① Additionally, the UPS is provided with a timer (time delay) that prevents
that the UPS operation is signaled to the connected PC and initiated
during the first 120 seconds after switching on the UPS. The output
voltage of the UPS is buffered by an integrated accumulator and thus
remains available for the connected PC. After the first 120 seconds the
UPS operation is signaled to the connected PC and is initiated if the
input voltage remains switched off. When a voltage breakdown occurrs,
the set time of the UPS applies (switch position 0 to 3). Thus, it is en‐
sured that a voltage breakdown of the supply voltage does not effect the
initialization phase of the connected PC in any way.
② The time delay of 120 seconds is switched off using the switch positions
4 to 7. Thus, unnecessary waiting times, e.g. during commissioning, are
avoided. After commissioning reset the switch to 0 to 3.
