6. UPS maintenance

6.1

Equipment care

For the best preventive maintenance, keep the area around the equipment clean and dust free.
If the atmosphere is very dusty, clean the outside of the system with a vacuum cleaner.
For full battery life, keep the equipment at an ambient temperature of 25 °C (77 °F).
If the UPS requires any type of transportation, verify that the UPS is disconnected and turned off .
The batteries are rated for a 3-5 year service life. The length of service life varies, depending on the frequency
of usage and ambient temperature (life divided by 2 each 10 °C above 25 °C).
Batteries used beyond expected service life will often have severely reduced runtimes. Replace batteries at
least every 4 years to keep units running at peak effi ciency.
Batteries runtime will be reduced at low temperature (below 10 °C).
6.2

Storing the equipment

If you store the equipment for a long period, recharge the battery every 6 months by connecting the UPS to
utility power. The internal batteries charge to 90% capacity in less than 3 hours. However, Eaton recommends
that the batteries charge for 48 hours after long-term storage.
Check the battery recharge date on the shipping carton label.
If the date has passed and the batteries were never recharged, do not use them. Contact your service
representative.
6.3

When to replace batteries

Eaton UPS batteries have an expected life span of 3-5 years. After 4 years of operation, the UPS will provide
a battery replacement notifi cation reminding you that your batteries are nearing the end of their useful life.
You should take proactive steps to ensure you replace your batteries for optimal operation and reliability.
Contact your service representative to order new batteries.
Battery recommended replacement date can be accessed through the LCD (Measurements > Battery).
