2.1.3 Operating Requirements 
The devices have been developed to meet the following standards for EMC, climatic and 
environmental requirements: 
Standard  Content 
IEC/EN 61131-2  Programmable controllers, Part 2 
Equipment requirements and tests 
IEC/EN 61000-6-2  EMC 
Generic standards, Parts 6-2 
Immunity for industrial environments 
IEC/EN 61000-6-4  Electromagnetic Compatibility (EMC) 
Generic emission standard, industrial environments 
Table 1:  Standards for EMC, Climatic and Environmental Requirements 
When using the safety-related HIMax control systems, the following general requirements 
must be met: 
Requirement type  Requirement content 
Protection class  Protection class II in accordance with  IEC/EN 61131-2 
Pollution  Pollution degree II in accordance with IEC/EN 61131-2 
Altitude  < 2000 m 
Housing Standard: IP20/IP00 
If required by the relevant application standards (e.g., EN 60204), 
the device must be installed in an enclosure of the specified protec-
tion class (e.g., IP54).
