SWG wiring

[DrewLG]

The wiring instructions and diagram in Pentair's Intellichlor installation manual seem to be all kinds of wrong, so I'm ignoring them. Please confirm that this plan is correct:

Existing wiring that I am not changing:

• 230V Intellipro pump powered from the LINE side of the EasyTouch pump relay (so it has power always).
• Intellipro communications cable connected to EasyTouch com port.
• Bond wire to Intellipro.

New wiring:

• Salt cell's cable plugged into the SWG Power Center. (This one's easy.)
• SWG Power Center's internal wiring configured for 230V because that's what my pump runs on.
• SWG Power Center powered from the LOAD side of the EasyTouch pump relay (so it has power only while the pump is running).
• SWG Power Center's communications cable connected to the EasyTouch com port in parallel with the Intellipro wires (probably by just jamming two wires under each screw -- don't tell anyone).
• Bond wire to the SWG Power Center's enclosure.

Good?

Drew,

How you outlined your wiring is perfect. It is also exactly how Pentair wants things to be wired.

I am not sure why you think that it is different than what Pentair recommends..

(so it has power only while the pump is running).

I used to say that also, because that is the intent, but what it actually does is slightly different. Wiring to the load side of the Pump/Filter Relay means that the Power Center only gets AC power when the automation is in the Pool mode, or Spa mode.. It just 'assumes' that the pump will be running, which it normally will be...

Thanks,

Jim R.

Well, there's this wiring diagram from the Intellichlor installation guide, which shows the Intelliflo pump powered from the LOAD side, only two of the SWG's four RS485 wires connected, and the +15VDC terminal mislabeled as +12VDC. And arguably shows the RS485 wires shorted together and multiple AC wires under single relay-terminal screws.

And then there's the "Connect AC Power" section of the Intellichlor Power Center manual, which seems to use "ground", "earth", and "bonding" interchangeably, and in a single paragraph seems to call one thing by four different names: "Permanent Earth Ground", "Common Earth Bonding Point", "Common Bonding Point", and "Common Approved Earth Bonding Point". Or maybe I'm misunderstanding, because they're so casual about the meanings of words. That paragraph also says weird stuff like "Do not use Intellichlor as the Common Bonding Point", as if it would occur to anyone to do so, and in bold, "Never ground pool pump to Power Center" -- I have no idea what they intended for that to mean.

Anyway, thanks very much for confirming that I'm doing it right. Can't wait to get the thing fired up and producing chlorine.
