AEG PROTECT A. 500 Power Supply User Manual

The static bypass switch is activated in the event of a mains
failure. The inverter then takes over the voltage supply of the
connected loads, in order to prevent the risk of data loss or
damage to the loads. 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
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.
