PRECAUTIONS
Important safety instructions. Read carefully and keep for future reference!
Persons not holding written authorisation from manufacturer are not permitted to proceed
with any change, modication or repairs that may be required. Only original parts may be used
for authorised modications or replacements.
The Stromtank is only designed for indoor use and must under no circumstances be subjected
to rain, snow or other humid or dusty conditions. The maximum specications of the device
shown on the type plate must be adhered to.
The weight of the Stromtank can be up to 265 Ibs /125 kg depending
upon the model. Use an appropriate lifting method as well as help from a
third party when installing the equipment.
When the Stromtank is running, it generates voltage that can be potenti-
ally lethal. Work on or close to the installation must only be carried out by
thoroughly trained and qualied personnel. Do not attempt to carry out
on-going maintenance of this product yourself. There are NO USER SER-
VICEABLE PARTS INSIDE the unit. Do not open the chassis or remove any
of its screws. In case of any service needs contact your Stromtank dealer.
When working on the electrical installation, it is important to be certain
that the source of DC voltage coming from the battery as well as the sour-
ce of AC voltage coming from a generator or electric circuit have been
disconnected from the electrical installation.
Even when the Stromtank has been disconnected from the supply sour-
ces (AC and DC), a dangerous voltage may remain at the outputs. To eli-
minate this risk you must switch the Stromtank OFF using the ON/OFF
button. After 10 seconds the electronics are discharged and interventi-
on may take place without any danger. All elements connected to the
Stromtank must comply with the applicable laws and regulations.

INSTALLATION / OPERATION
Before you start with the installation take care that no audio parts are connected with the
Stromtank and the unit is not connected with the electric circuit.
To install the Stromtank and connect it with your audio equipment please follow the steps in
order.
1. Make sure that the position of the main switch at the rear is in OFF position.
2. Connect the AC input with a power cord to the next available grid outlet.
ATTENTION: Never connect Stromtank’s AC input with its AC outlets. This will cause
damage to the unit!
3. Insert the supplied key into the key switch, turn it into a horizontal position and remove
the key from the switch.
4. Push the main switch at the rear in ON position. The green LED above must light up now.
After a few seconds the ampere meter at the front is illuminated by a blue light.
5. Plug your audio AC cords into the AC outlets. It is important to make certain that all audio
units are in OFF position. For best sound results we recommend a cable length of AC-out
power connection between STROMTANK and hi equipment of max. 5 meters.
6. Switch on the fuse switch next to the AC outlets.
7. Turn on your connected audio equipment. ATTENTION: One after the other!
8. To select pure power OFF-grid mode and enjoy best music with stable AC amplitude, pure
sinewave and crystal controlled frequency push the left button at the front and the light of
the meter will change to a green illumination. Or go to grid mode (switch left button again)
for charging and on-grid music listening.
Turn on your audio system. To hear the best quality of your audio components it is recom-
mended to start with OFF-grid mode. This allows Stromtank to warm-up and shakedown the
system.
ATTENTION: Stromtank must always be connected with the ground of the power cord.

DISPLAY OPERATION
REMOTE CONTROL
The LED bargraph at the front of Stromtank indicates the state of charging in 10 steps from 10 %
up to 100 %. When all 10 indicators are illuminated the unit is fully charged (100 %). If only one
indicator is shown the unit is nearly empty (state of charging: 10 %).
If Stromtank operates in battery-mode (green) and reaches a rest capacity of 10 % it automati-
cally switches back to blue mode (grid) charging the batteries. In an area up to 20% battery
capacity it is not possible to switch the unit manual back to battery-mode (green). If you are
not doing any activity the charging process goes on until the unit is fully charged and stops
automatically when the capacity reaches 100%.
This “security function” ensures that the battery cannot totally be discharged, e.g. if you forget
to switch the unit to charging-mode after a music session.
ATTENTION: Do not forget to switch back to ON-grid mode for charging the batteries.
If the you see a red lighting LED at the front check that the AC-in power cord of Stromtank
is connected properly to the electric circuit. The red LED also indicates that the AC-in fuse is
blown.

ADVANCED FEATURES
Stromtank - Inverter
The Stromtank is equipped with a high-performance inverter, which supplies a perfect and
very precise sine wave. Any unit designed for the 230V –50 Hz / 115V – 60Hz electric circuit can
be connected to it without any problem, up to the rated power out of the Stromtank. The
Stromtank is protected against overloads and short-circuits.
Thanks to the largely over-dimensioned performance level, loads up to three times higher
than the Stromtank’s rated power can be faultlessly supplied for short periods (3 sec) of use,
thus allowing the load to be started up without any problem.
Automatic Load Detection (Load Search)
In order to save battery energy, the Stromtank stops and automatically goes into load search
mode when the detected load is lower than the sensitivity (2,5W). It automatically goes back
into operation when a power consumer greater than this value demands it.
In load search mode (standby), the system will thus consume minimal power from the battery.
Hybride Mode
In this mode the current taken on AC-Input is a sinusoid in phase with voltage. That means only
active power is taken from the generator. The Stromtank compensates harmonics and reactive
current from the source.
This function also avoids fast speed change on the generator due to loads jump.
Battery Undervoltage Protection
Stromtank switches o the AC-output group automatically in case the batteries reach under-
voltage level. Before it will be switch o there will be an acoustic alarm signal for approx. 1 mi-
nute. If the red LED at the front is lighting check if Stromtank is connected by AC-in power cord
to the electric circuit. When the red lighting of the LED at the front disappears the charging
mode started (front meter shows charge current). If the connection works and the red LED is
still on check the AC-input fuse.

MAINTENANCE
STORAGE
The Stromtank requires no user maintenance other than to keep it clean. Like a piece of furni-
ture the Stromtank has a ne, highly polished nish that can be easily damaged. Do not rub or
polish the nish and do not allow objects to come in contact with it.
To clean the Stromtank rst unplug the unit from the electric circuit. To wipe o ngerprints
and other grease spots spray a small amount of mild detergent dissolved in water onto the
supplied microber cloth and gently wipe the surface with the close.
Caution! The cloth must never be dripping wet! If water or other uids enter the cabinet, you
risk damaging the unit. Do not spray any liquid directly onto the Stromtank.
Never use scouring pads, steel wool, scouring powders or harsh chemical agents, alcohol, thin-
ners, benzine, insecticide or other volatile substances, as these can permanently scratch and
destroy the surface.
If you need to transport or ship the Stromtank, make sure to use the original packing material.
Allow the unit to cool down for at least one hour before you wrap or package it.
The equipment must be stored in a dry environment at an ambient temperature of between
10 °C (50 °F) and 45 °C (113 °F.)
