Maintenance
The 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:
The PROTECT A. 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.
Checking the battery
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.
