3 Phase wire scheme

Can you confirm wiring for 2 contactors in order to switch between 1P and 3P charging should be like this? (If so, can you update the manual as well?)

That is correct, it felt for us to be the safest setup. For example: with 2x 2P in parallel you could have 2 live fase wires without the neutral if for some reason the contactors aren't working/controlled correctly.

Below a complete setup when already having an existing installation and the EVSE is placed in a new cabinet. Of course, many variations are possible depending on local regulations. This setup at least was approved in Belgium. Some remarks:

• The type B diffs are important as a 6mA DC leak current protection must be in place.
• When having a type B diff it not allowed/not safe to have upstream type A diffs
• Having a 300mA diff is mandatory in Belgium
• The 30mA diff is for extra safety as the cable is meant for outside
• Putting the 300mA Type B in parallel on the 300mA Type A with 16mm² can be challenging, as both cables need to be in the diff sockets (regulation) I used a 80A 300mA Type A which has wide enough clamps, so both cables could be inserted. I put both cables in a 2x16mm² cable sleeve first and then inserted the sleeve into the clamps
