1.3 Meaning of Symbols
This manual contains the following types of warnings:
Danger! It may cause an electric shock.
Even when the equipment is disconnected from the power grid, the voltage-free
state will have a time lag.
Danger! If the instructions are not observed, death or severe injury may
occur.
Warning! If the instructions are not observed, a loss may occur.
Attention! This symbol represents information on the device use.
Symbols on equipment:
The following types of warning, prohibition, and mandatory symbols are also used on
the equipment.
Attention! The risk of chemical burns
If the battery is damaged or fails, it may lead to electrolyte leakage, which in turn causes the
formation of a small amount of hydrofluoric acid, among other effects. Contact with these liquids
can cause chemical burns.
• Do not subject the battery module to severe impact.
• Do not open, disassemble or mechanically change the battery module.
• In case of contact with an electrolyte, wash the affected area with clean water immediately and
seek medical advice promptly.
Attention! The risk of explosion
Incorrect operation or fire may cause the lithium-ion battery unit to ignite or explode, leading to
serious injury.
• Do not install or operate the battery module in explosive or high-humidity areas.

5
• Store the battery module in a dry place within the temperature range specified in the data
sheet.
• Do not open, drill through or drop the battery cell or module.
• Do not expose the battery cell or module to high temperatures.
• Do not throw the battery cell or module into the fire.
• If there is a fire from the battery, please use the CO2 extinguisher. If there is a fire near the
battery, please use a dry powder extinguisher.
• Do not use defective or damaged battery modules.
Caution! Hot surface
• If a malfunction occurs, the parts will become very hot, and touching them may cause serious
injury.
• If the energy storage system is defective, please shut it down immediately.
• If the fault or defect becomes obvious, special care should be taken when handling the
equipment.
No open fire! It is prohibited to handle open flames and ignition sources near the
energy storage system.
Do not insert any objects into the opening in the housing of the energy storage system!
No objects, such as screwdrivers, may be inserted through openings in the casing of the storage
system.
Wear safety goggles! Wear safety goggles when working on the equipment.
Follow the manual! When working and operating the equipment, the installation
and operation manual provisions must be observed.
