Electronic equipment, including power supplies, intended for use in unmanaged environments must be protected from the ingress of dust and water. International standard EN 60529 defines an IP (Ingress Protection) classification system showing the level of a product’s protection. Within the 2-digit IP number, the first digit refers to dust and solid objects, and the second to water. The higher the digit value, the better the protection.
IP First Number – Protection against solid objects

2 Protected against solid objects up to 12 mm, e.g. persons fingers.
3 Protected against solid objects over 2.5 mm (tools and wires).
4 Protected against solid objects over 1 mm (tools, wires, and small wires).
5 Protected against dust limited ingress (no harmful deposit).
6 Totally protected against dust.
