Electrical connections
4.1 Safety instructions
4.2 Power supply
The sensor requires a minimum operating voltage of 15 VDC. The power supply is provided via
the 2-wire interface (4...20mA).
During initialisation of the sensor following values appear in the display mode of the "Measuring
value":
The specification NaN (Not a Number) disappears after a few seconds once the initialisation of
the sensor is completed. Afterwards, the measured values appear.
DANGER!
For devices used in hazardous areas, additional safety notes apply; please refer to the Ex
documentation.
DANGER!
All work on the electrical connections may only be carried out with the power disconnected.
DANGER!
Observe the national regulations for electrical installations!
WARNING!
Observe without fail the local occupational health and safety regulations. Any work done on the
electrical components of the measuring device may only be carried out by properly trained
specialists.
INFORMATION!
Look at the device nameplate to ensure that the device is delivered according to your order.
CAUTION!
Do not use the integrate 250 Ohm HART
®
resistor of the junction box SMARTMAC 200 W, when
using an Ex isolation amplifiers of third-party with integrated 250 Ohm HART
®
resistor.
