Furthermore, the series are tested through the Schweizerischer Elektrotechnischer Verein<br />

certificate A. no. 97.1 10387.01<br />

and approved through the Schweizer Eidgenössische Starkstrominspektorat (Swiss Confederate Power Current Inspectorate)<br />

approval no. 98.5 51477.01, 95.1 11107.07.<br />

The reports on the test <strong>for</strong> intended use in hazardous areas are available. The certificates of con<strong>for</strong>mity and the EC certificates of sample test<br />

issued <strong>for</strong> the individual types are to be taken from the approval summary.<br />
