Ingress Protection:
IP22
Solid particle protection: Hazardous parts are protected from touch by fingers and by
objects greater than 12 mm.
Liquid ingress protection: The protection withstands dripping water less than 15 degrees
from vertical.
The ingress protection has been tested by water drips equivalent to 3mm rain/minute for
10 minutes (2.5 minutes for each tilting direction).
