1.3 Battery application area
1.3.1 Appropriate use
The AXIstorage Li SH is a battery system. It serves asan energy storage device withinanelectricity
storage system forprivate households and small businesses. It enables you to temporarily store self -
produced electricity, e.g. from photovoltaic - or CHP (cogeneration of heatand power) plants. The
electricity can later be used when needed.
In a battery system, 3 to 6 Energypack can be connected to one anotherin series.
AxitecEnergy GmbH& Co.KGis not liable forpersonal injury and/or material damage due to
improperuse of the energystorage system.
The battery system is a self-contained unit which is only functional after properinstallation with an
approved inverter.
A maximum of 6 Energypack can be connected serially in the AXIstorageLi SHbattery system.
In orderto 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 componentsare 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 systemwith other Energypack.
Do not use the battery systemoutside 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.

V2002 1 3 E N S e i t e 8 | 27
1.4 Main hazards
You can expect zero danger from the battery under normal conditions. The battery corresponds to
the state of the art inscience andtechnology. However,it is obviously impossible to completely
exclude risks if the battery ismisused orin the event of technical failure. In case of lithium-ion
batteries, these generally includefire, explosion, chemical burns and electricshock.
The product-specificrisk of hazards is elevated by
Water (e.g. flooding)
Heat exposure (>70 °C)
Failure ormalfunction of the control system due to electromagneticradiation
Touching live components may cause an electric shock when Energypack 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, ordeath.
Overload, short circuit or arcing can cause a lithium-ion firewith thermal runaway. People can be hit
by electrolyteor 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 AxitecEnergy orthe AxitecEnergy itselfmay work with the
battery system.
Do not leave the children unattendedorallow them tobe nearthe battery system.
High currents have effects on medical implants.
People with implants must be careful not to be in the directvicinity of the battery during
operation.

1.6 Personal protective equipment (PPE)
Use foot protection and hand protection during assembly.
1.7 Emergency instructions
1.7.1 Measures in case of fire
Do not inhale smoke and vapors.
Reporta lithium-ion fire tothe 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 immediatelyorgo 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 consulta doctor.
1.7.3 Measures after electrical shock
Ensure that the system is at zero voltage.
For unconscious patients: Ensure respiration and cardiovascularfunction. If necessary,
initiate cardiopulmonary resuscitation immediately.
For responsive patients: Cool burn injuries and coverthem by dressing the wound.

3Commissioning
3.1 Safety Instructions
The installation may only be carried out by qualified electricians according toIEC 60204
(InternationalElectrotechnical Commission)-1.
The housing including electronics weighs 41kg. One Energypack weighs 22 kg. Heavy lifting can cause
a disturbance of the musculoskeletal system.
Lifting the AXIstorage Li SH cover (11 kg) andbase (30 kg) separately
If and as necessary, donot lift the AXIstorage Li SHbase alone or be sure to use
transport aids.
Risk of crushing and abrasions when lifting and inserting the Energypack.
Use foot and hand protection.
3.2 Installation
3.2.1 Transport
If the installation site is difficult to access, it is recommended that the base and the hood of the
system housing be carried to the installation siteseparately:
1. Open the packaging of the AXIstorage Li SH system housing.
2. Unscrew 2 screws (hexagon socket, SW4) at the front of the bottom of the system
housing
3. Remove the hood from the system housingbase.
4. Carry the hood and base to the installation site individually.
The Energypack should be transported to the installation site in their original packaging.
3.2.2 Choice of intallation site
The battery system can be mounted uprighton the floor.
It is recommended thatthe inverterbe installedon the flooragainst a wall, where itcan be mounted
centrally above the battery system. The invertershouldbe mounted at least 20 cm above the battery
system. Ata distance of up to 30 cm, the cables already attached to the AXIstorage Li SH can be used.
Leave space of at least 30 cm free to the left and right of the battery system to get to the DC
disconnect switch to ensure sufficient air circulation.
To prevent the battery system from tipping over, it can be secured to the installation wall with two
screws (not supplied). Two fixing points are provided in the system housing for this purpose .
Four fixing points are providedin the systemhousing forwall mounting. Since the battery systemcan
weigh up to 173 kg, it must be checked in advance whether the wall and fastening material are
suitable to support the loadin the long term.

V2002 1 3 E N S e i t e 15 | 27
3.2.3 Mounting
The installation location forthe battery system and the inverterhave been determined.
Recommended mounting:
1. Install the wall bracketof the inverter.
2. Hook the inverterinto its bracket.
3. Unscrew the cover of the connectionarea.
4. If not already done, remove the coverfromthe
battery system housing:
Unscrew 2 screws (hexagon socket, SW4) on the
front underside.
Remove the coverfromthe base.
Position the base of the battery housing atthe intended installation location (and screw it on if
necessary).
