1.2 Short description
The buffered DC power supply of the PowerToStore includes ultra-capacitors as energy storage inside the
housing. During normal operation this capacitor is charged from AC-mains. The connected DC consumers are
supplied as well from AC mains. In case of an interruption of the AC supply, the energy of the ultra-capacitor is
realesed regulated. With a DC/DC converter the load is supplied from the capacitor until it is discharged. The
backup time depends on the state of charge of the capacitor and the discharge current.
The power supply hast he following characteristics:
· Maintenance-free because of long-life ultra-capacitors
· Mikrocontroller based charging and discharging oft he ultra-capacitors
· Control of operation and status of charge with potential-free contacts and LED
· Capacity extension possible with external capacitor extension modules
1.3 Intended use

REFERENCE
·The external energy supply must be connected to a circuit with an own, specially marked
fuse (16A).
·From this fusing up to the supply point of the low voltage side of the electrical mains (house
connection box) it may be fused only one another time.
·It must be excluded, that the circuit tot he external energy supply is interrupted because of
the switch off of other means of production.
REFERENCE
·In case of overload the DC output current is composed of the maximum current of the DC –
DC converter as well as of the current of the AC – DC converter. The output circuit must be
fused externally to avoid an overload!
DANGER
·The unit is prepared for protective system I (protective earthing).
·The operational earth must absolutely be connected. In case of non-observance touchable
parts could carry voltage in case of error. Danger of fatal electric shock.
3.3 Connection
·Prior to connection, the values of the DC supply must be compared with the values on the type plate.
·Connection according to the designations of the connection terminals (see terminal allocation).
·Not used connection screws must be tightened.
·During connection of the load the polarity „+“ and „-“ must be respected.
·The mains voltage must be switched off and must be protected against switch-on by a third party.
·The voltage-free cable must be connected to the designated connection terminal. The mains phase
must be respected. The mains is connected at the terminals „L“, „N“ and PE ( ).
·The operational earth must absolutely be connected.
Dimension the cable cross-section of the supply and outlet lines according to EN 62368-1 Table G.5; see also
the table above.
The status of the external power supply can be transmitted to a subordinate power station. The contacts are
coupled with the corresponding LED displays. The illumination of a LED effects the activation of the corre-
sponding relay.

4.1 Display and messages
Inside the housing there are four LED’s for status display:
(The LED-displays are coupled with corresponding message contacts.)
(The values refer to a standard parameterisation.)
5. Operation
5.1 Mains operation
· After the switch on oft he input voltage Ue the internal energy storage is charged.
· Mains operation is signalised by the LED Ue-OK.
· The charging is signalised by a slow blinking of the LED Uc>. If the capacitor is nearly charged, the
LED Uc> is permanently illuminating, the corresponding relay is activated and Ua is released.
· A charging voltage which is to low is signalized by fast blinking of LED Uc>
5.2 ON-Time
For the examination oft he on-time only the charging and discharging cycles of the capacitors are relevant. If
the back-up module is charged and works in standby mode, no warming of the energy storage occurs.
Display Designation
