1.2 Intended use
The mass flowmeters are designed exclusively to directly measure mass flow rates, product density and temperature as well to indirectly measure parameters such as the total volume and concentration of dissolved substances as well as the volume flow rate.
DANGER!
For devices used in hazardous areas, additional safety notes apply; please refer to the Ex documentation.
WARNING!
If the device is not used according to the operating conditions (refer to chapter Technical data), the intended protection could be affected.
1.3 Certifications
CE marking
The device fulfils the statutory requirements of the following EC directives:
•Low Voltage Directive 2006/95/EC
•EMC Directive 2004/108/EC
as well as
•EN 61010
•EMC specification acc. to EN 61326/A1
•NAMUR recommendations NE 21 and NE 43
The manufacturer certifies successful testing of the product by applying the CE marking.

4.5 Grounding the measuring sensor
DANGER!
There should be no difference in potential between the measuring sensor and the housing or protective earth of the signal converter!
•The measuring sensor must be properly grounded.
•The grounding cable should not transmit any interference voltages.
•Do not use the grounding cable to connect more than one device to ground.
•The measuring sensors are connected to ground by means of a functional grounding conductor FE.
•In hazardous areas, grounding is used at the same time for equipotential bonding. Additional grounding instructions are provided in the separate "Ex documentation", which are only supplied together with hazardous area equipment.

4.6 Connecting power, all housing variants
DANGER!
The device must be grounded in accordance with regulations in order to protect personnel against electric shocks.
DANGER!
For devices used in hazardous areas, additional safety notes apply; please refer to the Ex documentation.
•The protection category depends on the housing versions (IP65...67 to IEC 529 / EN 60529 or NEMA4/4X/6).
•The housings of the devices, which are designed to protect the electronic equipment from dust and moisture, should be kept well closed at all times. Creepage distances and clearances are dimensioned to VDE 0110 and IEC 664 for pollution severity 2. Supply circuits are designed for overvoltage category III and the output circuits for overvoltage category II.
•Fuse protection (IN ≤ 16 A) for the infeed power circuit, as well as a separator (switch, circuit breaker) to isolate the signal converter must be provided close to the device. The separator must be marked as the separator for this device.
100...230 VAC (tolerance range: -15% / +10%)
•Note the power supply voltage and frequency (50...60 Hz) on the nameplate.
•The protective ground terminal PE of the power supply must be connected to the separate U- clamp terminal in the terminal compartment of the signal converter
INFORMATION!
240 VAC+5% is included in the tolerance range.
24 VDC (tolerance range: -55% / +30%)
24 VAC/DC (tolerance ranges: AC: -15% / +10%; DC: -25% / +30%)
•Note the data on the nameplate!
•For measurement process reasons, a functional ground FE must be connected to the separate U-clamp terminal in the terminal compartment of the signal converter.
•When connecting to functional extra-low voltages, provide a facility for protective separation (PELV) (acc. to VDE 0100 / VDE 0106 and/or IEC 364 / IEC 536 or relevant national regulations).
INFORMATION!
For 24 VDC, 12 VDC-10% is included in the tolerance range.
