Replacing a fuse link
When the fuse link is blown, it is recommended to replace the whole fuse plug with a spare one to avoid touching the hot fuse link. Spare fuse plugs are readily available if you have installed a cassette with fuse plugs on the DIN rail.
BURN HAZARD: A blown fuse link can have a temperature above 100°C. Never touch it directly with your fingers.
Step 1
Switch OFF.
Step 2
Eject the fuse plug. Recycle the fuse link following the local regulations.
Step 3
Insert a new fuse link or a placeholder. Depending on the chosen fuse link, use the appropriate spacers. For more information on how to do this, go to Installation of TYTAN® TH1
Step 4
Switch ON.
