All conduits in the pedestal should terminate into a seal-off. The seal must be the first fitting where the
conduit emerges from grade. Install 1/2” (1.3 cm) or 3/4” (1.9) rigid steel conduits, as applicable, to the area
where the pedestal is to be located:
l
To the PV200 power source.
l
To other PV200 terminals or external Fuel Site Controller (FSC) junction box for Petro-Net
communications.
l
To the remote communication access panel for phone line(s), Ethernet.
l
To each mechanical pump or dispenser for control and pulser wires (for pedestal mounted PCMs only).
l
To each electronic dispenser for communication wires (for an internal FSC with a DPC board installed
in the pedestal only).

4.1.1 Petro-Net Wiring
The PV200, PCMs, FSC and other devices communicate using an RS-485 protocol called Petro-Net
™
.
Petro-Net wiring is a twisted-pair of 18 AWG wires that must be twisted together to provide immunity to
electrical noise. You can order Petro-Net from OPW as Part #: 12-1029.
Petro-Net wiring can run a maximum of 5,000' (1,524 m).
