Cable sizing for this example

Use the diagram as a starting point for your installation. Replace the example equipment and cable lengths with your own, and check the connections against your exact model's instructions.

Cable sizes depend on the connected equipment, current and cable lengths. Add those details in Crimp to size each run.

Fit check

Connect it to the rest of your system.

Describe your setup to draft a system with ES900 connected. Review the selected parts and cable lengths, then edit the diagram in Crimp.

The model only picks parts and draws the connections. Every wire size and fuse rating still comes from Crimp's own sizing, never from the model.
