Answer: (1) Do not use the air compressor in parallel with equipment with high power consumption to avoid the air compressor electrical protection device from shutting down due to excessive voltage drop or unbalanced three-phase current.
(2) Correctly select the power line diameter that matches the motor power to avoid the danger of burning the power line due to excessive load.
(3) The air compressor must be reliably grounded and is not allowed to be directly connected to the air delivery pipe or cooling water pipe to prevent danger caused by leakage.
(4) If the three-phase current is unbalanced, the difference between the lowest phase current and the highest phase current shall not exceed 5%.
(5) The power cord must be insulated at the line inlet to avoid danger caused by leakage due to friction.
(6) The power supply must be cut off during installation and maintenance, and a warning sign must be hung at the power switch. If the power supply is far away from the work site, the load end of the switch must be removed to ensure personal safety.
