Immunity test IEC 60601 test level Compliance level Electromagnetic environment - guidance
Conducted RF
IEC 61000-4-6
3 Vrms
150 kHz to 80 MHz
3 Vrms Portable and mobile RF communications equipment should be used no
closer to any part of the Compat Ella
®
pump, including cables, than the re-
commended 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 meters (m).
Field strengths from fixed RF transmitters, as determined by an electro-
magnetic 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:
Radiated RF
IEC 61000-4-3
3 V/m
80 MHz to 2.5 GHz
3 V/m
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 envi-
ronment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location
in which the Compat Ella
®
pump is used exceeds the applicable RF compliance level above, the Compat Ella
®
pump should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or reloca-
ting the Compat Ella
®
pump.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
