After the Delta or non-Delta external maintenance bypass cabinet's manual bypass breaker
or switch (Q3) is turned on, the UPS will be switched to manual bypass mode, and the
screen above will appear. Before maintenance personnel perform maintenance, the UPS
must be switched to this mode and it must be ensured that all input power and battery power
are disconnected. After power disconnection, the LCD will be off. If there is any sudden
malfunction in the bypass, the loads will lose power and become unprotected. Please refer to
6.2.4 Manual Bypass Mode Start-up Procedures.
