Chapter 2 Battery Installation and Maintenance
2.1 General Recommendations
Take special care when operating the batteries of the Modular UPS system. When all the battery cells
are connected, the battery voltage can exceed 400Vdc, which is potentially lethal
.
Note
The precautions for battery installation, use and maintenance are to be provided by the batteries
manufacturers. The precautions in this section include the key issues that must be considered during the
installation design, which may be adjusted according to the specific local situations.
Battery Room Design
The battery shall be installed and stored in a clean, cool and dry environment.
Do not install the battery in a sealed battery chamber or sealed room. The battery room ventilation
shall at least meet the requirement of EN50272-2001. Otherwise, battery bulging, fire and even
human injury may be caused.
The battery shall be installed far away from the heating source (e.g. transformer). Do not use or store
the battery in the place near the heating source or burn the battery or place it into fire. Otherwise,
battery leakage, bulging, fire or explosion may be caused.
Batteries shall be placed in such a manner that two bare live parts with the potential difference of
more than 150V shall not be contacted at the same time. If it is unavoidable, insulated terminal cover
and insulated cables shall be used for connection.
If external batteries are to be used, the battery circuit breakers (or fuses) must be mounted as close
as possible to the batteries, and the connecting cables should be as short as possible.
Battery Handling
When connecting the battery, follow the precautions for high-voltage operation
Before accepting and using the battery, check the appearance the battery. If the package is
damaged, or the battery terminal is dirty, corroded or rusted or the shell is broken, deformed or has
leakage, replace it with new product. Otherwise, battery capacity reduction, electric leakage or fire
may be caused.
Before operating the battery, remove the finger ring, watch, necklace, bracelet and any other
metal jewelry
Wear rubber gloves.
Eye protection should be worn to prevent injury from accidental electrical arcs.
Only use tools (e.g. wrench) with insulated handles.
The batteries are very heavy. Please handle and lift the battery with proper method to prevent any
human injury or damage to the battery terminal.
Do not decompose, modify or damage the battery. Otherwise, battery short circuit, leakage or even
human injury may be caused.
The battery contains sulfuric acid. In normal operation, all the sulfuric acid is attached to the
separation board and plate in the battery. However, when the battery case is broken, the acid will
