6.1 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 depends 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.
6.2 Transporting the UPS
NOTE: The internal UPS batteries MUST be disconnected before
transport.
CAUTION: The following procedure should be performed or supervised
by personnel knowledgeable about batteries and the required precaution.
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:
1. Verify that the UPS is off and disconnected from utility power.
2. Place the UPS on a flat, stable surface with the front of the cabinet
facing you.
3. Remove the UPS front cover
