EID for Non-Life-Support Functions
The non-life-support functions
a
of the E Series unit are intended for use in the electromagnetic environment specified
below. Ensure that the unit is used in such an environment.
Immunity Test IEC 60601 Test Level Compliance Level Electromagnetic Environment — Guidance
Portable and mobile RF communications equip-
ment should be used no closer to any part of the
E Series unit, including cables, than the recom-
mended separation distance calculated from the
equation applicable to the frequency of the trans-
mitter.
Recommended Separation Distance
Conducted RF
IEC 61000-4-6
3Vrms
150 kHz to 80 MHz
3Vrms
d = 1.2
Radiated RF
IEC 61000-4-3
3V/m
80 MHz to 2.5 GHz
10 V/m
d = 0.35 80 MHz to 800 MHz
d = 0.7 800 MHz 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 recom-
mended separation distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
b
should be less than the compliance level in each
frequency range.
c
Interference may occur in the vicinity
of equipment marked with the follow-
ing symbol:
NOTE 1 At 80 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
The non-life-support functions on the E Series unit are defined to be any function not listed as a life-support function
in the “EID for Life Support Functions” table (Note a).
b
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 E Series unit is used exceeds the
applicable RF compliance level above, the E Series unit should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the E Series unit.
c
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
