Use of the ET 200iSP distributed I/O device in device group I (mining) Category M2
The following conditions must be fullled if the ET 200iSP is used in device group I (underground
mining operations and their overground systems) Category M2:
CAUTION
Transport and storage of the ET 200iSP
• To avoid ignitable sparks, the power supply (PS) and the mounting rail of the ET 200iSP must
be packaged in shock-proof packaging for transportation and storage (e.g. for servicing)
and immediately removed from the hazardous area.
• The enclosure in which the ET 200iSP is installed must be approved for device group I,
category M2.
• Observe all other requirements concerning use of the ET 200iSP in the hazardous areas
given in this manual.
9.3 Electromagnetic compatibility, transport and storage conditions
Denition of EMC
Electromagnetic compatibility is the ability of electrical equipment to function satisfactorily in
its electromagnetic environment without inuencing this environment.
The ET 200iSP distributed I/O device also meets the requirements of the EMC law of the European
market. This requires that the ET 200iSP distributed I/O device meets the specications and
directives for electrical installation.
EMC in accordance with NE21
The ET 200iSP distributed I/O system complies with the EMC requirements of NEMUR directive
NE21.
Pulseshaped interference
The following table shows the electromagnetic compatibility of the ET 200iSP distributed I/O
device in relation to pulse-shaped interference variables.
