Connecting 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.

IMPORTANT INFORMATION

notice

Make sure that the phases of the AC terminal and in the mains supply match.

This product may generate a direct current in the outer protective earthing conductor. If protective residual current devices (RCD) or residual current monitoring devices (RCM) are used, only type B ≥ 300 mA RCDs or RCMs are permitted on the AC side.

If type A RCD compatibility is activated in the device, a type A RCD can also be used.

INFO

Info

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

INFO

Info

Make sure that the phases of the AC terminal and in the mains supply match.

The 4-wire AC connection (3L/PE without N) is only possible in symmetrical networks.

 

  1. Disconnect the power supply from the mains.
  2. Secure AC connection against being switched on again.
  3. Switch the DC switch on the inverter to OFF.
  4. Correctly lay the mains cable from the power distributor to the inverter.
  5. Install the necessary safety devices – line circuit breakers, residual current circuit breakers – in the mains cable.
  7. Strip 120 mm of insulation off the mains cable.
  8. Fit suitable heat-shrinkable sleeves onto the wires. Strip insulation off ends of conductors and crimp the cable ring lug onto the ends of conductors.
  9. 30:
    Remove connection cover screws.
    Lead mains cable through connection cover.

    50/60:
    Remove screws on the bottom cover and take off the cover.
    Lead the mains cable through the feed-through into the terminal compartment of the inverter.

    Connect the mains cable to the AC terminal according to the labelling.
  11. 30:
    Attach connection cover to AC connection and screw it tight.
    Tightening torque: 1.5 Nm.

    50/60:
    Close the inverter and screw the cover tight.
    Tightening torque: 3 Nm.
  12. Seal the mains cable with sealing ring and union nut. Tighten the union nut.
  13. In countries in which a second PE connection is required, connect this at the marked place on the housing (outside).
