Mounting and installation 7.1 Dimensions / fastening dimensions Dimensional Drawings (All Dimensions in mm / [inches]) - Subject to Alterations 0571E00 851/01 fuse element 851/0 fuse element 7. Mounting / dismounting, operating position The fuse element must only be installed, if it is fitted in an enclosure, that meets the requirements of an approved type of protection, according to IEC / 0079-7, e.g. "Increased safety e". During installation of the component in an enclosure, that meets the requirements of the type of protection "Increased safety e", the clearance and creepage distances, according to IEC/ 0079-7, must be adhered to. NOTICE Overheating A too short distance between individual components can cause overheating. Due to thermal reasons, a minimum distance of 9 mm has to be observed when several components are connected together. Fasten the device to the mounting holes, provided for this purpose, using suitable screws and accessories (see dimensional drawings). 057E00 When mounting the component, ensure presence of a flat surface. The operating position is optional. 195 / 8510300 01-03-0 BA00 III en 0 Fuse base with fusible link Series 851 9
