Ensure that the electrical equipment at the front of the two power lines of the automatic switch-over switch for dual power supplies is disconnected, and confirm that all power outlets in the power switch box are in an open state. Connect the backup switch in the distribution box, then start the backup power supply. Verify that the dual power supply automatic switch-over switch starts the engine properly, and after the engine operates normally, sequentially close the engine's air switch and its internal power control circuit breaker. During the startup and operation of the backup power supply, real-time monitoring of the engine side is required, adjusting current and voltage in response to load changes and handling any anomalies promptly.

After the common power supply system is restored to normal enterprise operations (this is also a rehearsal of the lifestyle for restoring power after routine common power outages), partial preparations should be made to switch back to normal power supply at certain times, in order to promptly and effectively control the circuit switching. In abnormal situations, only professional IT staff on-site can perform system switching operations. When switching, we must avoid excessive force or rapid operation of the switch cut-out. After the dual power supply automatic switching system is tested and completed, the first step is to confirm the shutdown of both power supply sources. After confirming the issue, disconnect the power lines from both the common and backup sides.
