No special configuration needed for this setup.
Just create your WLAN and connect your AP to the SZ.
The only thing you need to change are the AP Reboot Timeout settings.
Those settings determine when the AP needs to reboot when it loses the connection to the vSZ.
On a vSZ High Scale you can find the settings in the AP Zone -> Advanced Options.
See screenshot attachted.
I don't know in which menu you can find it on the vSZ E but I know the option is available.
