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):

  • Network cables( > Network cable requirements)

  • Where required: Field-assembly RJ45 connector.

  • 1 conduit (trade size: 27 mm (1 in) or smaller with suitable reducer bush)

  • Sealing compound for sealing the join between the conduit and inverter if a weep hole has been added to the conduit

  • 1 rain-tight conduit fitting or conduit fitting for wet locations complying with UL 514B (trade size: 27 mm (1 in) or smaller with suitable reducing bush)

Procedure:

  1. Disconnect the inverter from all voltage sources ( > Disconnecting the Inverter from Voltage Sources).
  2. Remove filler plug from the enclosure opening for the network cables.
  3. Insert the conduit fitting into the opening and tighten from the inside using the counter nut.
  4. Attach the conduit to the conduit fitting.
  5. Guide the network cable out of the conduit into the inverter.
  6. When using a self-assembly network cable, assemble the RJ45 connectors and connect them to each network cable (see connector documentation).

  7. Insert each network cable into one of the network ports.
  8. Ensure that the network cables are securely in place by pulling slightly on them.
  9. If the inverter is installed outdoors, install overvoltage protection for all components in the network.
  10. If you would like to integrate the inverter into a local network, connect the other end of a network cable to the local network (e.g., via a router).
  11. If a weep hole has been added to the conduit, seal the conduit with sealing compound.
