7. UPS maintenance
7.1 Equipment care
For the best preventive maintenance keep the area around the equipment clean
and free from dust. If the atmosphere is very dusty, clean the outside of the
system with a vacuum cleaner.
For maximum battery life keep the equipment at an ambient temperature of 25°C
(77°F).
The batteries are rated for a 3-5 year service life. The 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 4 years to keep units running at peak efficiency and prevent failure.
7.2 Transporting the UPS
The internal UPS batteries MUST be disconnected before transport.
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:
1. Verify that the UPS is off and disconnected from mains power.
2. Place the UPS on a flat stable surface with the front of the cabinet facing you.
3. Remove the UPS front cover
4 .Disconnect the internal battery connectors
5. Replace the UPS front cover
7.3 Storing the equipment
If you store the equipment for a long period, recharge the battery every 6 months
by connecting the UPS to utility power. The EBM charge to 90% capacity in less
than 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 passed and the batteries were never recharged do not use
them.
