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, than 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 a , should be less than the compliance
level in each frequency range.
Interference may occur in the vicinity of
equipment marked with the following symbol:
