MGE UPS Systems 3.5 to 21 kVA N+1 Power Supply User Manual


 
2.6.3 Unit kVA Rating ID Label
For kVA rating see the inverter ID label. Use the label kVA rating, regardless of the number of inverter modules
installed.
The processor will detect and display the number of modules installed and the number of modules that are “ON”
and operating without fault. MGE is offering the 7, 14, and 21 kVA rating.
2.6.4 On-Line Mode
On-line mode is the mode in which the load is powered by the inverter system, not the utility. It will get clean, tran-
sient free electrical power from the inverter system, which is producing the AC power from a DC power source. In
the event of inverter failure, the static transfer switch will transfer the load to the utility power if available.
2.6.5 Off-Line Mode
Off-line mode is the mode in which the load is powered from the Utility power line (external AC input power). In the
event of a power failure, a static transfer switch will connect the system output to the inverter and activate the invert-
er so as to provide continuous power to the load with no interruptions of power to the load.
