The position 0 (=100%) means that the full capacity of UPS can be used. Depending of the connected load
the power supply can be secured for some minutes. The time can be reduced if the connected system shuts
down fast. If the system shuts down fast the restart can be accelerated.
The retention time should last longer than system shutdown time. For secure operation a
time reserve is advised (XPe shutdown time plus 20-30 %)
Note
The retention time can also be set in TwinCAT system manager:
The description can be found in "Settings for UPS module in System Manager".
