Issue:
Ingress or international protection (IP) rating is required for SMC, SMT or SMX series Smart-UPS.

Product Line:

Cause:
IP ratings are used to determine how large an object, or liquid, may pass through the side panels, or roof, of an enclosure.

5 = Dust protected
6 = Dust tight

2nd number of the rating can range from 0-8 and indicates degree of protection with respect to harmful ingress of water.

0 = Not protected
1 = Protects against dripping water
2 = Protects against dripping water of +- 15 degree angle
