In summary, Ingress protection is the level of protection against the intrusion of solid objects, liquids, dust, and accidental contact with electrical enclosures inside a mechanical casing. This rating gives users a more detailed understanding of general terms such as waterproof or water-resistant. The numerical digits represent conformity with the conditions outlined in the Ingress Protection Marking. For example, an electrical enclosure rated IP68 is completely protected against dust and cannot be damaged or become unsafe during permanent immersion in water. The importance of an IP68 rating on ebm-papst products is to ensure the highest level of protection of the electronics inside the enclosure against foreign objects and water, while also protecting the user against potentially harmful contact.
