CAUTION:
PROTECT C. 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
largely determined by the site conditions.
7.2.2 Checking the Battery
Progressive ageing of the battery system can be detected by
regular capacity checks. Every 6 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.
Please contact our hotline if the time drops drastically
compared to the previous measurement (see page 4).
7.2.3 Fan Checking
Regularly check the fans for dust build-up and noticeably
untypical noise development. Clean the intake openings if
they are blocked. Contact our hotline if a fan is running
unusually loud or irregularly (see page 4).
