1.9.2 Use of the ET 200M / S7-300 in a Zone 2 Hazardous Area
Zone 2
Hazardous areas are divided up into zones. The zones are distinguished according
to the probability of the existence of an explosive atmosphere.
Zone Explosion Hazard Example
2 Explosive gas atmosphere
occurs only seldom and for a
short time
Areas around flange joints with flat
gaskets in pipes in enclosed spaces
Safe area No • Outside zone 2
• Standard distributed I/O applications
Below you will find important information on the installation of the ET 200M
distributed I/O device and the SIMATIC S7-300 in a hazardous area.
Further Information
You will find further information on the ET 200M and the various S7-300 modules
