7 Maintenance
The PROTECT B. consists of advanced and resistant
components. To guarantee a continuous and high availability it is
recommended to check the unit (especially the batteries and the
fans) in regular intervals (at least every 6 months).
CAUTION:
Follow safety and security regulations
unconditionally!
Visual control
When going through the visual control check whether:
♦ mechanical defects or foreign matter is visible in the
system
♦ conducting dirt or dust sediments are in the unit and
♦ dust sediments prevent optimal ventilation in and out
the unit.
CAUTION:
Before going through the next step disconnect
the PROTECT B. from the mains.
If the unit is very dusty it is recommended to clean the UPS
with compressed air to enable optimal ventilation.
The time intervals for the visual control depend mainly on the
local situation at the deployment site.
Battery control
The aging process can be detected by regular capacity
probes. Make comparison measurements every 12 month e.g.
by simulating a power failure and check how long the standby
time lasts. The load should always be the same for each
simulation. Dramatic changes compared to the last
measurements require a change of batteries. Contact your
local dealer or call our hotline (see page 4).
