10.0 STORAGE AND MAINTENANCE
10.1. Storage
Before storing, charge the UPS at least 7 hours. Store the UPS covered
and upright in a cool, dry location. During storage, recharge the battery in
accordance with the following table:
-25°C - 40°C Every 3 months 1-2 hours
10.2 Maintenance
The UPS system operates with hazardous voltages. Repairs may be carried
out only by qualified maintenance personnel.
Even after the unit is disconnected from the mains, components
inside the UPS system are still connected to the battery packs which
are potentially dangerous.
Before carrying out any kind of service and/or maintenance,
disconnect the batteries and verify that no current is present and no
hazardous voltage exists in the terminals of high capability capacitor
such as BUS-capacitors.
Only persons are adequately familiar with batteries and with the
required precautionary measures may replace batteries and
supervise operations. Unauthorized persons must be kept well away
from the batteries.
