UPS and Battery Care

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 25°C (77°F).

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.

Transporting the UPS

NOTE: The internal UPS batteries MUST be disconnected before transportation.

CAUTION: The following procedure should be performed or supervised by personnel knowledgeable about batteries and the required precautions. Keep unauthorized personnel away from batteries.

If the UPS requires any type of transportation, the batteries must be disconnected (but not removed) before the unit is transported:

1Verify that the UPS is off and unplugged.

2Place the UPS on a flat, stable surface with the front of the cabinet facing you.
