Service conditions AUMA devices are used worldwide; in all climate zones, in industrial plants of all kinds under special local ambient conditions. AUMA devices have to operate reliably and for a long time under any conditions without requiring major maintenance work. For this very reason, AUMA has focussed on making AUMA devices resistant to the most unfavourable conditions and have adapted their protective measures to the state-of-the-art technology. Enclosure protection IP 67 AUMA actuators conform to enclosure protection IP 67 according to EN 60 529. IP 67 means protection against immersion up to max. 1 m head of water for max. 30 minutes. IP 68 AUMA actuators are available with improved enclosure protection IP 68 according to EN 60 529. IP 68 means protection against submersion up to 6 m head of water for max. 72 hours. During submersion up to 10 operations are permissible. In order to guarantee the enclosure protection IP 68, suitable cable glands must be used. They are not part of the standard supply, but can be provided by AUMA on request.

Corrosion protection/colour Standard (KN) The standard AUMA corrosion protection KN is a high quality coating. This is suitable for outdoor installation and for slightly aggressive atmospheres with a low level of pollution. KS AUMA recommends this corrosion protection class for installation in occasionally or permanently aggressive atmospheres with a moderate pollutant concentration. KX AUMA recommends this corrosion protection class for installation in aggressive atmosphere with high humidity and a high pollutant concentration. Colour The standard colour of the finish coating is silver-grey (similar to RAL 3037). Other colours are available on request. Explosion protection For the installation of actuators in potentially hazardous or explosive areas, special protective measures are required. These are stipulated in the European Standards EN 50 014, 50 018, and 50 019. The PTB (Physikalisch Technische Bundesanstalt, the German national test authority) and the BVS (German Mining Test Facility) as European test authorities have certified the conformity of the equipment with the mentioned standards.
