5) Turn on the remaining UPS according to the previous section.
Warning: (Only for the parallel system)
● Before turning on the parallel system to activate inverter, make sure that all unit’s maintenance switch at
the same position.
● When parallel system is turned on, please do not operate the maintenance switch of any unit.
● Please Do NOT enable the ECO mode in parallel system.
