•
Shorts for in/output functions: CO= current output, PO=Pulse Output, SO= Status Output, CI= Control Input,
PA=Profibus PA, FF=Foundation Fieldbus, DP=Profibus DP
•
All in/outputs are passive unless otherwise noted as active (a)
•
n.c. = not connected
•
The I/O circuits named Ex i I/O, Ex i Option are always in type of protection Intrinsic safety (EEx ia). The I/O circuits
Fieldbus I/O Profibus PA and Fieldbus I/O Foundation Fieldbus can be in type of protection Intrinsic safety.
•
A maximum of 4 intrinsically safe (EEx ia) in/outputs are possible. All intrinsically safe circuits are galvanically
insulated with respect to earth and to each other. To avoid summation of voltages and currents, the wiring of these
EEx ia circuits must be sufficiently separated, e.g. in line with the requirements of standard EN IEC 60079-14,
section 12.2.
•
The EEx ia signal in/outputs may only be connected to other EEx ia or ib certified device (e.g. intrinsically safe
isolation amplifiers), even if such devices are installed in the non-hazardous area!
•
Connection to a non-EEx i apparatus cancels the EEx ia properties of the flowmeter.
•
Terminals L, N (or L+, L-) for mains connection are always non-intrinsically safe. To achieve the necessary spatial
separation to EN 50 020 between the non-EEx i and EEx i circuits the mains terminals are provided with a semi-
circular insulation cover with a "snap-in" lock. This cover has to be closed before powering up the converter.
•
Note: For converters with an EEx e terminal compartment, it is allowed to open this compartment in an energized
state for short periods and to access the intrinsically safe terminals for possible checks provided the semi-circular
insulation cover over the non-intrinsically L, N (L+, L-) terminals is kept closed.
