Design guide for using the AF model

The AF model is not designed to be wired directly. It must be connected to an Ex e or Ex d enclosure using certified bushings. See the guidance below for proper installation:

Connecting to an Ex e Enclosure

To connect an IDC24-AF Ex d (flameproof) enclosure to an Ex e (increased safety) enclosure:

  • Use certified components that are suitable for explosive environments.
  • Ensure all seals and connections preserve the integrity of each enclosure's protection type.

Connecting to an Ex d Enclosure

To connect an IDC24-AF Ex d (flameproof) enclosure to another Ex d enclosure:

  • Use certified components rated for explosive environments.
  • Install flameproof glands on both enclosures and ensure they are properly sealed to contain any internal explosion, preventing its transmission to the external environment.
