An integrated control panel is equipped with fuses (diodes). Could incorrect wiring of the power supply cables to the distribution cabinet cause damage to the electrical components in the control panel? In fact, this caused the panel electrical components to be damaged and become non-functional.
The control cabinet, although equipped with fuses, can still suffer damage to its electrical components if the power cables are connected incorrectly! One must be cautious.

When will insurance take effect? A fuse is an electrical component installed in a circuit to ensure its safe operation. When a circuit malfunctions or experiences an abnormality, the current level rises continuously. This increased current can damage certain important or valuable components within the circuit, and it may even burn out the circuit or cause a fire. If a fuse is properly installed in the circuit, it will blow and cut off the current when the current rises abnormally to a certain level and at a certain moment, thereby ensuring the safe operation of the circuit. A fuse cuts off the current, thereby ensuring the safe operation of the circuit. But you connected the wires incorrectly; perhaps the voltage is too high, or the phase sequence is reversed... Any of these could cause the insulation of the electrical components to be broken down
Reply to 4# hcwang12345: Does a fuse serve to protect equipment against continuously rising currents? Suddenly, the current has no protective effect?
Reply to 1# security: The fuse (diode) on this circuit board serves to provide protection in case the positive and negative poles of the DC power supply are connected incorrectly. It won’t damage the circuit board. Reasons for circuit board damage: 1. The diode was already broken down. 2. The DC power supply voltage is too high. 3. Connect the AC power supply voltage.
Agree with what was said on the sixth floor. And it is very likely 3: connecting the AC power supply voltage. Because the DC voltage of ordinary equipment is quite stable.
