(1. equipment failure caused by incorrect power supply. There are several possible reasons for incorrect power supply: incorrect power supply line or voltage
Insufficient power (or insufficient line diameter of a certain power supply line, excessive step-down, etc.), short circuit, open circuit and instantaneous over-voltage of the transmission line of the power supply system
Pressure, etc. In particular, equipment damage caused by power supply error or instantaneous overvoltage occurs frequently. Therefore, during system commissioning, before power supply,
We must check and check carefully and strictly, and never take it lightly.)
