Combiner box - inverter disconnection

10. Combiner box - inverter disconnection
This section describes the procedure to disconnect the inverter from the combiner box.

10.1. Process of disconnecting the inverter

When disconnecting the inverter from the combiner box firstly the inverter must be actuated upon, and then the
combiner box.
1. Put the inverter to stop mode from the display.
2. Disconnect the alternating voltage (Vac).
3. Open the DC switch of the combiner box and wait five minutes for the internal capacitors to discharge.
4. Tag out the cut-off area (Vac y Vdc) in line with current regulations. Other safety measures may be
required depending on regulations.
5. Check there is no voltage.
6. If communication is via RS-485 or Ethernet it must be disconnected from the inverter.
7. Open the housing of the combiner box.
8. In the combiner box disconnect the wiring that connects the combiner box to the inverter (XPV1+, XPV1-,
XPV2+, XPV2- and PE).
The DC switch cuts the voltage at the connection terminals between the combiner box and the
inverter. Even though the DC switch is open, there will still be voltage in the inputs from the PV array
to the switch input, passing through the fuse holders. Do not touch any live components.
9. In the combiner box, remove the cable grommets and install protective caps in the holes in order to
ensure the designated level of protection.
10. Close the housing of the combiner box.
