Degree of protection



Definitions

According to IEC/EN 60529, the degree of protection is indicated by an IP code where the
first numeral means protection against ingress of solid foreign objects, and the second
numeral protection against ingress of water. The IP codes of the standard cabinet and
options covered in this manual are defined below.
IP code
IP22 against ingress of solid foreign objects >
12.5 mm diameter *
IP42 against ingress of solid foreign objects > 1 mm
IP54 dust-protected
* meaning for protection of persons: against access to hazardous parts with finger

IP22 (standard)

The degree of protection of the standard drive cabinet is IP22 (UL type 1). The air outlets
at the top of the cabinet and the air inlet gratings are covered with metallic gratings. With
doors open, the degree of protection of the standard cabinet and all cabinet options is
IP20. The live parts inside the cabinet are protected against contact with clear plastic
shrouds or metallic gratings.
