When I asked the same, i was told by a pentair rep that the addition of the black gnd wire helps mediate any potential electrical "noise" on the rs485 bus due to the potential length of that cable.I wonder why Pentair Install Manual mentions connecting Black / Yellow / Green only in the RS-485 section, line #8?
