UPS operation is signaled to the connected PC. As soon as the UPS time "t "
has expired, the output voltage on the VAU 01.1U is switched off.

Timing
If the input voltage on the UPS VAU 01.1U drops, the output voltage is buf‐
fered via the battery and signaled to the connected PC. After the UPS time "t"
has expired, the output voltage on the VAU 01.1U is switched off.

Timing
If after initiated UPS operation, the supply voltage is switched on again, the
UPS operation is not interrupted. In this case, after the set UPS time has ex‐
pired the UPS output voltage of the VAU 01.1U ("24V Out") is switched off
and is switched on again after approx. 6 seconds.
