5.1.4 Powering On Loads
Procedure
Step 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 diagram. Check that the UPS three-phase output voltage and
frequency are normal by choosing System Info > Runn Info > AC Output on the
MDU. Use a multimeter to check that the valid three-phase output voltage and
frequency are normal.
Step 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.
Step 3 Close the UPS downstream output switch to supply power to the loads.

bypass mode; if the bypass is not normal, the UPS supplies no power. Before
shutting down the UPS, ensure that all loads have shut down.
Procedure
Step 1 Shut down the inverter.
