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.
2.6 Connection diagrams MODIS
Sect. 2.3 shows the block diagram of the EEx electromagnetic compact flowmeter. The power supply
(terminals 1L
Ÿ , 0L Ÿ ) 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.
