2.4 Regular IFC 090-EEx electronics unit The field cables that enter the terminal compartment of the IFC 090-EEx signal converter unit (i.e. power supply, current and binary outputs) are non-intrinsically safe. To connect external devices to the signal output terminals, the wiring requirements for the type of protection of the compartment (standard: increased safety "e", optional: flameproof "d") must be conform to the international or national standard involved (e.g. EN 60079-14).
2.5 MODIS version IFC 090i-EEx electronics unit The field cables of the non-intrinsically safe power supply and the intrinsically safe, category "ia" signal outputs enter the terminal compartment of the IFC 090i-EEx signal converter unit via two separate entrances.

The active module DC-I is needed in the 24 Vac/dc power supply version to form an active current or pulse output in combination with one of the passive modules P-SA or FA-ST. Due to limited space it is not available for 100...230 Vac supply versions.

3 Operation of the signal converter The i-EEx compact flowmeters are always equipped with magnet sensors. In that way it is possible to change the settings of the converter with aid of the magnet-bar without the necessity to open the flameproof converter housing in the hazardous area. For the program functions and settings of the converter the standard Installation and operating instructions have to be consulted.

5.3 Replacement of power fuse(s) The power fuse(s) of the different IFC 090…-EEx electronics units (regular or MODIS) have a different rating and are located on slightly different locations on the power supply printed circuit board. Only the power fuse on the 100…230 Vac power supply version of the regular IFC 090-EEx electronics unit can be reached without removing the complete unit out of the housing (only the display unit has to be unscrewed).
Regular IFC 090-EEx with 100…230 Vac power supply Note: Before commencing work, read the instructions in Sect. 5.1 ("Before opening"). Then continue as follows: 1. Remove the cover of the electronics compartment 2. Unscrew the two screws A of the display unit and turn the display unit carefully aside. 3. The fuse-holder, in which the power fuse in accordance with IEC 127-2 size Ø5 x 20 mm is mounted, is now accessible to replace the defect power fuse F1 by a new fuse with the same rating.
MODIS version IFC 090i-EEx Note: Before commencing work, read the instructions in Sect. 5.1 ("Before opening"). Then continue as follows: 1. Remove the cover of the electronics compartment 2. Unscrew the two screws A of the display unit and turn it carefully aside. 3. Disconnect the 2-pole field circuit connector (item B) and the 3-pole electrode circuit connector (item C). See figures in Sect. 5.1 and 5.2 for details. 4. Unscrew the two screws D and screw SE by a screwdriver with a long shaft (200 mm).
5.4 Changing power supply voltage This only applies to the regular IFC 090-EEx electronics unit with 100-230 Vac power supply. Note: Before commencing work, read the instructions in Sect. 5.1 ("Before opening"). Then continue as follows: 1. Remove the cover of the electronics compartment. 2. Unscrew the two screws A of the display unit and turn the display unit carefully aside. 3.
