4.2 Climatic Requirements
IP-protection type (certified) IP 68 (for fan only, not for connector if applicable) **)
Humidity requirements humid temperature, cyclic; according to DIN EN 60068-2-38, 10
cycle and condensation water check; according to DIN EN ISO
6270-2, 14 days
Salt fog requirements None
Permitted application area:
The product is for the use in partial sheltered rooms or open, roofed areas. Direct exposure to water is allowed
provided that this does not prevent the normal operation. Saline ambient conditions must be avoided.
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)
with the letter K.
Short description of the IP-protection type:
Solid particle Protection: Dust tight.
Protection against deliberate contact: Protected against contact to hazardous parts with a wire.
Protection against water: The fan test according to IP68 (Based on IEC 60529), is conducted in non-operating mode.
The fan is tested by a complete immersion in water for a period of 2h at a water-level of 1,2m. Electrical connections
are not immersed since they are customer specific.
Please require severity levels and specification parameters from the responsible development departments.
4.3 EMC
Kind Electrostatic Discharge Immunity Test
