E5 Initial operation
Ensure that the UPS is correctly installed.
Via connection to upstream power supply:
When an input voltage higher than 22.5 V (UPSI-2406DP1 /
UPSI-2406DP2) is connected to the input terminals, the energy storage medium gets queried and transmits its
data. Only then the charger gets enabled and the charging of the battery pack starts. This process lasts only a
few milliseconds.
The applied voltage at the input of the UPS is passed through to the output, reduced by a current-dependent
voltage drop (Vout = Vin - 0.5 V at maximum current). The device charges the energy storage and monitors the
upstream voltage thresholds at the input (UPS function).
It must be ensured that the source supplies enough current to guarantee the charging process (see also page
20, section E4 „Dimensioning the upstream power supply“).
When using the Windows® Software to shut down the system, make sure that the following settings
are done:
Control Panel >> System and Security >> Power Options
Choose what the power buttons do
>> When I press the power button: Shut down
