I just ordered a HPWC and will get a 2nd one in the coming months. Can anyone say if there's any issue running the serial connection inside the same conduit as the power conductors? Cat 6 cable re-purposed for RS485 is rated for 600v and is twisted pair for common mode rejection, right? right???? lol.
I used a shielded cable and also ran it in a separate conduit. A bit of overkill but I saw no reason to risk interference.
