Maximum Temperature Specifications For Ex Use - Siemens MASS 2100 Operating Instructions Manual

Safety notes
2.4 Use in hazardous areas
● Sensor and transmitter are connected to the potential equalization throughout the
hazardous area.
● EN/IEC 60079-14 is considered for installation in hazardous areas.
Further information and instructions including approval-specific special conditions for safe use
in Ex applications can be found in the certificates on the accompanying literature CD and at
the product web page (www.siemens.com/FC430).
Laying of cables
Explosion hazard
Cable for use in hazardous areas must satisfy the requirements for having a proof voltage of
at least 500 V AC applied between the conductor/ground, conductor/shield and shield/ground.
Connect the devices that are operated in hazardous areas as per the stipulations applicable
in the country of operation.
Field wiring installation
Ensure that the national requirements of the country in which the devices are installed are
met.
