Appendix A - Internal Protection
Parker has conducted testing to determine the degree to which the positioner is protected by using a
British standard called an Ingress Protection Rating (IP Rating) . The MX45S has an IP 10 protec-
tion rating.
Definition
Reference: British standard EN 60529 : 1992
This standard describes a system of classifying degrees of protection provided by enclosures of
electrical equipment. Standardized test methods and the establishment of a two digit numeric rating
verify the extent of protection provided against access to hazardous parts, against ingress of solid
foreign objects, and against the ingress of water.
First Number – The first number indicates protection of persons against access to dangerous parts
and protection of internal equipment against the ingress of solid foreign objects.
1 - Protection against access to hazardous parts with the back of a hand, and protected
against solid foreign objects of 50 mm diameter and larger.
Second Number – The second number indicates protection of internal equipment against harmful
ingress of water.
0 - No special protection provided.
Note: Number Indicators above represent only a partial list of IP Rating specifications.
