System safety and environmental precautions
Product warranty becomes invalid if following precautions are not followed during handling, storage,
installation, commissioning and operation of Pixii energy storage systems.
General precautions
Althoughthissystem incorporatesprotectivecircuits andothersecurity features,itmay still bedestroyed,
damaged, work poorly or shorten its lifetime if exposed to improper handling during transportation,
installation or operation. Always handle the system with care, use proper lifting techniques, do not roll,
climb or drill holes in the cabinet or enclosure.
Opening the equipment may cause serious injury even when theAC power is disconnected. Dangerous
voltage may be present inside, as system can be still running from batteries or capacitors may still be
charged.
Environmental precautions
Some devices can reach high temperatures during normal operation. It is very important to ensure that
airow through equipment is not blocked, lters are in good condition and fans can rotate freely. If other
equipment is installed in close proximity, secure that inlets and outlets are not blocked.
Electronic devices installed in the energy storage system are designed for indoor environment with
pollution degree 2. When installed in an outdoor enclosure (open or closed loop heat management
system), it is important to ensure, that the enclosure is closed and sealed during normal operation,
to avoid external air with increased level of humidity and dust from entering. In addition, in open loop
systems, lters maintenance must be properly planned. In case of indoor systems, operating environment
must be of pollution degree 2, without increased level of dust and humidity.
Installer is responsible to protect system against current surges, over-voltages, etc. caused by lightning,
electrostatic discharges, etc. To avoid system damage, it is mandatory to always install proper SPDs.
Installation precautions
Read carefully user documentation before installation and using this equipment. Follow all commands,
always use recommended tools and torque values as described. Commissioning and conguration of
equipment should be done only by Pixii personnel or by other authorized and qualied persons.
For safety reason, before you start installation, ensure all external power sources are disconnected, as
well as internal battery and load fuses/breakers. To avoid injuries caused by high leakage/touch current
you must always start installation by connecting earthing wire (PE), before you connect other AC input
wires (phases, neutral).
If system contains batteries, they represent major energy hazard. To avoid short circuit on batteries,
do not operate with full metallic tools close to battery poles. Be careful also about other objects (rings,
watches, necklaces, etc.).
All Pixii devices are certied according to international safety, environmental and EMC standards. If
any other devices will be installed inside this product, it might inuence parameters and violate original
approvals. Installer is responsible that during installation environmental properties of this device are not
impaired and installation is according to local regulations.

Response to emergency situations
While the battery module comprises multiple battery cells that are designed to prevent hazards resulting
from failures, Pixii can not guarantee their absolute safety.
In the event that hazardous quantities of electrolyte are released, or in case of smoke, or re, leave the
battery room and contact the re brigade.
Leaking batteries
If the battery module leaks electrolyte, avoid contact with the leaking liquid or gas. Electrolyte is corrosive
and contact may cause skin irritation and chemical burns. If one is exposed to the leaked substance, do
these actions:
Inhalation:
Evacuate the contaminated area, and seek medical attention immediately.
Eye contact:
Rinse eyes with owing water for 15 minutes, and seek medical attention immediately.
Skin contact:
Wash the a󰀨ected area thoroughly with soap and water, and seek medical attention immediately.
Ingestion:
Induce vomiting, and seek medical attention immediately
Rinse mouth and wash around the mouth with water.
Burns: If burns are caused, treat them accordingly. Likewise, immediate medical attention shall be
obtained.
Fire
In case of a re, make sure that an ABC or carbon dioxide extinguisher is nearby. If a re breaks out
where the battery module is installed, do these actions:
1. Extinguish the re before the battery module catches re.
2. If the battery module has caught re, do not try to extinguish the re. Evacuate people immediately.
Wet batteries
If the battery module is wet or submerged in water, do not try to access it. Contact Pixii or your distributor
for technical assistance.
Damaged batteries
Damaged batteries are dangerous and must be handled with extreme caution. They are not t for use
and may pose a danger to people or property. If the battery module seems to be damaged, pack it in its
original container, and then return it to Pixii or your distributor.
!!! Caution !!!
Damaged batteries may leak electrolyte or produce ammable gas. If you suspect such damage,
immediately contact Pixii for advice and information.
!!! Warning !!!
The battery module may catch re when heated above 150°C.
If the battery catches re, it will produce noxious and poisonous gases. Do not approach.

Introduction
1�3 Thermal management system (TMS)
Cabinet thermal management system provides appropriate thermal conditions inside the cabinet.
Solution is integrated on the cabinet door with controlled air ow inside the cabinet.
There are two options – Fan Filter or Hybrid Air Condition & HEX solution.
1�3�1 Fan lter
Fan lter TMS using free cooling principle which is open loop system. Outside cold air is pulled into the
cabinet through the inlet lter and hot air is pushed out through the outlet lter. Inlet lter with two fans is
installed at the bottom and outlet lter at the top of the door. This principle provides overpressure in the
cabinet. Input and output air is ltered from dust or other particles. The lter must be changed when the
cabinet is no longer able to maintain the required temperature level. Filter change interval depends on
di󰀨erent factors as pollution, heat dissipation, thermal requirements or solar load.
The advantage of free cooling is large amount of exchanged air which is giving very high cooling
performance at low power consumption. The temperature inside the cabinet is always higher than
ambient (outside) temperature. With moderate ambient temperatures or low power dissipation the fans
will be running at low speed.As the ambient temperature or internal power dissipation increases the fan
speed will increase.
Fan lter solution also provides additional air recuperation mounted inside the door, helping to spread
the air evenly in the cabinet. It secures similar temperature around the batteries.
Cabinet is equipped with 2x 500W AC powered heaters for lower temperature conditions securing
adequate battery temperature.
