IDC connection for: • Standard DIN rail terminal blocks • Duo DIN rail terminal blocks • Multi-tier blocks • Disconnect blocks • Fuse blocks • Hybride terminal blocks taris connects copper wires easily, fast and safely taris for TS 35 n no wire stripping, no ferrules n no special tools – a screwdriver is all you need n 60 % time savings = reduced costs n low packing density (5 mm wide) n optical control of the switching state n cross sections up to 1.0 mm2 and 2.5 mm2 All Wieland Components which require Ageneral certification are Acertified, and identified with the Alogo. Technical information • The information regarding cross sectional area and connection types pertains to unprepared wires without ferrules! Ferrules are not necessary for secure connection. Whenever ferrules are used, make sure that the tools specified by the manufacturer are used exclusively. • The voltage ratings apply to the terminals in their intended application. When different products are mounted adjacent to each other, the proper isolation distances must be adhered to. • If the ground blocks of the taris product family are not used in block assemblies, but are mounted to the rail as single terminal blocks, end clamps have to be used. • A detailed description of technical data, the standards requirements, and the application conditions are available under facts & DATA. ATEX regulation • For the use of DIN rail terminal blocks in Ex areas, the regulations of EN60079-0 apply; whereas for increased safety Exe the 60079-7 must be followed. For an approximation of the laws of the EU member states, directive 94/9/EG was created, which is generally known as ATEX 100a and which is the basis for harmonization in this field. ATEX stands for ”atmosphere explosive” while 100a refers to the corresponding article of the EC contract. • Directive ATEX 100a applies for protection against dust and gas explosions in all industrial Ex areas and in mining. The testing and certificating institutes named in directive ATEX 100a must follow accreditation procedures which are the same all over Europe. • In accordance with EN 60079-0/60079-7 and ATEX 100a, these certifying institutes write out EC certificates for prototype tests. These prototype test certificates for components together with the corresponding quality system certification of the supplier are required to obtain the so-called ATEX approval. • In combination with theOmark, the markings of the Wieland terminal blocks have the following meaning: O Identification II Device group 2 Category G D Areas KEMA Name of testing institute ATEX... Certifcate, year of testing, number Mounting instructions for Ex e applications • If feed-through blocks are mounted directly adjacent to other feed-through blocks of a different size, or directly adjacent to ground blocks, the open side of the block group of the same type must be covered by an end plate or partition. • IIf adjacent DIN rail terminal blocks are jumpered or if jumpered DIN rail terminal blocks are positioned next to unjumpered DIN rail terminal blocks, a partition plate must be inserted between the individual terminal block groups or at the beginning and end of a laterally or longitudinally connected terminal block (group) in order to meet the specified isolation distances. Notched out and jumpering cross connectors cannot be used in Ex areas. • If the terminal blocks are combined with other certified series and sizes and when their accessories are used, the required creepage distances and clearances must be adhered to. • The feed through terminal blocks and protective conductor terminal blocks are suitable for enclosures for use in explosive gas atmospheres or for use in the presence of combustible dust. For explosive gas atmospheres these enclosures must satisfy the requirements of EN 60079-0 and EN 60079-7. For combustible dust these enclosures must satisfy the requirements of EN 61241-0 and EN 61241-1. • The indicated values for the current carrying capability refer to a maximum ambient temperature of 40°C. When the terminal blocks are loaded with the maximum rated current the temperature rise will be max. 40 K. DQS certification for all company sectors • Quality standard as per DIN ISO 9001 in Development, Production and Assembly • Continued control of the quality standard by means of regular internal and external quality audits • Compatible with certificates of other countries: – BSI Certificate, Great Britain – SQS Certificate, Switzerland – Aib-Vincotte Certificate, Belgium – ÖQS Certificate, Austria
