W Technicalappendix W. 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. Installation The general statements regarding standard applications are also valid for Ex applications. Accessories The accessories listed can used and included the ATEX certification.87.271282250000 2012/2013 . Additional information about using Weidmüller terminals intrinsically- safe circuits can requested from the manufacturer.

The continuous operating temperature to 60079-0 for the material KRG is 130 °C, for Wemid 120 and for the material °C.05 361 300 520 452.03 234 150 309 268.5  24  20.12  66  25 101  87.ATEX terminal blocks Design for i Terminals for intrinsically-safe circuits (“i“) are passive components. 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
