MB Cap Ultra Add-on-module 3/24 1A/21S - 85462
MB Cap Ultra Add-on-module 3/24 1A/21S - 85462
Calculation of buffering time
The energy of the capacitor results from the sum of the individual energies of the MB Cap Ultra
3/24 7s and the connected MB Cap Ultra add-on modules (extension modules).
Buffering time in sec. =
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 MB Cap Ultra 3/24 7s have to be compared with the data of the
MB Cap Ultra add-on modules regarding compliance (see type plate). Connect according to the
indications of the terminals. The terminals Cap. + of the MB Cap Ultra 3/24 7s and of the add-on
modules have to be connected. Then connect the terminals Cap. - of the MB Cap Ultra 3/24 7s and
of the add-on modules. Additional add-on modules can be connected from one module to the next
by looping through from Cap. + and Cap. -.

Set-up
The unit is switched-on by connecting the DC supply to MB Cap Ultra 3/24 7s.
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.
When operating the connected power supply > 24 V lifetime will decrease.
