3. Wiring & Installation


Connection Diagram:




  • Live (L) → Brown wire




  • Neutral (N) → Blue wire




  • Ground (PE) → Green/Yellow wire




Installation Steps:




  1. Isolate Power: Ensure the circuit is de-energized.




  2. Secure Cable Glands: Use ATEX-certified cable glands (e.g., PG16).




  3. Torque Terminal Screws: Typically 1.2–1.5 Nm (avoid over-tightening).




  4. Seal Threads: Apply silicone grease to enhance IP rating.







4. Applications




  • Oil & Gas: Drilling rigs, refineries.




  • Chemical Plants: Solvent handling zones.




  • Mining: Underground equipment power supply.




  • Grain Processing: Combustible dust environments.







5. Certifications & Compliance




  • ATEX 2014/34/EU (EU Directive)




  • IECEx (International)




  • UL/cUL (North America, if dual-certified)




  • GOST-R (Russia/CIS)
