Section 2 - Installation
CPU Board Field Wiring Terminals
120 Vac Line “L” and “N” terminals:
The PCC-IV is not powered by 120Vac. Terminals 2U, 2L, 3L are connected to each other but not to any other
internal PCC circuitry. These terminals are provided for compatibility with PCC-III controllers. 120 Vac does not
need to be connected to these terminals for new PCC-IV installations. 120Vac Neutral does need to be connected
to 1U or 1L for
120 Vac DIN’s 1 thru 5 to operate correctly (terminals 4L – 8L).
