9. What does IP mean? The IP rating gives an “at a glance” method of recognizing the level of environmental protection that an enclosure gives the equipment/components contained within it. Ingress Protection (IP) ratings were developed by the European Committee for Electrotechnical Standardization (CENELEC) (the specification is fully described in Document IEC/EN 60529).

10. IP (Ingress Protection) standard table Protection against long periods of immersion under pressure. 8 Protection against the effect of immersion between 5.9“ and 39.4“ (15cm and 1m) 7 Protection against low pressure jets of water from all directions. Limited ingress permitted. 6 Totally protected againest dust. 6 Protection against low pressure jets of water from all directions. Limited ingress. 5 Protection against dust limited ingress. 5 Protection against water sprayed from all directions. Limited ingress permitted 4 Protection against solid objects up to 0.04“ (1mm) 4 Protection against direct sprays of water up to 60˚ from vertical. 3 Protection against solid objects up to 0.1“ (2.5 mm) 3 Protection against direct sprays of water up to 15˚ from the vertical. 2 Protection against solid objects up to 0.5“ (12 mm) 2 Protection against vertically falling drops of water. 1 Protection against solid objects up to 1.97“ (50 mm) 1 No protection 0 No protection 0 Protection from liquids Protection from solid objects or materials IP Ratings Table

11. AC Technology and our (IP) Ingress Protection Benefits Resistant to dust and moisture (IP 54) for outdoor use ” Protection from water that sprays against the equipment (casing) from all directions“ Second code number = 4: Protection levels (water) First code number = 5: Protection levels (solid parts / dust) ” Protection against harmful dust deposits. The penetration of dust is not completely prevented, but dust does not penetrate in quantities that will affect the function of the equipment“ The majority of our competitors have an IP rating of only 21 or less!
