Commissioning the Inverter

Qualified person

Requirements:

  • The inverter must be correctly mounted.
  • The circuit breaker must be correctly rated.
  • All cables must be correctly connected.
  • Unused DC inputs must be sealed using the corresponding DC connectors and sealing plugs.
  • The country data set must be set correctly for the country or the purpose.

Procedure:

  1. Mount the enclosure lid:
      2. 817918220

    • Fit one conical spring washer to each screw. The grooved side of the conical spring washer must face the screw head.

      • 866814732

    • Position the enclosure lid with the six screws on the enclosure and tighten all screws in the sequence 1 to 6 using an Allen key (AF 5) (torque: 6 Nm ± 0.5 Nm).

      The teeth of the conical spring washer press into the enclosure lid. This ensures that the enclosure lid is grounded.

  2. Secure the protective cover using two screws and an Allen key (AF 5).
  3. Securely plug in the ESS.
  4. Switch on the circuit breaker of all three line conductors.
  5. If the multifunction relay is used, switch on any supply voltage to the load.
  • All three LEDs start to glow and the start-up phase begins. The start-up phase may take several minutes.
  • The green LED is glowing and the display alternates between the firmware version, the serial number or designation of the inverter, the NetID, the IP address, the subnet mask, the configured country data set and the display language.

    • The green LED is flashing?

    Possible cause of error: the DC input voltage is still too low or the inverter is monitoring the utility grid.

    • Once the DC input voltage is sufficiently high and the grid-connection conditions are met, the inverter will start operation.

    The red LED is glowing and an error message and event number appear in the display?
