UPS and Battery Care
For the best preventive maintenance, keep the area around the UPS
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 UPS at an ambient temperature of
25°C (77°F).
NOTE
If the UPS requires any type of transportation, verify that the UPS is unplugged and
turned off and then disconnect the UPS internal battery connector using the steps in
“Connecting the UPS Internal Battery” on page 16 in reverse order.
NOTE
The batteries in the UPS are rated for a 3–5 year service life. The length of service
life varies, depending on the frequency of usage and ambient temperature. Batteries used
beyond expected service life will often have severely reduced runtimes. Replace batteries at
least every 5 years to keep units running at peak efficiency.
Storing the UPS and Batteries
If you store the UPS for a long period, recharge the batteries every
12 months by plugging the UPS into a power outlet. The batteries
charge to 90% capacity in approximately 3 hours. However, it is
recommended that the batteries charge for 24 hours after long-term
storage.
Check the battery recharge date on the shipping carton label. If the date
has expired and the batteries were never recharged, do not use the
UPS. Contact your service representative.
