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.

Connection diagrams MODIS
Sect. 2.3 shows the block diagram of the EEx electromagnetic compact flowmeter. The power
supply (terminals 1L
½, 0L½) is connected via cable B. The PE terminal must be connected to the
protective ground conductor of the mains supply.
The IFC 090i-EEx electronics unit is provided with intrinsically safe signal in-/output circuits due to
the installed pair of MODIS modules in accordance with the table below.
