Guidance and manufacturer's declaration – electromagnetic immunity
The Model Smart Control is intended for use in the electromagnetic
environment specified below. The customer or the user of the Model Smart
Control should assure that it is used in such an environment.
Immunity IEC 60601
test 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 Model Smart Control is used exceeds the applicable RF compliance level above, the Model
Smart Control should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the Model Smart Control.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Compliance
level
Portable and mobile RF communications
equipment should be used no closer to any
part of Smart Control, including cables, than
the recommended separation distance
calculated from the equation applicable
to the frequency of the transmitter.

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 electromagnetic site survey,
should be less than the compliance level in each
frequency range
Interference may occur in the vicinity of equip-
