Protect A supplies voltage until the battery is discharged or your IT
system has been shut down and switched off properly.
The standby time mainly depends on the connected loads. If the
mains power supply is back to normal values, the UPS will
automatically switch back the loads to mains supply. The battery
charger will then recharge the battery.
For safety reasons (as required by German standards, VDE), the
mains input in the unit will be disconnected by a two-pole switch in
the event of a mains failure. Energy backfeed to the mains and
voltage supply to the pins of the mains connector are thus reliably
avoided.
Furthermore, additional measures ensure effective protection for the
data/network interface.
