2 When things start hotting up: Electrical switching takes place every time a control system assumes control or automatic functions. Remote control switches for pulse control or Insta contactors switch the loads. The range of different demands ask for a broad spectrum of different contacts and rated currents. 6/2 7/2

11 Overview Scope The scope of the EC Directive Machines is no longer restricted to industrial machinery, but now covers virtually all machines for use in all areas of commercial and private trade and industry and applies to all Stationary Movable, Hand-held, Mobile Machine tools and processing machines Prime movers and production machines Risk analysis and selection of a suitable category Engineers and operators assume responsibility for the correct risk assessment. It is difficult to make a quantitative assessment of the risk, so that when selecting the category, the reasonable risk can be determined within a broad band width. Risk parameter S: seriousness of injury minor injury serious and irreversible injury of one or several persons or death of a person Benefits Acc. to the 98/37/EC EC directive for machines Safety category 4 acc. to DIN EN Acc. to the 98/37/EC EC directive for machines Selection and ordering data Risk parameter F: Risk parameter P: frequency and possibility of duration avoiding injuries rarely to frequently frequently to constantly possible under certain circumstances hardly possible possible under certain circumstances hardly possible 5TT5 2 EMERGENCY-STOP modules Compressors Operating and packaging machines Machines in underground mining Earthmoving machines and harvesters Hoisting equipment Floor conveyors Machines for lifting persons Plants Interchangeable equipment, such as snow ploughs and mountable sweeping devices This becomes clear if you select "F2 - frequently to continuous" instead of "F1 - rarely to frequently", for the risk parameters "F - Frequency and duration" when drawing up a risk graph (see image). The whole band width of safety categories may lie between the assessment of "often" and "frequently". Categories B Safety category 4 acc. to DIN EN Electrical isolation between electric circuit and control LED display for operation and circuit state I2_08404a preferred categories for reference points possible category which requires additional measures with regard to the risk overdimensioned measures with regard to the risk Version U e I e U c MW Order No. Price PG Weight 1item PS*/ P. unit V AC A V AC 1 item kg Items EMERGENCY-STOP module, mounting depth 55 mm TT TT5 200 * You can order this quantity or a multiple thereof.
