2.3 Electric Installation

2N® IP Style can be fed either from an external 12V / 4 A DC power supply or from a PoE+ 802.3at supporting LAN. 


External Power Supply

For reliability reasons, use a 12 V ±15% SELV supply dimensioned to the current consumption as required for feeding of the main unit and connected extending modules.

PoE+ Supply

2N® IP Style is compatible with the PoE+ 802.3at technology and can be supplied directly from the LAN via compatible network elements. If your LAN does not support this technology, insert a PoE injector, Part No. 91378101, between 2N® IP Style and the nearest network element. This power supply provides 2N® IP Style with 21.6 W for feeding of the main unit and connected modules.

Caution

  • The PoE power supply cannot provide 2N® IP Style with a full functionality as it only offers a limited mode (Low Power Mode) for basic configuration. This way of feeding is not recommended. Connect the device to a PoE+ supply or a convenient DC supply and restart the device.
  • The PoE power supply detection is performed during the device restart.
  • If PoE supply is used and the device works in a low power mode:
    • a power problem notification is displayed in all the setting sections,
    • the display backlight is limited (to 25% of the programmable brightness value),
    • the device status indicating LED on the front side is unfunctional,
    • any module connected via the vbus cable is unfunctional.


Combined Power Supply

2N® IP Style can be fed from an external power supply and PoE+ at the same time. In this mode, the maximum power of 48 W (if a 12V / 4A DC external supply is used) or 36 W (if a 12V / 3A DC supply is used) is available for feeding the main unit and connected modules. 

Warning

  • In case the external power supply is disconnected / fails during the combined external / PoE feeding, the device will get restarted. The device will run in the Low Power Mode and a feeding problem warning will be displayed in all of the configuration sections.
  • Reconnect the device to an external power supply or PoE+ and force restart to recover the full functionality.

LAN Connection

2N® IP Style is connected to the Local Area Network (LAN) via the UTP/STP cable (Cat 5e or higher) terminated with an RJ-45 (LAN) connector. As the device is equipped with the Auto-MDIX function, you can use either the straight or crossed cable version.

Caution

  • We recommend the use of a LAN surge protection.
  • We recommend that an SSTP Ethernet cable with a shielded RJ-45 connector is used, which is connected to the switch (with the grounding option) using the same shielded connector. Thus, the device is grounded without the need to use grounding terminals.

Tip

  • Remove the protective connector cover to facilitate the threading of the UTP/STP cable RJ terminal into the device box.

Warning

  • This product cannot be connected directly to the telecommunications lines (or public wireless LANs) of any telecommunication carriers (e.g. mobile communications carriers, fixed communications carriers, or internet providers). In the case of connecting this product to the Internet, be sure to connect it via a router.

Security

  • The 12V output is used for lock connection. If, however, the unit (2N IP Intercom, 2N Access Unit) is installed where unauthorized tampering may happen (building envelopes), we strongly recommend that 2N® Security Relay (Part No. 9159010) be used for enhanced installation security.

Warning

If a coil containing device is connected, e.g. a relay / electromagnetic lock, it is necessary to protect the intercom output against voltage peak while switching off the induction load. For this way of protection, we recommend a 1 A / 1000 V diode (e.g., 1N4007, 1N5407, 1N5408) connected antiparallel to the device.
