Where necessary, end plates or partitions must installed as described ensure adherence to creepage and clearance distances for Ex applications.

Taking into account further safety factor according 60079-0, we reach the following definitions: Temperature class Ambient temperature T6 -50 +40 °C T5 -50 +55 °C The permitted nominal current must be reduced accordingly the actual ambient temperature higher.04 167  95 232 201. Certified for the European Directive 94/9/EG ATEX – Electrical data The values for current-carrying capacity as stated the catalogue are based on an ambient temperature 40°C.271282250000 2012/2013 .5  17. When loaded with the rated current 10%, the temperature the current bar of the modular terminal may not rise more than K. important sure that two the same cross-sections are used below the rated cross-section.

Therefore, for use intrinsically-safe circuits, you not need EC-standard examination certificate.5  15. Clamping two conductors in Ex applications For the terminals from our W-series, it is normally permitted connect two wires per clamping position long as this permitted accordance with the type test according IEC 60947-7-1 or 60947-7-2. The blue terminals are recommended for clear labelling and easy recognition. Additional information about using Weidmüller terminals intrinsically- safe circuits can requested from the manufacturer.
