UPS5000-A-400 kVA
User Manual (50 kVA, PF=0.9)
If the power unit receives a startup command when it cannot be started, the startup command will be
kept for 1 minute. If the startup command is not cleared within 1 minute (for example, other faults occur
on the unit, or you perform shutdown or rectify faults) and the unit can be started, the unit responds to
the startup command.
Step 6 After the inverter is started, the UPS transfers to the inverter power supply mode. You can
check the system running status diagram to confirm that the active inverter supplies power to
the system. During test by engineers, check whether the UPS three-phase output voltage and
frequency are normal by monitoring AC output on the screen, and use a multimeter to check
whether the valid value of three-phase output voltage and frequency are normal.
The three-phase output voltage should be 220 V, 230 V, or 240 V, and the frequency should be 50 Hz or
60 Hz.
