6.1 Operating modes
Protect D LCD UPS can work in one of these operating modes:
- Operation with existing mains
- Operation with faulty mains
- Operation with faulty inverter
- Manual bypass
6.1.1 Normal operation
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.
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.
6.1.2 Battery operation / autonomy operation
The mains is not within the required tolerance range or has failed. In this
case power is supplied to the inverter from the charged battery without
interruption. The power supply to the loads is therefore also ensured in
the event of a mains failure.
