Guidance and manufacturer's declaration – electromagnetic immunity
The Stöckert Heater-Cooler System 3T is intended for use in the electromagnetic environment specified below. The customer or
the user of the Stöckert Heater-Cooler System 3T should assure that it is used in such an environment.

Electromagnetic environment - guidance
Portable and mobile RF communications equipment should be
used no closer to any part of the Stöckert Heater-Cooler System
3T, including cables, than the recommended separation distance
calculated from the equation applicable to the frequency of the
transmitter.
Recommended separation distance:
Conducted RF
IEC 61000-4-6
3 V
eff
150 kHz to
80 MHz
10 V
eff
150 kHz to
80 MHz
Radiated RF
IEC 61000-4-3
3 V/m
80 MHz to
2.5 GHz
10 V/m
80 MHz to
2.5 GHz 80 MHz to 800 MHz
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 metres (m).
Field strengths from fixed RF transmitters, as determined by an
electromagnetic site survey
a
, should be less than the
compliance level in each frequency range.
b
Interference may occur in the vicinity of equipment marked with
the following symbol:
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 Stöckert Heater-Cooler System 3T is used exceeds the applicable RF compliance level
above, the Stöckert Heater-Cooler System 3T should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the Stöckert Heater-Cooler System 3T.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
