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).
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. 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 efficiency.
6.2 Transporting the UPS
Please transport the UPS only in the original packaging. If the UPS requires any type of
transportation, verify that the UPS is disconnected and turned off.
6.3 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. Recommends that the batteries charge for 48
hours after long-term storage.
If batteries were never recharged over 6 months, do not use them. Contact your service
representative.
6.4 Replacing batteries
DO NOT DISCONNECT the batteries while the UPS is in Battery mode.
Consider all warnings, cautions, and notes before replacing batteries.

Servicing should be performed by qualified service personnel with knowledgeable
of batteries and required precautions. Keep unauthorized personnel away from
batteries.
