±6 kV contact Floors should be wood, concrete
or ceramic tile. If floors are
±8 kV air
covered with synthetic material,
the relative humidity should be at
least 30%.
Not Mains power quality should be
applicable that of a typical commercial or
hospital environment.
Not Mains power quality should be
applicable that of a typical commercial or

Not Mains power quality should
applicable be that of a typical commercial
or hospital environment. If the
user of the Model Smart Control
requires continued operation
during power mains interruptions,
it is recommended that the
Model Smart Control be powered
from an uninterruptible power
supply or a battery.
3 A/m Power frequency magnetic fields
should be at levels characteristic
of a typical location in a
typical commercial or hospital
environment.

IEC 61000-4-6 150 kHz to
80 MHz
Radiated RF 3 V/m 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.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones
a
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.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
b
Electromagnetic environment - guidance
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.
Recommended separation distance
d = 1,2
d = 1,2 80 MHz to 800 MHz
d = 2,3 800 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 electromagnetic site survey,
should be less than the compliance level in each
frequency range .

Interference may occur in the vicinity of equip-
ment marked with the following symbol:
