2. To access the fuse, remove the cover of the mounting block. The cover indicates the circuit that the fuse protects. If the circuit fails, first check the fuse. Fuses are installed on blade-type contacts and are removed by hand.
3. A blown fuse can be easily detected by its appearance (see photo). You can also check the voltage at the terminals. The fuse is blown if the voltmeter shows voltage. To replace the fuse, remove the faulty one and insert a new one by pushing it into the socket.
4. The rated current of the new fuse must exactly match the current of the one being replaced. The rated current is indicated on the fuse. It is prohibited to use wire sections instead of a fuse.
5. If the new fuse immediately blows, find the cause and fix it. As a rule, blowing is caused by a short circuit of the wires due to their chafing or aging insulation.
