Storage condition: Fuses should be stored in their original boxes under typical warehouse conditions for elec- tromechanical products (free from any dirt and dust). Storage conditions should be no more then 70 percent relative humidity and in the -40 oC to +85 oC range. Work conditions: Work within the temperature -40 oC to +100 oC range. Installation conditions: The fuse should be mounted to busbar with 5pcs M12 socket set screws at each side, the screws according to ISO4026/DN913 or ISO4029/DIN916 are recommended. The studs must be tightened carefully applying a torque of 5-8 N.m, recommended nut tightening tor- ques is 35±4% N.m. Drawing: Technical parameter
