Anybody installed ICS vehicle charger?

grahamro

I'm faced with the prospect of installing 2x22kW ICSWT22C EV chargers.
These are being promoted by CEF. I've downloaded the 400v installation instructions and had a look at a 230V version in local branch.
The manufacturers state built in current detection AC 30mA DC 6mA which would suggest a type A RCD, also goes onto say no earth rod required on TN-C-S system which would suggest O-PEN protection. There's only electronics on the pcb and no sign of a BS61008 or other type of RCD.
When I asked what BS EN number the RCD complied with re. reg. 722.531.3.101 I didn't get a comprehensive answer which would suggest that there is no RCD to 722.531.3.101 and I should fit some sort of RCD upstream.
The installation instructions also mention that these units comply with BS 7671 18th edtn. AMD 1 and that an upstream 30mA RCD need only be fitted when connecting to the main supply via a flexible cable.
So anybody out there with any experience of these units?
