I bought a used Gen 2 HPWC but one connector is missing - CNA11.

Does anyone have a schematic or where the wires go from CNA11. I’m guessing there’s two wires and they monitor the output after the relays but wanted to be sure before I hook it up.

I saw that but it doesn’t make sense.

On my HPWC there’s a ground and two hots (green, red and black). The schematic above shows 4 wires.

Thanks but it doesn’t show the connector. I just need a picture of the wiring. Hopefully someone has that.

The schematic you have above is for the 3-Phase, 32A Europe/Asia version of the Wall Connector: https://www.tesla.com/sites/default...ll-connector-installation-manual-en-EU-v1.pdf

The model you want is the North America/Japan 80A version: https://www.tesla.com/sites/default...a-wall-connector-installation-manua-en-v1.pdf

The North America/Japan version is only going to have two conductors and a ground. According to the manual, you select whether the two conductors are hot/neutral or hot/hot via a switch inside the HPWC, and you select the voltage via a rotary switch.

Thanks. That confirms to me that pin 1 and pin 10 on CNA11 monitor the output.

Correction:
Source voltage is defined (240 no neutral, 277 w/neutral) using DIP switches. Current is set using a rotary switch.
