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 402XE and 403XE have an
IP 20 protection rating when equipped with hard cover (R1 option).
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.
2

Protection against access to hazardous parts with fingers, and protected against solid for-
eign objects of 12.5 mm diameter and larger.
3
-
Protection against access to hazardous parts with a tool, and protected against solid for-
eign objects of 2.5 mm diameter and larger.
Second Number: The second number indicates protection of internal equipment against harmful
ingress of water.
