Protect A consists of state-of-the-art, non-wearing components. We
do, however, recommend regular visual checks of the unit to maintain
its continuous availability and operational reliability. Check whether:
• there is any mechanical damage or foreign bodies can be found
in the system,
• any conductive dirt or dust has accumulated in the unit,
• accumulation of dust affects heat supply and dissipation.
CAUTION:
CAUTION:CAUTION:
CAUTION:
UPS must be disconnected from the power supply prior to carrying
out the following work.
If large quantities of dust have accumulated, the unit should, as a
precaution, be cleaned with dry compressed air, in order to ensure
adequate heat dissipation.
The intervals at which visual checks should be performed are
primarily determined by the site conditions.

Progressive ageing of the battery system can be detected by regular
capacity checks. Every 12 months, perform measurements to compare
the achievable standby times, e.g. by simulating a mains failure. In this
case, the load should always have approximately the same capacity
demand. Have the battery system renewed if the time drops
drastically compared to the previous measurement.
