Anyone with a Ziehl unit in the installation?

Hi,

I was hoping i could see how others have implemented the Ziehl anti islanding units in their installations.
I find the schematics in the manual a little overwhelming and would like to see examples in victron installations if possible.

Are you using one or two contactors?


Kind Regards

You need only one contactor. Use Anti-islanding-solutions-EN.pdf

The German, Austrian and French standards require two electric switching devices connected in series. The Ziehl relay controls both switching devices. Note: the second contactor is not needed for G83/2 and G59/3 compliant systems.

G83 and G59 are out of date, it is now G98 and G99 for the UK. I am not sure how many contactors are required though.

Thanks for sharing the schematic. I have a question regarding the Ziehl's communication with the Multiplus, do separate communication cables need to be run for communication, and where they will be connected on the Multiplus?
