Guidance and manufacturer's declaration - electromagnetic immunity
The pump is intended for use in the electromagnetic environment specified below. The customer or the user of
the pump should assure that it is used in such an environment.
Immunity IEC 60601 Test
Test
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 2.5GHz
Note: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note: 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 pump is used exceeds
the applicable RF compliance level above, the pump should be observed to verify normal operation. If abnormal
operation is observed, additional measures may be necessary, such as reorientating or relocating the pump.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Electromagnetic environment - guidance
Portable and mobile RF communications
equipment should be used no closer to any part of
the pump, including cables, that the
recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.
Recommended separation distance
d = 1.2√P
d = 1.2√P 80 MHz to 800 MHz
d = 2.3√P 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
recommended separation distance in metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey
should be less than the compliance level in each
b
frequency range.
Interference may occur in the vicinity of
equipment marked with the following symbol:
