Section 5: Reference
Electromagnetic immunity declaration
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.
Immunty test IEC 00
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 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 performance is observed, additional mea-
sures may be necessary, such as reorienting or relocating the Pump.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 13 V/m.

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 equa-
tion applicable to the frequency of the
transmitter.
