Once you have connected the UPS to a suitable mains
connection, you can start operation using the UPS main
switch. Normally, the UPS operates continuously. The UPS
now supplies the output with voltage, this being signalled by
the symbols mains (LED Line) and inverter (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 bargraph (LED chain on the left hand side of the ON
/ OFF button) show during operation the actual utilization of
the UPS (s. chapter 8.1.1, page 45).
