If the power module 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 module, or shutdown or fault rectification is performed) and the module can be started, the
module responds to the startup command.
Step 6 After the inverter starts, the UPS works in normal mode. The Bypass mode alarm disappears.
Check that the UPS has transferred to normal mode by viewing the system running status
diagram. During commissioning, check whether the UPS three-phase output voltage and
frequency are normal by viewing AC Output on the screen. Use a multimeter to check
whether the three-phase output voltage and frequency are normal, as shown in Figure 5-13
and Figure 5-14.
