EN 55103-2:1996

This standard for EMC immunity requirements applies to professional audio, video, audio-visual and entertainment lighting control apparatus as defined in clause 4 intended for use in the environments described in clause 5. This includes the digital apparatus defined in 4.5 and sub-assemblies, see 7.4. Disturbances in the frequency range 0 Hz to 400 GHz are covered, but requirements are not established over the whole of that range. NOTE 1 : In annex C, information is included on infra-red radiation in the wave length range 0,7æm to 1,6æm. Fault conditions of source or victim apparatus are not taken into account. Apparatus as defined in 4.4, 4.5 and 4.6 may be operated with any source of power. NOTE 2: Sources of power may include, for example: . the public low-voltage supply; . private supplies with similar characteristics; . a d.c. source provided specifically for the apparatus; . batteries internal to the apparatus; . stand by generators. NOTE 3: In special cases, for instance if it is intended to use a hand-held transmitter in proximity, additional mitigative measures may have to be employed to increase the electromagnetic Immunity further, beyond the specified limits. This standard does not apply to: . consumer apparatus . apparatus specifically designed for security systems . apparatus designed to radiate electromagnetic energy for radio communications purposes
