Information on the documentation
Note
Higher-priority documentation
The information for the specific components takes precedence over the information in this
documentation. The statements in the product information always takes precedence over all
other information.
Operating conditions
The ET 200SP HA must be installed in a suitable enclosure which ensures at least IP 54 degree
of protection according to EN 60529. Use a safety enclosure that meets the requirements
regarding spread of fire and exhibits an appropriate strength according to UL61010-1 and UL
61010-2-201. Observe the applicable ambient conditions when using the ET 200SP HA. The
ET 200SP HA may only be used in an environment with no more than pollution degree 2 (as
defined in EN 60664‑1).
The ET 200SP HA distributed I/O system is designed for stationary use in weather-proof
locations. The operating conditions exceed requirements according to DIN IEC 60721‑3‑3:
● Class 3M3 (mechanical requirements)
● Class 3K3 (climatic requirements)
Use with additional measures
The described components may not be used without additional measures:
● At locations with a high degree of ionizing radiation
● In harsh operating environments caused, for example, by:
– Accumulation of dust
– Corrosive vapors or gases
– Strong electrical or magnetic fields
● In installations requiring special monitoring, for example:
– Elevator systems
– Electrical systems in potentially hazardous areas
An additional measure, for example, can be installation in a cabinet or enclosure.
