Checking the Mounting and Connection Work

Qualified person

Before commissioning or during setup, perform a thorough check of all mounting and connection work. The basis for the check is DIN VDE 0100-600.

Procedure:

  1. Ensure that the inverter has been correctly mounted and connected.
  2. Ensure that the battery has been correctly mounted and connected. In particular, ensure adherence to the requirements for the installation site and the local fire protection regulations.
  3. If there is a DC distributor present: Ensure that the DC distributor has been correctly mounted and connected.
  4. Ensure that all battery cabinets have been mounted correctly.
  5. With a single battery cabinet: Ensure that all electrical connections on the battery cabinet have been established.
  6. With multiple battery cabinets: Ensure that only the grounding is connected on the battery cabinets, and that no other electrical connections have been made. The connections will first be made during the commissioning process.
  7. Ensure that the energy meter has been correctly mounted and connected (see manual for the energy meter).
  8. Measure the ground resistance and continuity of the grounding conductor.
  9. Measure the insulation resistance.
  10. Check the polarity between the inverter and battery.
  11. With a DC distributor present: Ensure that the circuit breaker of the DC distributor is switched on.
