Powering On Loads

1. 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. Check that the UPS three-phase output voltage and frequency are normal by viewing
AC Output on the MDU. Use a multimeter to check that the valid three-phase output voltage
and frequency are normal.
2. After confirming that the battery strings are properly connected, close the battery string input
circuit breaker. If there are multiple battery strings, close the circuit breaker for each battery
string and then the general circuit breaker between battery strings and the UPS. The No battery
alarm disappears from the MDU.
3. Close the external output switches to supply power to loads.
