MB Cap Ultra 10/24 1A/380S - 85467
Lifetime of the
capacitors
The lifetime of the capacitors is
temperature-dependent!
End of lifetime is reached when the
buffering time has fallen to 70% of the
rated buffering time.

Connection
Before installation the data of the DC supply have to be compared with the data on the type plate
and checked for compliance. Connection according to the indications of the terminals (see simplified
diagram and configuration).
In case of overload the DC output current is composed of the max. current of the
buffering module and the current from the supplying DC mains. In order to avoid
overloading of the DC output circuit external protection is required! (For values please
refer to “Technical data”)

Set-up
The unit is switched-on by connecting the DC supply to the terminal 'U '.Input
If the units are used in installations that require overloads for testing (e.g. acc. to
EN60204-1 / VDE0113 Part 1 19.4 Voltage test) the unit has to be separated from the
test set-up before voltage is applied.
(Original text EN60204-1 Components that are not designed for this test voltage have
to be disconnected during the test.)
Check if the connections are correct before first start-up. Establish electrical
connections only when the installation is disconnected from the supply.
Operation
The unit is supplied with energy for charging the capacitors and for supplying the loads (terminal
U ) from the input voltage (Terminal U ). Loads connected in parallel to the input terminal
are not buffered, as they are decoupled via the diode D1 (see “simplified diagram”). Therefore, the
power supply unit can feed additional unbuffered loads. Because of the flow voltage of diode D1
the supply voltage for charging the buffer module should be at least 0.7 V higher than the system
voltage.
After the .U has been switched on the supply voltage is measured and the corresponding
