ＮＩＳＳＥＩ ＣＯＲＰＯＲＡＴＩＯＮ E6581815I-199. Measures to satisfy the standards9.1 How to cope with the CE directiveIn Europe, the EMC directive and the low-voltage directive, which took effect in 1996 and 1997, respectively,made it obligatory to put the CE mark on every applicable product to prove that it complies with the directives.Inverters do not work alone but are designed to be installed in a control panel and always used in combinationwith other machines or systems which control them, so they themselves are not considered to be subject to theEMC directive. However, the CE mark must be put on all inverters because they are subject to the low-voltagedirective.The CE mark must be put on all machines and systems with built-in inverters because such machines andsystems are subject to the above directives. It is the responsibility of the manufacturers of such final products toput the CE mark on each one. If they are "final" products, they might also be subject to machine-related directives.It is the responsibility of the manufacturers of such final products to put the CE mark on each one. In order tomake machines and systems with built-in inverters compliant with the EMC directive and the low-voltage directive,this section explains how to install inverters and what measures should be taken to satisfy the EMC directive.We have tested representative models with them installed as described later in this manual to check forconformity with the EMC directive. However, we cannot check all inverters for conformity because whether or notthey conform to the EMC direction depends on how they are installed and connected. In other words, theapplication of the EMC directive varies depending on the composition of the control panel with a built-ininverter(s), the relationship with other built-in electrical components, the wiring condition, the layout condition, andso on. Therefore, please verify yourself whether your machine or system conforms to the EMC directive.9.1.1 About the EMC directiveThe CE mark must be put on every final product that includes an inverter(s) and a motor(s). EMC directive2004/108/ECThe EMC standards are broadly divided into two categories; immunity- and emission-related standards, each ofwhich is further categorized according to the operating environment of each individual machine. Since invertersare intended for use with industrial systems under industrial environments, they fall within the EMC categorieslisted in Table 1 below. The tests required for machines and systems as final products are almost the same asthose required for inverters. |
