  • Associated product(s)

Product information
This entry contains all the SIMATIC HMI panels that have an FM certificate for the explosion protection standard. The FM certification is valid exclusively for North America.

Note
In Europe, the explosion protection guidelines in compliance withATEX are valid. More information on the panels that Siemens currently provides with ATEX certification is available in Entry ID: 291285.

  2. Current HMI panels with FM certificate
  3. Discontinued HMI panels with FM certificate
  4. Explanation of terms

Pay attention to the explosion protection ID on the back of the device before installing the panels. Panels mentioned in the certificate should not be used automatically in the hazardous areas with potentially explosive atmosphere. What counts here is the ID on the back of the device.

1. Information on FM certification
The classification of the explosion protection in the NEC (National Electric Code) is standard in the United States of America and that in the CEC (Canadian Electric Code) in Canada.

The hazardous areas/divisions with potentially explosive atmosphere are defined in the NEC 500. In addition, in the NEC 505, the hazardous areas with potentially explosive atmosphere are divided into zones in the same way as in ATEX and have practically identical types of protection. The specifications in the NEC 500 regulate conventional Ex classification (Class Division Model) and include the classification of the new zone model that is based on regulations in Europe and the IEC. Based on this, testing organizations like FM (and FMRC - Factory Mutual Research Corporation) create their own sets of standards.

2. Current HMI panels with FM certificate
The following panels have been tested in compliance with the FM certification NI Class I, Division 2, Group ABCD and Class I, Zone 2, Group IIC.

Note
Details about FM certification are available in the relevant certificates.

The panels in the following table are sold by Siemens (as at 05/2009).

4. Explanation of terms
In the following, we briefly explain only the relevant designations.

  • Nonincendive (NI)
    This type of protection is provided specially for Division 2 and specifies that during normal operation no sparks and no hot surface temperatures are generated. The type of protection is comparable with the type of protection "n" in compliance with EN 50021.
     
  • Class I, Division 2 (NEC 500)
    Areas where dangerous concentrations of flammable gases or vapors do not exist under normal operating conditions.
     
  • Class I, Zone 2 (NEC 505)
    Areas where dangerous concentrations of flammable gases or vapors do not exist under normal operating conditions.
     
  • Group A, B, C, D (NEC 500)
    The division into "Groups" refers to the hazardous materials:

    A = Air/gas mixture with acetylene
    B = Air/gas mixture with hydrogen
    C = Air/gas mixture with ethylene
    D = Air/gas mixture with propane
     
  • Group IIC (NEC 505)
    The division of the "Group" (NEC 505) is equivalent to the explosion group in the ATEX guidelines. Hydrogen is defined as a typical gas in explosion group IIC.
     
  • Temperature classes T*
    There are six different temperature classes that are specified in detail in compliance with NEC 500-3. The temperature class includes the highest permitted surface temperature of the apparatus and provides information on the ignition temperatures of the inflammable materials.
