DANGER

Danger to life due to electric shock in case of overvoltages and if surge protection is missing

Overvoltages (e.g., in the event of a flash of lightning) can be further conducted into the building and to other connected devices in the same network via the network cables or other data cables if there is no surge protection. Touching live parts and cables results in death or lethal injuries due to electric shock.

  1. Ensure that all devices in the same network are integrated in the existing overvoltage protection.
  2. When laying the network cable outdoors, ensure that there is suitable surge protection at the network cable transition from the product outdoors to the network inside the building.
  3. The Ethernet interface of the product is classified as "TNV-1" and offers protection against overvoltages of up to 1.5 kV.

Additionally required material (not included in the scope of delivery):

  • 1 network cable

Network cable requirements:

The cable length and quality affect the quality of the signal. Observe the following cable requirements:

  • Cable type: 100BaseTx

  • Cable category: minimum Cat6

  • Plug type: RJ45 of Cat6 or higher

  • Shielding: S/UTP, F/UTP or higher

  • Number of insulated conductor pairs and insulated conductor cross-section: at least 2 x 2 x 0.22 mm²

  • Maximum cable length between two nodes when using patch cables: 50 m

  • Maximum cable length between two nodes when using installation cables: 100 m

  • UV-resistant if installed outdoors.

Router requirements:

  • DHCP support via the Internet router, with MAC binding is recommended. If DHCP is not supported, an IP address from the address range of the router must be assigned manually to each device.

  • Fast Ethernet with 100 Mbit/s data transfer rate

Procedure:

  1. Disconnect the product from voltage sources ( > Disconnecting the product from voltage sources).
