Instructions for European EMC Conformity 

 

 

WARNING

 

 

 

It is the responsibility of the user of this equipment to provide electromagnetic shielding, filtering and isolation 
which is necessary for EMC compliance to Directive 2014/30/EU. The equipment must therefore be operated in 
a shielded area which provides a sufficient level of attenuation to meet the radiated emissions and immunity 
specifications. The following minimum levels are suggested for use in accordance with the rated power of the 
equipment. 

 

Rated Power 

Minimum shielding attenuation 

100 watts 

50 dB 

101 - 1000 watts 

60 dB 

1001 - 10,000 watts 

70 dB 

 
Since this equipment is designed to generate high levels of Radio Frequency energy, it is also essential that the 
user read and follow the “Instructions for Safe Operation” in this manual. If other equipment is operated in the 
shielded room it may be disturbed by the amplifier. 

 

 

ACHTUNG

 

 

 
Der Benutzer dieses Gerätes ist dafür verantwortlich, daß die elektromagnetische Abschirmung und Filterung 
gewährleistet ist, welche gemäß Richtlinie 2014/30/EU  notwendig ist. Das Gerät muß deshalb in einem 
geschirmten Raum betrieben werden, welcher eine ausreichenden Schirmung bietet, um die Emissions-  und 
Störfestigkeitsspezifkation einzuhalten. Es werden folgenden Minimalwerte der Schirmdämpfung und Filterung 
in den unterschiedlichen Leistungsklassen empfohlen. 

 

Hochfrequenzleistung 

min. Schirmdämpfung 

100 Watt 

50 dB 

101-1000 Watt 

60 dB 

1001-10.000 Watt 

70 dB 

 
Falls andere elektrische oder elektronische Geräte gleichzeitig mit dem Gerät betrieben werden, kann es zu 
Beeinflussungen kommen. Da das Gerät zur Erzeugung von Hochfrequenzenergie dient ist es  daher auch 
unbedingt notwendig, daß der Benutzer die Sicherheitsvorschriften in der Bedienungsanleitung liest und einhält. 

 

 

AVERTISSEMENT 

 

 

Il est de la responsabilité de l'utilisateur de cet équipement d'assurer la protection électromagnétique, le filtrage 
et l'isolation nécessaires, afin de se conformer à la directive 2014/30/EU concernant la C.E.M. Par conséquent, 
cet équipement doit être mis en fonctionnement dans une enceinte d'atténuation suffisante pour satisfaire aux 
spécifications d'émissivité et de susceptibilité. Pour une utilisation conforme, les niveaux d'atténuation 
minimums suivants sont suggérés en fonction de la puissance de sortie de l'équipement: 

 

Puissance de sortie 

Atténuation minimum de l'enceinte 

100 Watts 

50 dB 

101 à 1.000 Watts 

60 dB 

1.001 à 10.000 Watts 

70 dB 

 
Puisque cet équipement est destiné à générer de forts niveaux R.F., il est essentiel que l'utilisateur se conforme 
aux instructions de sécurité indiquées dans ce manuel. Tout autre équipement en fonctionnement dans la cage de 
Faraday peut-être perturbé par 1'amplificateur.
