NX UPS Single Module And Parallel System 250kVA ~ 800kVA    User Manual 

6.12   Battery Maintenance 

For the battery maintenance and maintenance precautions, refer to IEEE-Std-1188-2005 and the relevant manuals 
provided by the battery manufacturer.   

Note

 

1. Periodically check the screws of the battery terminals for loose connection. If there is any loose screw, tighten it immediately.  
2. Check that all safety devices are present and that their functions are normal. Check that the battery management parameters 
are set correctly.   
3. Measure and record the battery room temperature.   
4. Check the battery terminals for damage and heating. Check the battery enclosure and terminal covers for damage.   

 

6.13   Waste Battery Disposal 

If the battery leaks electrolyte, or is otherwise physically damaged, it should be placed in a container resistant to 
sulphuric acid and disposed of in accordance with local regulations.   

Disused lead-acid storage battery belongs to dangerous waste, and it is a key item for disused battery pollution 
control. The storage, transportation, use and disposal of the battery shall comply with the national and local laws and 
regulations on dangerous waste and disused battery pollution prevention and other standards.   

According to the relevant national regulations, the disused lead-acid storage battery must be recycled and shall not 
be disposed of with other methods. Random discard or any other improper disposal of the disused lead-acid storage 
battery may cause severe environment pollution and the relevant person will be investigated of corresponding legal 
responsibilities.
