F6 Initial operation
The correct installation of the UPS has to be ensured. After that, the start can take place in two ways:
1. By connecting the supply voltage (standard):
If a voltage more than 22.8 V is connected to the input terminals, the energy storage is queried and trans-
mits its data. The UPS sets the appropriate end-of-charge voltage and releases the pack via system
present. After that, the charging of the energy storage starts.
OR
2. Starting the battery from the energy storage into battery mode (alternative):
By pressing the BS button for more than 2 seconds (max. 5 s). See also chapter F12 „Battery start“.
The applied voltage at the input of the UPS is passed through to the output, reduced by a current-dependent
voltage drop (V
OUT
= V
IN
- 0.6 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 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.
