The ACS7106 is UL listed for an operating temperature range of -40º to 55ºC. Pepperl+Fuchs Comtrol, Inc. has qualified and tested the product to operate at temperatures up to 60ºC. At 60ºC, the ACS7106 can provide a maximum PoE output of 90W with an input voltage of 24VDC and 60W with an input voltage of 12VDC. For installation requiring UL60950 listing, the product should only be operated between -40º and 55ºC. If the product is operated at 60ºC, caution must be taken to not touch the hot surface of the ACS7106 enclosure.

ACS7106 Installation

Use the following procedure to install the ACS7106.

  1. Mount the ACS7106

    • Make sure that you use appropriate screws when securing the ACS7106.

    • In UL294 installations, #8 self-tapping screws can be used to mount the ACS7106. Use one or two screws on each side to mount the ACS7106.

  2. Connect the grounding screw.

    • The ACS7106 must be tied to earth ground to ensure the system meets EMC/EMI requirements.

    • Using a screw driver, loosen the earth ground screw on the side of the ACS7106 and then tighten the screw after the earth ground wire (12-14AWG) is connected.

  3. Set the DIP switch.

    The ACS7106 has a 6-pin DIP switch located on the side panel to configure the alarm relay output. The DIP switch number corresponds to the PoE and Gigabit port numbers.


    If a port is not connected, make sure that the corresponding DIP switch remains in the OFF position so that the alarm is not activated.

  4. Wire the power inputs.

    The power supply input range is 12-24VDC with a maximum power consumption of 8W without PoE PD loading. Wiring methods shall be compliant with National Electrical Code/NFPA 70/ANSI.


    Power should be disconnected from the power supply before connecting it to the switch. Otherwise, your screwdriver blade can inadvertently short your terminal connections to the grounded enclosure.

    For UL installations, the ACS7106 is intended to be used with a regulated UL Listed Class 2 or LPS (Limited Power Supply).

    For the highest specified PoE output load, the ACS 7106 is intended to be used with a regulated UL Listed Class 2 or LPS rated at:

    • 24VDC @ 4.8A or 12VDC @ 6.8A, minimum. (UL60950 Installation)

    • 24VDC @ 4.5A or 12VDC @ 6.8A, minimum. (UL294 Installation)

    1. Disconnect the power terminal block from the ACS7106.

    2. Insert the positive and negative wires into PWR+ and PWR- contacts.

    3. Tighten the wire-clamp screws to prevent the wires from being loosened.

  5. Insert the wires and set the DIP switch (above). After setting the DIP switch to ON, the relay output alarm will detect any power or port failures, and form a short circuit. The alarm relay output is Normal Open.

  6. Connect the appropriate Ethernet cables between the ACS7106 Ethernet ports and the network nodes.

    • Ports 1-4 are Fast Ethernet (10/100BASE-TX) PoE that support IEEE 802.3af/802.3at (PoE+)

    • Ports 5-6 are Gigabit (10/100/100BASE-TX)

    Half and full-duplex connections are supported with auto-negotiated link speed and duplex mode. Auto MDI/MDIX enables direct connection of another hub or switch without the need for crossover cabling. Link/Act LEDs are lit to indicate traffic and link status.


    The ACS7106 is to be connected to PoE networks without routing to outside the plant.
