Installation

Powering the Sensor from 24 VDC

The Airnet II 4-Channel particle sensor can be powered with sources other than the
Power over Ethernet (PoE). The unit may also be powered using a source of 24 VDC
power (if this option was ordered) that may be connected to multiple Airnet II 4-
Channel particle sensors. Ensure that the 24 VDC supply wiring is sized 18 AWG (0.75
2
mm ) minimum and the supply is current limited to 8 A maximum or fused at 5A
maximum.
If using a local power source a receptacle and crimp pins are available that attach to
the ends of the power cable. The crimp pins are then inserted into the provided 12-pin
Molex™ Micro Fit receptacle.

Powering the Sensor from Power over Ethernet (PoE)

The Airnet II 4-Channel can be powered from a Power over Ethernet Router or Injector
that conforms to IEEE 802.3af. A shielded CAT5 cable must be used or a local ground
connected to the sensor for proper operation when using PoE.
