UPSI-1208DPx
F6 Initial operation
The correct installation of the UPS has to be ensured.
The start is accomplished by connecting the upstream power supply: When an input voltage higher
than 11.5 V is connected to the input terminals, the energy storage gets queried and transmits its data. The UPS
sets the corresponding end-of-charge voltage and releases the pack via the system present signal.After that,
the charging of the energy storage starts.
The applied voltage at the input of the UPS is passed through to the output, reduced by a current-dependent
voltage drop (V
= V
OUT
upstream voltage thresholds at the input (UPS function).
It must be ensured that the source supplies enough current to guarantee the charging process (see chapter F4
„Dimensioning the upstream power supply").
Even after disconnecting the upstream source and also no voltage is measurable at the output,
the UPS can be still powered by the energy storage.
