input voltage the MB Cap Ultra switches to buffer mode. The green LED 'U OK' goes off. If the
capacitor is almost discharged the LED ' U >' will go off. If the capacitor is no longer in the
position to buffer the U will turn off. The LED 'operation' will light up until the internal voltage
supply breaks down and the LED 'U >' flashes rapidly.

Do connect add-on modules while the MB Cap Ultra 3/24 7S is charging. The
units have to start operation at the same time.

Disassembly
Disassembly is carried out by disconnecting the power supply. The unit will then buffer the load
until the capacitors are discharged. Directly after discharge lighting of the LED 'operation' and
flashing of the LED ' U >' will indicate the voltage-free output.

Never disconnect electrical connections during operation!
Establishing electrical connections during operation must also be avoided!
Maintenance
The unit does not include any components that require maintenance by the user.
The unit should be regularly cleaned.

Assembly
The DC supply has to be mounted to ensure the required
cooling. A minimum distance of 40 mm has to be
maintained between the vent opening and adjacent units.
Installation has to be done to ensure sufficient ventilation.
The ambient temperature specified must not be exceeded.
Max. altitude without derating is 1000 m o. NN. In case
drilling chips can get on respectively inside the unit, the unit
has to be covered during assembly.
(Risk of short circuit!)

On-time period
ON-time depending on load current and ambient
temperature
Only the ON-time is relevant for the consideration
of the charge and discharge cycles. If the buffer
module is charged and operates in standby mode
the unit will not become hot. This corresponds in a
thermal sense to a switched-off unit.
100% ON-time
Continuous charge and discharge mode
permissible.
50% ON-time
Five charge and discharge cycles in
succession permissible.
