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, depend-
ing 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 con-
necting 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.
