This menu allows you to perform active/standby switchover on the UPS. When you need to
maintain an ECM and it is working, perform active/standby switchover on the ECM. After
switchover, ensure that the ECM stops working (the yellow or red indicator is on, or the green
indicator is blinking) before you maintain it.

Only professional personnel are allowed to use this function.
Perform active/standby switchover (takes about 30 seconds) only after the ECM is inserted,
other configurations are completed, and the ECM starts running properly.
