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).
