CAUTION!
Before performing the next step, make sure to
switch off the voltage supply to the PROTECT D.
If a large amount of dust has accumulated, the device should be
carefully cleaned with dry compressed air to allow for better heat
exchange.
The time intervals of the visual checks to be performed largely
depend on where the devices are installed and the
environmental conditions at these locations.
10.2.2 Battery check
You can tell whether the batteries are getting older by making
regular capacity tests. Every six months, make comparative
checks with respect to the bridging time possible by, for
example, simulating a power outage. The load should always
show close to the same power requirements. If the battery time
sinks drastically compared to the previous check, please contact
our hotline (see pg. 5).
10.2.3 Ventilator check
Check the ventilators regularly for dust accumulation and any
noticeably irregular noises. If the vents are clogged, they must
be cleaned; if the ventilator appears to be unusually loud or is
not operating smoothly, please contact our hotline (see pg. 5).
10.3 Battery replacement
CAUTION!
A battery can present a risk of electrical shock and
can be very dangerous if handled improperly.
The following precautions should be observed
before replacing the batteries:
 Remove rings, watches and other metal objects.
 If the battery replacement kit is damaged in anyway or shows
signs of leakage, contact your dealer immediately.
 Properly recycle or dispose of used batteries. Do not dispose
of batteries in a fire. The batteries may explode.
