F6 Initial operation
The correct installation of UPS and energy storage has to be ensured. The energy storage can be unplugged
and exchanged at any time in compliance with the connecting order (see chapter F5 „Connecting diagram“).
There are three connections to consider: a data connection to the battery (BAT DATA), a power supply to the
battery (BAT PWR) and the input / output to the UPS.
After that 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.
Only energy storages by Bicker Elektronik may be used. These are appropriately qualified and have the neces-
sary protective functions. In addition, the charging methods are set using internal codes and settings.
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.
