INTRODUCTION
UZ PowerLite L051100-A and L051100-A1 batteries are modules with a capacity of 5.12 kWh and the integrated controller
allows the management of several modules connected in parallel. This manual provides information on how to use the
batteries and on the safety precautions to prevent possible accidents. Therefore, please read this manual carefully and
keep it handy in case of need.
SAFETY PRECAUTIONS
The batteries are designed with extremely high safety standards. Nevertheless, any electrical equipment can be dangerous
if used improperly and, therefore, be the source of possible electric shocks and fires that can cause serious injury, and/or
even death. The following precautions should be followed to the letter.
Failure to comply with the following instructions can result in electric shocks and fires that can cause serious injury,
and/or even death
To connect the batteries, only use the cables supplied.
Do not tamper with the cables. Any damage to the cables may result in electric shock or fire.
Therefore:
1. Do not modify or damage cables
2. Do not place heavy objects on top of the cables and do not subject the cables to traction
3. Do not place the cables near heat sources that can overheat them
5. To disconnect a power or communication cable, pull the plug rather than the cable.
Be very careful when connecting the power and communication cables:
1. If a power cable is connected incorrectly, the contact resistance can cause damage to the batteries and/or lead to
overheating and even fire.
2. Fully insert the cable connectors.
It is forbidden to install the batteries in poorly ventilated rooms, where heat can build up inside the modules and cause a
fire
It is forbidden to install the batteries exposed to sunlight or near heat sources, to avoid thermal deformation, failure or
fire. Take care when installing near windows.
It is forbidden to install the batteries in environments where smoke, steam, high humidity or excessive dust may be
present.
All personal protective equipment (insulating gloves, goggles, etc.) must be worn during installation
It is also mandatory:
1. To prevent water and/or foreign bodies to enter the batteries
2. Water and/or foreign bodies inside the modules can result in electric shock and/or cause fires
3. Should the above two situations occur, immediately switch off the batteries and disconnect all cables.
It is forbidden to open, dismantle or modify the batteries, as this could cause electric shock or fire.
It is forbidden to cover the ventilation openings of the battery modules, to avoid internal overheating or possible fires.
Therefore:
1. Do not install the batteries in poorly ventilated rooms.
2. Remove any dust build-ups from the ventilation openings.
3. Do not install the batteries upside down or on their sides.
4. Do not place the batteries on top of carpets or beds.
5. Do not obstruct the ventilation openings.
Install the batteries in a stable position
1. An unstable installation can cause the batteries to fall, which could result in damage to the batteries and injury to the
users

- 6 -
2. Do not install the batteries upside down or on their side as they could fall, which could result in damage to the batteries
and injury to the users
To avoid damage to the batteries during transport and/or handling, leave them in their original packaging until installation.
Make sure that the mechanical installation follows the instructions in this manual in order to avoid damage or injury. In
case of rack installation, securely fasten the rack to the floor. An entire rack falling could be a dangerous cause of property
damage, personal injury and/or even death.
Do not touch the batteries with wet hands to avoid possible electric shocks.
All wiring must be protected and must not cause mechanical obstacles to people/animals that may transit nearby, becoming
a source of possible fall and/or injury.
If a battery is faulty, switch it off immediately and disconnect all its wiring.
Leaning on, sitting on or stepping on batteries is prohibited, as it could cause personal injury and damage the batteries. It
is also forbidden to place any object on top of the batteries.
When disposing of the batteries and the end of their life, make sure to comply with the regulations of the country of
installation. The product cannot be disposed of as household waste.
In the event of liquid leaking from the batteries, observe the following safety measures:
Do not allow the liquid to come into contact with skin or clothing.
In case of contact with skin or clothing, rinse immediately with plenty of water.
If the liquid comes into contact with the eyes or enters the mouth, rinse immediately with plenty of water and
immediately seek medical attention.
Lastly, contact the support service
PRECAUTIONS FOR USE
Should one of the following situations occur, switch off the batteries and contact customer service.
1. Presence of smoke, strange smell or noise from the batteries
2. Presence of water or foreign objects inside the batteries.
3. Battery falling or damaged casing.
The following is forbidden:
- Removing the batteries.
- Making changes to the product.
- Abnormal charge / discharge, heat generation, gas eruption, or fire.
- Touching the terminals when the batteries are in operation.
- Throwing the product into the fire or expose it to heat and open flames.
- Wetting or immersing the product in any liquid.
- Subjecting the batteries to mechanical stress, shocks and falls.
- Using the batteries for medical purposes.
- Connecting any device that exceeds the operating voltage and current of the batteries
- Disconnecting the cables during battery operation.
- Drilling into the batteries in any way.

INSTALLATION
Power Lite batteries can be installed horizontally or fixed to the wall using the appropriate mounting accessories. In both
cases, the floor or wall must be able to support the full weight of all batteries and other equipment present. For fixing, only
use the original accessories supplied. For the installation instructions for these systems, please refer to the relevant
installation manuals.
The batteries are capable of charging and discharging within the temperature ranges indicated in this manual. When
approaching the limits of the above-mentioned ranges, the batteries can limit the charging or discharging power to
safeguard battery life. Therefore, the batteries should not be operated at temperatures that are too low or too high, such
as in poorly ventilated rooms or exposed to the sun.
The average room temperature should always be between 0 °C and 30 °C
Coils require adequate installation space for wiring and to ensure proper air supply for cooling ventilation. Do not place any
objects in the required free space around the batteries. Do not install any objects on top of the batteries that could restrict
access to the batteries or that could fall on them and damage them. Do not install the batteries upside down
HORIZONTAL INSTALLATION - H100
This type of installation is the most common and requires the H100 accessory. With this system, it is strongly recommended
not to install more than 4 batteries stacked.
