DANGER: Explosion hazard

If at least one terminal in the Inline station does not have ATEX approval for Zone 2,

the entire station must not be installed in this area.

In this case, install the station in a safe area.

Not all bus couplers support the operation of intrinsically safe I/O terminals.

Table 5-6 on page 49 shows which bus couplers can be used in combination with

intrinsically safe I/O terminals.

Check if the terminals you use are ATEX approved for Zone 2. Conformity is ex-

plained in the CE Declaration of Conformity. In addition, the terminals are marked

accordingly.

For an overview of Inline terminals for use in Zone 2 potentially explosive areas,

please refer to the application note AH EN IL EX ZONE 2.
