1.1 Explosion Protection Standards
There are various standards for explosion protection in each region. Therefore, when we try to
use equipment in a certain region, it needs to be approved by the explosion protection standards
adopted in the region. ProSafe-RS/ProSafe-RS Lite, a global product, has been certied
according to the standards adopted in North America and Europe.
The table below lists the explosion protection standards that ProSafe-RS/ProSafe-RS Lite
complies and their certication authorities. As shown in the table, ProSafe-RS/ProSafe-RS Lite
equipment comply with the FM Approval Standard for Non-Incendive equipment and satisfy the
protection ATEX Ex “ec” or ATEX Type “n”. Also the ProSafe-RS/ProSafe-RS Lite equipment
have acquired UKEX Ex “ec” or UKEX Type “n”.Therefore they can be installed in Zone 2 or
Division 2 hazardous areas. This chapter mainly describes the explosion protection compliance
of ProSafe-RS/ProSafe-RS Lite equipment.
