For that reason emitted interference tests are required. CE marking The manufacturer responsible for CE labelling accordance with the corresponding Directive.1 lEC 60947-1. Pollution severity IEC 60947-7-1 The pollution severity specifies the influence solid, liquid gaseous foreign matter that could reduce the electric strength the specific surface resistance.5 4..+40 °C, average value over +35 °C • Attitudes 2000 above sea level • Relative humidity +40 °C, 90 +20 °C W Technicalappendix W. This printed the packaging. Rated voltage IEC 60947-7-1 The rated voltage modular terminal is the rated insulation voltage which the insulation tests and creepage distances are based.5 2.. This applies exclusively terminal blocks with multiple connection levels (multi-tier terminals) and test- disconnect terminals for which a current reduction permissible. Cable connectors from V∼/75 fulfil the fundamental safety requirements stipulated the Low Voltage Directive 2006/95/EC. designed to guarantee the free movement of goods within Europe.0 A 17. For that reason immunity tests are required. (EMC) Interference immunity Terminals used applications that fall under the scope of the IEC/EN 60947-7-1 are immune to electromagnetic disturbances.131282250000 2012/2013 .5 41 mm2 10 35 A 101 125 mm2 50 120 A 150 192 232 269 mm2 150 185 240 300 A 309 353 415 520 Conventional free-air thermal current (Ith) The conventional thermal current in free air (Ith) the largest test current for warming tests open equipment in the free air, see 4. Emitted interference Terminals used applications that fall under the scope the IEC/EN 60947-7-1 not generate electromagnetic disturbances. non-permissible rise the temperature the terminal occurs conjunction with these rated currents: mm2 1. Operating conditions The modular terminals can used in the following standard conditions: • Ambient temperature °C. The minimum clearance defined in IEC 60947-7-1 conjunction with the rated impulse withstand voltage. They are determined according IEC 60664-1. The reduced current values are then designated conventional thermal current free air (Ith). Rated impulse withstand voltage IEC 60947-7-1 This the value surge voltage to which the modular terminals can be subjected and which the clearances to IEC 60947-1 IEC 60664-1 are based. Pollution severity has been specified for modular terminals for industrial applications: the occurrence of conductive contamination dry, non-conductive contamination which becomes conductive because condensation expected.0 6. This confirms conformance with the Directive for the attention of government authorities.Norms, Standards, Terms Rated current IEC 60947-7-1 Test currents are assigned the rated cross-sections accordance with IEC 60947-7-1.2. Together with the appropriate technical documentation declarations conformity are kept available for review the responsible monitoring authority.3. If the test current not required be reduced for the associated rated cross-section, then the term remains “rated current”
