9 Initial operation

Ensure that the UPS and its storage medium are correctly installed. The storage medium
can be disconnected and replaced at any time, considering the connecting order (see
page 48/49). Two connections are important: one for data (X4) and one for power (X3).
After connecting a charged battery pack to the UPS, the initial start can take place in two
ways:
1. Start from battery pack into backup operation: By shorting X11 for more than
2 seconds. For this purpose, a push-button can also be used.
or
2. Via connection to upstream power supply: When an input voltage higher
than 11.5 V (UPSI-1208 (D)) respectively 22.5 V (UPSI-2406 (D)) is connected to the
input terminals, the battery pack gets queried and transmits its data. The UPS sets an
appropriate charging end voltage and clears the pack via System Present (X11). Only
then the charger gets enabled and the charging of the battery pack starts. This process
lasts only a few milliseconds.
Use original battery packs from Bicker Elektronik only!
Battery packs from Bicker Elektronik may be used only. These are
appropriate qualified and are equipped with the necessary protective
functions. In addition, the charging characteristic is set by coding.
The applied voltage at the input of the UPS is passed through to the output, reduced by
a current-dependent voltage drop (Vout = Vin - 0.3 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 46, section 8 Dimensioning the power supply).
