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:
S
Verify that the battery circuit breaker is in the OFF position.
S
Avoid temperature and humidity extremes. To maximize battery life, the
recommended storage temperature is 59°F (15°C) to 77°F (25°C).
S
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.
S
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.
