Guidance and manufacturer’s declaration – electromagnetic emissions
The device is intended for use in the electromagnetic environment specified below.The customer or the user of the device
should assure that it is used in such an environment.

equipment should be used no closer to any part of
the device including cables, than the
recommended separation distance calculated from
the
equation applicable to the frequency the
transmitter.
Recommended separation distance:
𝑑 = 0.35√𝑃
𝑑 = 1.2√𝑃
80 MHz to 800 MHz
𝑑 = 1.2√𝑃
800 MHz to 2.7 GHz
𝑑 = 2.3√𝑃
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,
should be less than the compliance level in each
frequency range.Interference may occur in the
vicinity of equipment marked with the following
symbol:
Note 1: 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.
f.
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 device is used exceeds the applicable RF
compliance level above, the device should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the device.
g.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
h.
Calibration for c
urrent injection clamps shall be performed in a 150 Ω system.
i.
If the frequency stepping skips over an ISM or amateur band, as applicable, an additional test frequency shall be used
in the ISM or amateur radio band. This applies to each ISM and amateur radio band within the specified frequency
range.
j.
Applicable to ME EQUIPMENT and ME SYSTEMS with RATED input current less than or equal to 16 A / phase and
ME EQUIPMENT and ME SYSTEMS with RATED input current greater than 16 A / phase.
