Connecting the Measuring Cable of the Multicluster-Box 12

Qualified person

Requirements:

  • The inverters to be connected must be Sunny Island 6.0H / 8.0H inverters.

  • The utility grid must be connected to the multicluster system (see Multicluster-Box 12 operating manual).

Procedure:

  1. On every Sunny Island of the main cluster, connect the measuring cable for voltage monitoring of the Multicluster-Box 12 to ExtVtg. First connect the wires of X112 3 and X112 4 at the master to ExtVtg ( > Connecting ExtVtg).
  2. Connect the conductors of X112 3 and X112 4 on the master to ExtVtg on each Sunny Island of the main cluster.
  3. Connect the conductors of X112 7 and X112 8 on Slave 1 to ExtVtg on each Sunny Island of the main cluster.
  4. Connect the conductors of X112 9 and X112 10 on Slave 2 to ExtVtg on each Sunny Island of the main cluster.
  5. The measuring cable for voltage monitoring from the Multicluster Box 12 is connected.
  6. At the master of the Main Cluster, connect the AC contactor monitoring. To do this, first connect BatVtgOut- with DigIn- within the master( > Connecting BatVtgOut, DigIn, BatTMP and BatCur).
  7. Thread both insulated conductors through a ferrite included in the scope of delivery.
  8. Connect the insulated conductor from X113 3 to BatVtgOut+.
  9. Connect the insulated conductor from X113 4 to DigIn+.
  10. The monitoring of the grid contactor is connected.
