*) Permittet application area:
The product is for the use in open and unsheltered areas. Direct exposure to water as well as saline ambient
conditions are allowed provided that this does not prevent the normal operation.
Pollution degree 3 (according DIN EN 60664-1)
It occurs conductive pollution or dry non-conductive pollution which becomes conductive due to condensation.
**) The specification of the IP protection refers to the conditions mentioned in certification of the fan. The above
mentioned short description of the protection scope is not final. For detailed information of the respective protection
scope and definitions, see certification as well as DIN EN 60529 (protection by housings) and ISO 20653 (for vehicles)
