100M should assure that is used in
such and environment.
Immunity test IEC 60601 test level
3 Vrms
Conducted RF
IEC 61000-4-6 150 KHz to 80 MHz
Radiated RF IEC 3 V/m 80MHz to
61000-4-3 2,5 GHz
NOTE1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
a 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 MCB 300K100M, MPT 300K100M is used exceeds the applicable RF compliance level above, the
MCB 300K100M, MPT 300K100M should be observed to verify normal operation. If abnormal
performance is observed, additional measures my be necessary, such as re-orienting or relocating the
MCB 300K100M, MPT 300K100M
b Over the frequency range 150 kHz to 80 MHz, field strengths should be les than 3 V/m.

Compliance level Electromagnetic environment-guidance
Portable and mobile RF communications
equipment should be used no closer to
any part of the MCB 300K100M, MPT
300K100M
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter.
Recommended separation distance:
d = 1,2 √P
3 Vrms
d = 1,2 √P 80MHz to 800 MHz
d = 2,3 √P 800MHz to 2,5 GHz
Where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter manufacturer
and d is the recommended separation
distance in metres (m).
