• The Temperature Classes, a function of the ambient and fluid temperatures, is listed in the EU-Type Examination Certificate.
• The supply voltage value for the converter is listed on the Name Plate.
• The Ignition Type for the output circuits is defined by the external circuits connected. It can be configured as all „intrinsically safe“ or
„non-intrinsically safe“. A combination of „intrinsically safe“ and „non-intrinsically safe“ is not permissible. The test voltage for the
output circuits for both Ignition Types is U
T
= 60 V.
• The safety specifications for intrinsically safe circuits may be found in the EU-Type Examination Certificate.
• Care should be exercised to assure that the cover over the supply power connections is correctly installed. For intrinsically safe
output circuits the connection area may be opened.
• It is recommend that the cable connectors, included with the shipment, used for the output circuits correspond to the Ignition
Type: intrinsically safe

light blue; non-intrinsically safe
→
black.
• The flowmeter primary and the converter housing are to be connected to Potential Equalization.
For intrinsically safe circuits, Potential Equalization is to be maintained along the entire circuit.
• The interior of the meter pipe for all flowmeter primaries in sizes DN 50 to DN150 [2” to 6”] is classified Category 1 (Zone 0), that for
meter sizes
≤
DN 40 [1-1/2”] only corresponds to Category 2 (Zone 1). The Temperature Classes as a function of the ambient and
maximum fluid temperatures are listed in the table.
• If the flowmeter primary is to be insulated, the max, insulation thickness is 100 mm.
The converter housing may not be insulated.
• The corrosion resistance of the meter pipe materials to the fluid must be considered.
Insulation
The pipeline and the flowmeter primary insulation is to be
installed as follows.
The max. insulation thickness is 100 mm.
