Air Handling Space Requirements
When installing APs in an air-handling space, as described in Article 300.22(C) of the National
Electric Code® (2008 edition, pages 70-135 and 70-136), the unit should only be powered by
the Ethernet port (PoE), not by the AC-powered power supply.
Only AP822e with plastic façade removed can be applied in air-handling space.
When the product is installed in air-handling spaces, the cables employed should be suitable
under NEC Articles 300.22 and 725 and marked accordingly, for use in plenums and air-han-
dling spaces with regard to smoke propagation, such as CL2-P, CL3-P, MPP or CMP.
The products should be installed in accordance with all applicable, local regulations and prac-
tices. Compliance applies only when the plastic facade is removed from the AP.
