I’m about to add an ET112 energy meter to the main DB, and I’ve got to route the RS485 communications cable to the Cerbo on the other side of the room.

I’ve got the Cat5 communications cable between the Cerbo and inverter running in the same trunking as the battery cables, and now I’m wondering that if the above is not allowed, whether this will be red-flagged as well:
