Before performing maintenance, review Chapter 3, "Safety Overview,"
and be familiar with all equipment safety features and precautions.
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 longest 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.
NOTE The ultracapacitor module has an indefinite life. It requires no special
procedures other than the temperatures stated for the batteries.
