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.
11.2.2 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 page 7).
11.2.3 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
page 7).
11.3 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 any way or shows signs of leakage,
contact your dealer immediately.
• Recycle or dispose used batteries properly. Do not dispose of batteries in a fire.
The batteries may explode.
