If there are several inverters and only one battery in the system, the battery should be connected to the inverter that is to be configured as the System Manager.
Additionally required material (not included in the scope of delivery):
Where required: Field-assembly RJ45 connector.
Sealing compound for sealing the join between the conduit and inverter if a weep hole has been added to the conduit
1 rain-tight conduit fitting or conduit fitting for wet locations complying with UL 514B (trade size: 19.05 mm (0.75 in) or smaller with suitable reducing bush)
Procedure:
- Disconnect the inverter from all voltage sources ( > Disconnecting the Inverter from Voltage Sources).
- When using a self-assembly network cable, assemble the RJ45 connectors and connect them to the network cable (see connector documentation).
- Remove the filler plug from the middle enclosure opening.
- Insert the conduit fitting into the opening and tighten from the inside using the counter nut.
- Run the network cable through the conduit into the inverter.
- Attach the conduit to the conduit fitting.
- Plug the network cable into the BATTERY network connector.
- Tug lightly to ensure that the network cable is secure.
- Connect the network cable to the battery (see battery manual).
- If a weep hole has been added to the conduit, seal the conduit with sealing compound.
