Technical Drawing

ic audio logo

DK-EX 30/T
ic audio loudspeakers are tested and classified according to the IEC standard 60529 (degree of protection by enclosure) against the penetration of foreign objects and moisture. The classification is conforming to standards through characterization with a fixed code. This code consists of the letters IP (International Protection) followed by two digits. The first digit indicates the degree of protection against dust and the second digit the degree of protection against water. Please note that the testing of the products has been carried out in laboratory conditions which are not always 100% comparable with the conditions of different installation environments. This protection can be reduced due to normal wear and tear depending on the installation environment.

The IP66 protection rating was confirmed as part of the Ex certification carried out by TÜV SÜD in accordance with EN IEC 60079-0.

Installation note: Install in accordance with EN/IEC 60079-14. Do not open the unit in a potentially explosive atmosphere. Repairs to flame-proof joints are not permitted. Install only in locations with low mechanical risk or where additional mechanical protection is provided.
