Connecting the mains cable

DANGER

danger

Risk of death due to electrical shock and discharge!

  • De-energise device and secure against being switched on again.

CAUTION

caution

Risk of fire due to overcurrent and heating of the mains cable

If mains cables are too small, they can heat up and cause a fire.

  • Use a suitable cross-section.
  • Install line circuit breaker to secure against overcurrent.

 

INFO

Info

Whenever working inside the inverter, only ever use insulated tools to prevent short-circuits.

INFO

Info

This product may generate a direct current in the outer protective earthing conductor. A type A or B ≤ 300 mA residual current device (RCD) can be used on the AC side. Use of a type A RCD is enabled in the Webserver by going to Service menu > External hardware settings > Residual current protection equipment. (Default setting: type A RCD enabled.)

INFO

Info

Refer to the technical data for the dimensioning of the required AC line circuit breaker.

Single-wire cables (type NYY-J or NYM-J) without core end sleeves can be used with the AC terminal.

When using cables with fine wires (type H05../H07RN-F), core end sleeves must be used. Ensure that the contact length is 18 mm.

 

  1. Switch the DC switch on the inverter to OFF.
  2. De-energise the house grid.
  3. Secure home fuses against reactivation.
  4. Remove screws on the bottom cover and take off the cover.
  5. Press the lock together and remove the terminal compartment's cover.
  7. Correctly lay the mains cable from the power distributor to the inverter.
  8. Insert mains cable into the inverter and seal with sealing ring and union nut. The sealing ring can be adapted to the mains cable by peeling off the individual sealing rings from the inside to the outside. Tighten union nut to the prescribed torque.
  10. When threaded connections are not used, leave the sealing ring in the threaded connections.
  11. Connect the wires of the mains cable to the AC terminal in accordance with the labelling.
    To connect the AC cables, the inverter is equipped with spring-loaded terminal strips. The wires should be inserted into the large round openings of the terminal. Core end sleeves should be used with stranded cables.
  12. Install a residual current device and line circuit breaker in the mains cable between the inverter and the feed meter to protect it against overcurrent.
  13. In countries in which a second PE connection is required, connect this at the marked place on the housing (outside).
  2. The AC connection is connected.
