9 Running and operating the equipment
9.1 Operating the UPS equipment
The operation of this equipment is characterized by various operating modes
and signals.
9.1.1 Operating modes and signals
The most important operating modes of the UPS are as follows:
Charging
operation:
if the mains power is available and the line-side fuse is switched on, the UPS
charging operation is enabled.
-> The batteries are being charged, the UPS has not yet been started.
Display/alarm signal: no display or alarm signal is active in this operating mode
as the UPS has not yet been started.
Startup operation:
if mains power is available, the startup procedure is initiated when the start
button is pressed. The UPS then switches over to bypass operation for approx.
20 seconds. Following this, mains power operation is automatically activated.
If no mains power was available during the startup procedure, the UPS
switches directly to support operation following the startup procedure.
Display/alarm signal: a short progress display characterises the startup
process. No audible alarm signal. The bypass operation phase is shown here
by way of example. The indicators for inverter, bypass, output load of 100% (for
example) and available mains power light up.
