PRODUCT DESCRIPTIONSHORT-FORM DATAThe POE.8AT-DC1 is a DIN rail mountable Power over
Ethernet (PoE) injector providing power for PoE
applications. It can inject full 30W to each of 8
individual PoE channels (according to IEEE 802.3at) via
RJ45 Ethernet ports, so no power sharing is limiting theuse of single channels. The device can supply powered
devices PD of type 1 and type 2 (PoE+).

1. INTENDED USEThis device is designed for installation in an enclosure and is intended for commercial use, such as in industrial control,
process control, monitoring and measurement equipment or the like.
The device is suitable for indoor applications. Outdoor applications are also allowed as long as all requirements
specified in this manual (enclosure, controlled environment, condensation, ...) are met.
Do not use this device in equipment, where malfunctioning may cause severe personal injury or threaten human life
without additional appropriate safety devices, that are suited for the end-application. If this device is used in a manner
outside of its specification, the protection provided by the device may be impaired.

2. INSTALLATION INSTRUCTIONSWARNING

Risk of electrical shock, fire, personal injury or death.

- Turn power off before working on the device and protect against inadvertent re-powering.
- Do not open, modify or repair the device.
- Use caution to prevent any foreign objects from entering into the housing.
- Do not use in wet locations or in areas where moisture or condensation can be expected.
- Do not touch during power-on, and immediately after power-off. Hot surface may cause burns.
Obey the following installation instructions:This device may only be installed and put into operation by qualified personnel.
This device does not contain serviceable parts. The tripping of an internal fuse is caused by an internal defect.
If damage or malfunction should occur during installation or operation, immediately turn power off and send unit to
the factory for inspection.
Install device in an enclosure providing protection against electrical, mechanical and fire hazards.
Install the device onto a DIN rail according to EN 60715 with the RJ45 input connectors on the bottom of the device.
Make sure that the wiring is correct by following all local and national codes. Use appropriate copper cables that aresuitable for the operating temperature of the device. Ensure that all strands of a stranded wire enter the terminal
connection. Unused screw terminals should be securely tightened. Use shielded twisted pair Ethernet cables specified
for usage in IEEE 802.3at.
The device is designed for pollution degree 2 areas in controlled environments. No condensation or frost is allowed.
The enclosure of the device provides a degree of protection of IP20. The enclosure does not provide protection against
spilled liquids.

The device can be supplied from batteries or similar DC sources. The voltage between the supply terminals and groundmust not exceed 60Vdc continuously. In order to fulfill the IEEE 802.3at requirements, the external power source andwiring connected to the supply voltage terminals need to have a minimum isolation strength of 1500Vac to ground.
Check for correct input polarity. The device will not operate when the voltage is reversed. The device must be supplied
from a PELV or SELV source or an "Isolated Secondary Circuit" in order to maintain a SELV or PELV output. A minimum
input voltage of 52Vdc is required to fulfill the IEEE 802.3at requirements with 30W (PD type 2) per channel. If thevoltage is lower than 52V, only devices with a power requirement of 15W (PD type 1) can be supplied.

There is no input inrush current limitation included. The internal input capacitor of typically 100μF will be charged
without any specific limitation means when connected to the supplying system.
Use an external circuit breaker with 6A B- or 4A C-Characteristic for the supply voltage input if the current of the
supplying source is higher than 7A.
The device is designed for convection cooling and does not require an external fan. Do not obstruct airflow and do notcover ventilation grid!

The output voltage is floating and has no ohmic connection to the ground. Type and factory tests are conducted by
the manufacturer. Field tests may be conducted in the field using the appropriate test equipment which applies thevoltage with a slow ramp (2s up and 2s down). Connect all input-terminals together as well as all output poles before
conducting the test. When testing, set the cut-off current settings to the value in the table below.
