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.
10.2.2Battery 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).
10.2.3Ventilator 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).
10.3Battery 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.
