1.3 Battery application area
1.3.1 Appropriate use
The AXIstorage Li SH is a battery system. It serves as an energy storage device within an electricity
storage system for private households and small businesses. It enables you to temporarily store self-
produced electricity, e.g. from photovoltaic - or CHP (cogeneration of heat and power) plants. The
electricity can later be used when needed.
In a battery system, 3 to 6 Energypacks can be connected to one another in series.
Axitec Energy GmbH & Co.KG is not liable for personal injury and/or material damage due to improper
use of the energy storage system.
The battery system is a self-contained unit which is only functional after proper installation with an
approved inverter.
A maximum of 6 Energypacks can be connected serially in the AXIstorage Li SH battery system.
In order to avoid dangers such as water pipe bursting, the Energypack must be stored at least 15 cm
above the floor. Proper installation of the AXIstorage Li SH fire pump ensures that the active electrical
components are at least 15 cm above the floor.
The AXIstorage Li SH battery system may:
only be used with Energypack.
only be used with compatible inverters.
only be used in closed rooms.
only be used in an undamaged condition and in accordance with the operating
instructions.
Any other usage is not intended.
1.3.2 Perilous misuse
Do not use the battery system with other Energypacks.
Do not use the battery system outside its performance limits.
Do not install the battery system in rooms at risk of flooding.
Do not connect the battery system to devices not approved for this purpose.
Do not open Energypack. The Energypack may only be opened by trained
service personnel.

V 2 1 0 1 0 1 EN S e i t e 8 | 28
1.4 Main hazards
You can expect zero danger from the battery under normal conditions. The battery corresponds to the
state of the art in science and technology. However, it is obviously impossible to completely exclude
risks if the battery is misused or in the event of technical failure. In case of lithium-ion batteries, these
generally include fire, explosion, chemical burns and electric shock.
The product-specific risk of hazards is elevated by
Water (e.g. flooding)
Heat exposure (> 70 °C)
Failure or malfunction of the control system due to electromagnetic radiation
Touching live components may cause an electric shock when Energypacks are connected in series. The
electric shock can have thermal or muscle paralyzing effects. The latter can lead to ventricular
fibrillation, cardiac arrest or respiratory paralysis, or death.
Overload, short circuit or arcing can cause a lithium-ion fire with thermal runaway. People can be hit by
electrolyte or molten material. In the event of fire, there is a risk of suffocation due to lack of oxygen
and a risk of poisoning due to toxic fumes.
1.5 Qualification of the users
Only the electricians qualified by the Axitec Energy or the Axitec Energy itself may work with the battery
system.
Do not leave the children unattended or allow them to be near the battery system.
High currents have effects on medical implants.
People with implants must be careful not to be in the direct vicinity of the
battery during operation.

1.7 Emergency instructions
1.7.1 Measures in case of fire
Do not inhale smoke and vapors.
Report a lithium-ion fire to the fire department.
If possible: Close the doors.
If possible: Cool the Energypack with water. Avoid contact with the extinguishing water!
1.7.2 Measures after gases or liquids have escaped
Escaping gases can cause respiratory problems.
Ventilate immediately or go out into the fresh air, in more extreme cases, call a
doctor immediately.
Skin contact may cause skin irritation.
Wash skin thoroughly with soap and water.
Eye contact may cause irritation to the eyes.
Immediately rinse eyes thoroughly with water for 15 minutes, then consult a
doctor.
1.7.3 Measures after electrical shock
Ensure that the system is at zero voltage.
For unconscious patients: Ensure respiration and cardiovascular function. If
necessary, initiate cardiopulmonary resuscitation immediately.
For responsive patients: Cool burn injuries and cover them by dressing the
wound.
