5. Battery maintenance
●
This series UPS only requires minimal maintenance. The battery used for standard models is valve regulated sealed lead-acid maintenance
free battery. These models require minimal repairs. The only requirement is to charge the UPS regularly in order to maximize the expected
life of the battery. When being connected to the utility power, whether the UPS is turned on or not, the UPS keeps charging the batteries
and also offers the protective function of overcharging and over discharging.
●
The UPS should be charged once every 4 to 6 months if it has not been used for a long time. In the regions of hot climates, the battery
should be charged and discharged every 2 months. The standard charging time should be at least 12 hours.
●
Under normal conditions, the battery life lasts 3 to 5 years. In case if the battery is found not in good condition, earlier replacement should
be made. Battery replace event should be performed by qualified personnel.
●
Replace batteries with the same number and same type of batteries.
●
Keep the ambient temperature between 15
℃
and 25
℃
.
●
Do not replace the battery individually. All the batteries should be replaced at the same time following the instructions of the battery
supplier.
●
Normally, the batteries should be charged and discharged once every 4 to 6 months. Charging should begin after the UPS shuts down
automatically in the course of discharging, the standard charging time for the standard UPS should be at least 12 hours. Discharge the
battery with the load more than 50%.
6. Notes for battery disposal and battery replacement
1) Before disposing batteries, remove conductive articles such as necklace, wrist watches and rings.
2) If it is necessary to replace any connection cables, please purchase the original materials from the authorized distributors or service
centers, so as to avoid overheat or spark resulting in fire due to insufficient capacity.
3) Do not dispose of batteries or battery packs in a fire, they may explode.
4) Do not open or mutilate batteries, released electrolyte is highly poisonous and harmful to the skin and eyes.
5) Do not short the positive and negative electrodes of the battery, otherwise, it may result in electric shock or fire.
6) Make sure that there is no voltage before touching the batteries. The battery circuit is not isolated from the input potential circuit. There
may be hazardous voltage between the battery terminals and the ground.
7) Even though the input breaker is disconnected, the components inside the UPS are still connected with the batteries, and there are
potential hazardous voltages. Therefore, before any maintenance and repairs work is carried out, switch off the breaker of the battery
pack or disconnect the jumper wire of connecting between the batteries.
8) Batteries contain hazardous voltage and current. Battery maintenance such as the battery replacement must be carried out by qualified
personnel who are knowledgeable about batteries. No other persons should handle the batteries.
