Electromagnetic Compatibility Information

Table 1

Guidance and manufacturer’s declaration – electromagnetic emissions

The IH 25/1 is intended for use in the electromagnetic environment speciﬁed below. The customer or the user of the IH 25/1 should assure

that it is used in such an environment.

Emissions Compliance Electromagnetic environment – guidance

RF emissions CISPR 11 Group 1 The IH 25/1 uses RF energy only for its internal function. Therefore, its RF emis-

sions are very low and are not likely to cause any interference in nearby electro-

nic equipment.

RF emissions CISPR 11 Class B The IH 25/1 is suitable for use in all establishments, including domestic esta-

blishments and those directly connected to the public low-voltage power supply

network that supplies buildings used for domestic purposes.

Harmonic emissions IEC 61000-3-2 Class A

the user of the IH 25/1 requires continued

operation during power mains interruptions,

it is recommended that the IH 25/1 be pow-

ered from an uninterruptible power supply

or a battery.

Portable and mobile RF communications equipment should be used no closer to any part

of the IH 25/1, 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 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 aected by absorption and reﬂection from

structures, objects and people.

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 electromagne-

tic environment due to ﬁxed RF transmitters, an electromagnetic site survey should be considered. If the measured ﬁeld strength in the

location in which the IH 25/1 is used exceeds the applicable RF compliance level above, the IH 25/1 should be observed to verify normal

operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the IH 25/1.

Over the frequency range 150 kHz to 80 MHz, ﬁeld strengths should be less than 3 V/m.
