PR28-17 Required Voltage

I just received the PR28-17 to use for monitoring a well pump. The provided documentation I believe is for a different, although very similar product. There’s jumpers on this board. “pull-up” and “I2C 5V”. From looking at the mechanical drawing, it appears as though I can power this device off the I2C bus, but the provided documentation says that a 12V power supply is required.

I’m guessing that I could install the jumper for I2C 5v, and connect the i2c 5v wire to the Raspberry Pi 5V, and it would work. Is this correct?

Yes, you can power up through i2c port as well.
Thanks
