Special Conditions for ATEX Zone 2 Use (Marking X)

• Install the device in a housing with at least IP54 protection according to EN 60079-0

• Do not disconnect or open when powered

• Prevent disconnection of plugs or housing parts by using a housing with a special lock (e.g., control cabinet)

• Use additional strain relief for cables in front of all plugs

• Prevent electrostatic charging of the housing with appropriate installation measures

• Ambient temperature: -5°C ≤ Ta ≤ +50°C

• Protect the device from UV radiation and any shock loading

• Seal unused inputs and outputs with protective caps ISK-M8 and ISK-M12 (not included in scope of delivery)

• Device may only be used in an environment with minimum pollution degree 2 (IEC 60664-1)

• The discharge of electrostatically charged parts can lead to ignitable sparks – prevent electrostatic charging by taking appropriate installation and cleaning measures 

Intrinsically Safe Input Option

The MPA-FB-VI can be equipped with an input module CPX-P-8DE-N-IS, which provides 8 digital NAMUR inputs for intrinsically safe wiring, recognisable by the existing blue identification . The non-intrinsically safe version is CPX-P-8DE-N, recognisable by the lack of blue identification . When the intrinsically safe module is used, the ATEX identification becomes II 3(G) Ex ec [ia Ga] IIC T4 Gc X .
