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 inverter is classified as "TNV-1" and offers protection against overvoltages of up to 1.5 kV.

NOTICE

Damage to the inverter due to moisture ingress

Moisture penetration can damage the inverter and impair its functionality.

  1. Connect the network cable with the supplied RJ45 protective sleeve to the inverter.

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 CAT5e

  • Plug type: RJ45 of Cat5, Cat5e or higher

  • Shielding: SF/UTP, S/UTP, SF/FTP or S/FTP

  • 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 (164 ft)

  • Maximum cable length between two nodes when using installation cables: 100 m (328 ft)

  • UV-resistant for outdoor use.

Procedure:

  2. Unscrew the protective cap from the network port.
  3. Press the cable support sleeve out of the threaded sleeve.
  4. 2371694220
  5. Thread the swivel nut and threaded sleeve over the network cable. At the same time, thread the network cable through the opening in the cable support sleeve.

  9. Plug the network cable connector into the network port on the inverter and screw the threaded sleeve onto the network port thread on the inverter.
  10. 2371694988
  11. Screw the swivel nut onto the threaded sleeve.
  12. If you would like to establish a direct connection, connect the other end of the network cable directly to the end device.
  13. If you would like to integrate the inverter into a local network, connect the other end of the network cable to the local network (e.g., via a router).
