head.
• For an electronic pump, wire RS485 / Current Loop / Tokheim communication cable from
the CFN PLUS to the pump head.
• Wire one 0.4" (10 mm) ground cable from the Mains ground connection to the pump
chassis.
• The communication cable shield must be connected to ground at one end-side only,
preferably at the controller installation side (see Figure 2-10).
