To shut down a single UPS: 1. - Page 77 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.
