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. 

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). 

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). 

 

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.
