5.2.2 Field wiring
The screw clamp terminals on the module base will accommodate wire cross-sectional
areas from 0.5mm
Cable ferrules to DIN 46228 standard must be fitted toany stranded cable or
Ferrules for use with the field wiring terminals must be of length 10mm – 12mm. Figures
5.2 (a) & (b) illustrate the clamping mechanism and the need for a ferrule to reach the
inner end of the terminal. If the wires are of a cross-sectional area of 2.2mm
a hexagon profile crimping tool should be used.

5.2.3 UI module installation
To mount a UI module, ensure that the orientation is as shown in Figure 5., and insert the
bottom rear corner of the UI into the base module. Rotate it around this corner and push
firmly until the connector engages, and the clip at the top of the UI should then click into
place.
