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 77°F (25°C).
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.

When storing the UPS and optional cabinets, the following requirements should be met:
• Verify that the battery circuit breaker is in the OFF position.
• Avoid temperature and humidity extremes. To maximize battery life, the recommended storage
temperature is 59°F (15°C) to 77°F (25°C).
• If you store the UPS for a long period, recharge the batteries every 10 months by applying utility power.
The batteries charge to 80% capacity in approximately 3 hours. However, it is recommended 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 expired and the batteries
were never recharged, do not use the UPS. Contact your service representative.
