Installing an Additional Battery Module

Qualified person

Additional battery modules may only be installed in this battery cabinet within six months after its initial commissioning.

Procedure:

  1. By measuring the voltage at -POL and +POL, verify whether the DC output voltage of each new battery module is between 78.4 V and 78.6 V.
  2. If the DC output voltage of a new battery module is outside the 78.4 V to 78.6 V range, contact Service.
  3. By measuring the voltage at Charger+ and Charger-, verify whether the DC output voltage of each installed battery cabinet is in the specified range.
  4. If the DC output voltage of an installed battery cabinet is not in the specified range, contact Service.
  5. Increase the state of charge of the battery cabinets already installed to 20%. To do this, charge or discharge the battery.
  6. Disconnect the battery and battery inverter from voltage sources ( > Disconnecting from voltage sources).
  7. Mount additional battery modules in the battery cabinet.
  8. For the additional battery modules, connect the DC cables within the battery cabinet.
  9. For the additional battery modules, connect the communication cables within the battery cabinet.
  10. Recommission the individual battery cabinets.
  11. Commission the inverter.
  12. Reconfigure the inverter.
