ATEX/IEC Ex ic IC MODELS 311 AN/GN - THIRD PARTY AGENCY APPROVAL CODE: AN-S

Oct 24, 2026

Uploaded by dhado

Third-party agency approval information for ATEX/IEC Ex ic IC models 311 AN/GN, including a specific approval code (AN-S) and safety installation guidance. The controlled drawing specifies safe area and hazardous area wiring and shunt switch connection requirements, with conditions for intrinsically safe circuits (Uo≤Ui, Io≤Ii, Co≤Ci+Ccable, Lo≤Li+Lcable). It includes entity parameters for an Ex ic IIC T5 device (e.g., Ui=28V, Ii=100mA, Ci=27.2nF, Pi=0.7W) and notes on certified barrier and voltage-free contact wiring.

FAQs

What does the approval code “AN-S” refer to?

It is the third-party agency approval code associated with the ATEX/IEC Ex ic IC models 311 AN/GN shown on the drawing.

What core electrical limits must be satisfied for the circuit (entity parameters)?

The document specifies intrinsic safety relations including Uo≤Ui, Io≤Ii, Co≤Ci+Ccable, and Lo≤Li+Lcable, along with corresponding parameter values listed for the device.

What wiring restriction is stated for the shunt switch connections?

Shunt switch wiring must be non-incendive and connected to a voltage-free contact, using a certified relay contact barrier with a voltage-free contact.
