Note:
• The “Permitted Maximum Power” does not mean that the UPS will be overloaded if this power value is
exceeded. For example, when selecting the 2+2 configuration, the rated UPS apparent power is 100kVA
and active power is 100kW, therefore, if load exceeds the permitted maximum power 50kW (permitted
maximumpower),theUPSwillnotbeoverloadedandonlytheN+X(X=2)structurewillbechanged.
• The “permitted maximum power”indicates the three-phase power, so the permitted maximum power of
single-phase needs to be divided by three.
