Release 08 07/2015
To protect the exposed uninstalled contacts of the components from dirt,
connect the individual system components in a dry and clean working area.

When you are selecting the installation location, make sure you observe
the climatic threshold values specified in the technical data.
Prevent heat from the surroundings from affecting the device.

Applies to devices featuring supply voltage with the characteristic value F:
Take care that the temperature of the device base plate remains under
194 °F (90 °C) during operation.
You achieve this, for example, by means of one of the following
measures:
 You make sure that the operating voltage of the device is at least 20 V.

You limit the total PoE output to a maximum of 47 W.

You limit the ambient temperature to a maximum of 149 °F (65 °C).
 You install the device on a 1.62 ft
2
(0.15 m
2
) metal plate to which you
will connect no other heat sources.

Prepare the drill holes at the installation point.

Mount the device on a level surface with four M5 screws.
2.3.1 Grounding the device
The device is grounded via the separate ground screw.
See “Device view” on page 14.
The overall shield of a connected shielded twisted-pair cable is connected to
the metal housing as a conductor.

Applies to devices featuring supply voltage with the characteristic
value A:
Use the M3 screw for the function ground.
Applies to devices featuring supply voltage with characteristic value F and
N:
Use the M4 screw for the protective ground.

Use toothed washers to ensure good electrical conductivity at the
connection.
2.4 Connecting the ferrite
Applies to devices featuring supply voltage with the characteristic value F:
To adhere to EMC conformity, you connect the ferrite supplied to the voltage
input via the power supply cable.
