Siemens Indoor air quality sensors QPA10x4 A6V101099173_en--_b
Building Technologies 2018-05-01
Engineering notes
The sensor must be powered by a transformer for safety extra low-voltage (SELV) with
separate windings, suited for 100 % duty.
On applications with EMC problems, use shielded cables. For secondary power lines
and signal lines, use twisted-pair cables.
Mounting notes
Inner wall of the room to be ventilated, not in niches, not behind curtains, not above or
near heat sources, and not exposed to direct light from spot lights.
Do not expose the sensor to direct solar radiation.
Seal the end of the conduit at the sensor to prevent false measurements due to drafts
through the conduit.
Mounting instructions are enclosed in the package.
Disposal
The device is considered electrical and electronic equipment for disposal in terms of the
applicable European Directive and may not be disposed of as domestic garbage.
· Dispose of the device through channels provided for this purpose.
· Comply with all local and currently applicable laws and regulations.
