Guidance and manufacturer's declaration - electromagnetic immunity
The LM-ProPower is intended for use in the electromagnetic environment specified below.
The customer or the user of the LM-ProPower should assure that it is used in such an environment.
Immunity test
IEC 60601 test level
Conducted RF
3 Vrms
IEC 61000-4-6
150 kHz to 80 MHz
Radiated RF
3 V/m
IEC 61000-4-3
80 MHz to 2,5 GHz
NOTE 1
At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2
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 fro 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 LM-ProPower is used exceeds the applicable RF compliance level
above, the LM-ProPower should be observed to verify normal operation. If abnormal performance is observed additional
measures may be necessary, such as reorienting or relocating the LM-ProPower.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Compliance
Electromagnetic environment - guidance
level
Portable and mobile RF communications equipment
should be used no closer to any part of the
LM-ProPower 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 V
d = 1,2√P
3 V/m
d = 2,3√P
were 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).
Field strengths from fixed RF transmitters as deter-
mined by an electromagnetic site survey,
than the compliance level in each frequency range.
