Diagram

Once you have connected the UPS to a suitable mains connection, you can start operation using the UPS main switch (see also "Electrical Start-Up" on page 27). Normally, the UPS operates continuously. The UPS now supplies the output with voltage, this being signalled by the symbols mains (LED Line) and rectifier (LED Inverter) symbols which light up permanently.

This is often referred to as “online” mode. It offers the greatest protection, in particular when there are mains fluctuations and mains failures, because the loads are supplied continuously with voltage with no interruptions in this operating mode.

The LED bar graph (LED chain above the pictogram) show during operation the actual utilization of the UPS (s. chapter 6, page 35).
