Conditions of Application
1. Level switch type 2100E should be used according to the given Ex-marking, requirements of CU TR 012/2011,
GOST 30852.13-2002 (IEC 60079-14:1996), current “Electrical plant arrangement rules” (PUE, art. 7.3),
“Technical maintenance rules for electrical plants” (PTEEP, art. 3.4), other normative documents regulating
application of electrical equipment in explosive areas, and manufacturer’s instruction manual.
2. Potential Ex application areas of level switch, categories and groups of explosive gas and vapors mixtures with air
– according to requirements of GOST 30852.9-2002 (IEC 60079-10:1995), GOST 30852.11-2002 (IEC
60079-12:1978) and “Electrical plant arrangement rules” (PUE, art. 7.3).
3. Level switch must be used with approved cable glands and plugs that provide the required type and level of
protection and ingress protection.
4. Sign «X» after the Ex mark means that the electrical switch type 057-07 ** as part of an electronic module
comprising a level switch comes with a permanently attached cable. Connecting the free end of the cable to the
external device should be in accordance with the operating instructions and the requirements of GOST
30852.13-2002.
5. Changes in controller construction, concerning the explosion means, should be approved by Accredited Testing
Body.
