HARGING
During charging, the DC-UPS consumes additional current from the input. See chapter “Input”.
When charging is completed, the “Ready LED” stops flashing and is on solid and the “Ready relay contact” closes.

Initial charging means that no input voltage was applied for several hours or longer and the capacitor is completely discharged by the
internal electronics.
**) Recharging means that the electronics inside the DC-UPS has not completely discharged the capacitor. The values in the table apply when
the input voltage is applied immediately after buffering has stopped.
Note:
At the end of the charging process the active balancing circuit reduces the charging current periodically, which can be
seen as current oscillations on the input current.
