2 ELECTRICAL CONNECTION 2.1 Equipotential bonding system The IFM 4080 K-EEx and IFM 4080 K / i-EEx flowmeters must always be incorporated into the equipotential bonding system of the hazardous area. This connection can be achieved through the PE/FE conductor connected to the PE terminal in the terminal compartment (see figure 1) or through a separate PE conductor, cross sectional area at least 4 mm connected to the external PE clamp, placed below the converter housing. -

The PE (or FE) conductor must be connected to the press-fitted M5 clamp terminal marked inside the terminal compartment. This conductor must be guided through the rectangular opening in the metal dividing plate that separates the non-intrinsically safe power supply terminals from the intrinsically safe signal in-/output terminals. - Page 10 MODIS modul Nominal values for voltage and current P-SA Current: 4 .. 20 mA (passive current output ) Working voltage: 8 .. 30V Voltage drop : 8V at 4mA FA-ST Working voltage: 6 .. 30V (frequency/pulse/status output Working current: < 110 mA or control input) Voltage drop: in ON-state: <...
- Page 11 The flameproof terminal feed-through has seven terminals in total, the top two terminals are used for connection of the power supply, the third one is only used for mounting of a metal dividing plate with insulating cover plate. The remaining four are used for the intrinsically safe signal in-/output circuits of the installed MODIS modules.
