7.1.3 Powering On Loads

Procedure
Step 1 After the inverter starts, the UPS works in normal mode. The Bypass mode alarm
on the LCD disappears. Check that the UPS works in normal mode on the System
Status screen of the LCD.
Step 2 Choose System Info > Runn. Info > AC Output on the LCD and check that the
UPS three-phase output voltage and frequency are normal. Use a multimeter to
check that the valid three-phase output voltage and frequency are normal.
Step 3 After confirming that the battery string is properly connected, switch on the
battery string input circuit breaker. If there are multiple battery strings, switch on
the circuit breaker for each battery string and then the general circuit breaker
between the battery strings and the UPS. The No battery alarm on the LCD
disappears.
Step 4 Turn on the downstream output switch to supply power to loads.

If the power module receives a startup command when it cannot be started, the startup
command will be retained for 1 minute. Within 1 minute, if there is no situation (for
example, the power module encounters other faults, executes a shutdown command, or a
fault is rectified) that requires the startup command to be cleared and the power module
becomes able to start, then the power module responds to the startup command.
