(1) Before installation, it should be checkedSiemensWhether the additional voltage of the fuse is greater than or equal to the additional voltage of the line. Whether the additional breaking capacity of the fuse is greater than the expected short-circuit current in the line, and whether the additional current of the melt is less than or equal to the additional current of the fuse support.

(2) Siemens fuses should generally be straight, and the device should ensure that the contact between the melt and the contact knife and the contact knife and the tool holder is outstanding, and can avoid the arc flying to the adjacent live part.

(3) Care should be taken not to allow the melt to be mechanically damaged when installing. Prevents malfunction due to the reduction of the melt cross-section.

(4) When installing, attention should be paid to making the temperature of the medium around the fuse consistent as much as possible with the temperature of the medium around the target to be maintained, so as to avoid errors in maintenance characteristics.

(5) The device must be reliable to avoid a phase with poor touch and a situation equivalent to a phase break, resulting in the electric Hu being burned due to phase failure.

(6) When installing a fuse with a fuse indicator, the indicator should be installed in a position that is convenient for observation. (7) The connecting wires at both ends of the fuse should be firmly connected. The screws should be tightened.

（8）SiemensThe device orientation of the fuse should be convenient for replacing the melt.

(9) When installing a spiral fuse, the lower terminal block of the fuse
