Electromagnetic Compatibility ( EMC, IEC 60601-1-2:2007, Table 4 )
Electromagnetic Immunity
The Invia Liberty Pump is intended for use in the electromagnetic environment
specified below. The customer or the user of the Invia Liberty Pump should assure that it is
used in such environment.
Immunity IEC 60601
Tests 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 RF 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 pre-
dicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmit-
ters, an electromagnetic site survey should be considered. If the measured field strength in the location in
which the Invia Liberty Pump isused exceeds the applicable RF compliance level above, the Invia Liberty
Pumpshould be observed to verify normal operation. If abnormal operation is observed, additional meas-
ures may be necessary, such as reorienting or relocating the Invia Liberty Pump.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V / m.

Compliance Electromagnetic
level environment-guidance
Portable and mobile RF communications equipment
should be used no closer to any part of the Invia
Liberty Pump including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance
d = 0.35
10 Vrms
d = 0.35
d = 0.7
Where P is the maximum output power rating of the
10 V/m
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 deter-
mined by an electromagnetic site survey
should be less than the compliance level in each
frequency range.
