2.6.2 LCD-W12
A special LCD-indicator, INOR LCD-W12, can be connected to the communication port of
the ProfIPAQ. It gets its power and digital data from the ProfIPAQ. The activation of the
communication port as a display connection and number of decimals to be shown in the
display are selected via the ProfiSoft software, see chapter 4. The display LCD-W12 is not
approved for mounting into Ex Hazardous area.
2.6.3 Ex Bus connection:
The models ProfIPAQ-HX and ProfIPAQ-HX/Dxy must be electrically connected via a
certified intrinsic safe power supply unit or an intrinsic safe segment coupler, which is
mounted outside the hazardous area, for use in Ex ia or Ex ib applications. For non-
incendive Ex nL applications (ProfIPAQ-H and ProfIPAQ-H/Dxy) the transmitter must be
connected to a standard power supply (Class 2 for USA). Provisions shall be made to protect
the transmitter from transient disturbances of more than 42V on power supply lines.
