Power Capacitor
GB
1 Applications
The power capacitor is used in motor vehicles for sta-
bilizing the 12 V supply voltage for audio power ampli-
fiers and equalizes the load of the voltage in the car in
case of especially powerful, low bass frequencies.
This results in a higher power of the amplifier and a
considerable sound improvement.
2 Safety Notes
The capacitor corresponds to the directive for motor
vehicles and has been tested under the number
e13 021192.
The connection of the capacitor to the 12 V mains
must only be made by qualified, specialized person-
nel. Special care has to be taken. In case of short
circuits there may be dangerously high currents.
The capacitor must be mounted to a mechanically
stable place in the car. It must be skilfully fixed so
that it does not work loose and turn into a dangerous
projectile.
Protect the capacitor against humidity and exces-
sive temperatures (admissible ambient temperature
range -20 °C to +60 °C).
For cleaning only use a dry, soft cloth, by no means
chemicals or water.
If the capacitor is used for purposes other than orig-
inally intended, if it is not connected correctly or not
repaired in an expert way, no guarantee claims for
the capacitor and liability for resulting personal
damage or material damage can be taken over.
If the capacitor is to be put out of operation
definitively, it must be disposed of in a local
recycling plant for a disposal which is not
harmful to the environment.

3 Mounting and Connection
The cables between the capacitor and the power
amplifier should be as short as possible and show a
large cross section*. Lay the cables so that their insu-
lation may not be damaged.
1) Tightly screw the capacitor with the supplied
brackets as close as possible to the power ampli-
fier at a mechanically stable place.
2) The connection is shown in fig. 2. Connect the
negative terminal (4) of the capacitor via a cable to
the ground of the car. To avoid a ground loop,
choose the same place at which also the power
amplifier is connected to ground.
3) Connect a cable with a sufficient cross section* to
the positive pole of the car battery.
Important!
As a protection against short circuits always insert
a fuse* close to the battery (see fig. 2).
For the first charging, connect in any case the
positive cable of the battery and the positive pole
(2) of the capacitor via the supplied incandescent
lamp to prevent damage due to excessive current
peaks.
After charging, if the display value of the digital volt-
meter (5) does not increase further, connect the
positive cable of the battery directly to the positive
terminal (2) of the capacitor. Lay another cable
from the positive terminal of the capacitor to the
supply voltage connection of the power amplifier.
It is recommended to discharge the capacitor after
dismounting to prevent any damage due to acci-
dental short circuit. For this purpose, connect the
supplied incandescent lamp to the two connection
terminals until the lamp is extinguished.

4 Display Elements and Signal Device
1 Buzzer: an alarm sounds if the positive and nega-
tive terminals at the capacitor are mixed up while
connecting. In case of undervoltage (e. g. during
charging) a signal sounds.
5 Digital voltmeter: indicates the applied voltage.
6 Twelve LEDs: flash while the capacitor is charged
or discharged.
7 Fluorescent lamp: ignites from approx. 12 V.
4.1 Fine adjustment of the voltage display
If several capacitors are connected in parallel, each
individual capacitor may indicate a slightly different
voltage due to tolerances. With the trimming potentio-
meter ADJUST (3) adjust the capacitors to the same
voltage display. A precise digital voltmeter should be
used to exactly determine the applied voltage.
