Safety Information per EN 61010-1

• The installation and operation fo the instruments must be in
accord with the Instruction Bulletin. Deviations therefrom
could impact the safe operation of the instrument.
• Test specifications for the supply power:
see Instrument Tag or Specification Sheet.
• The cables for the supply power are in accord with the
applicable National and International standards. Each
instrument requires its own separate fuse which should be
installed close to the instrument and appropriately
identified.
• Protection Class I.
• Overvoltage Category II (IEC 664).
• The instruments are maintenance free.
• Installation and maintenance tasks are only to be performed
by trained personnel.
• There are circuits inside the housing which are hazardous
to personnel contact. Therefore the supply power should be
turned off before opening the housing.
• For overhaul or repair only original replacement parts
obtained from ABB are to be used.
• The voltage supply and the circuits for the excitation coils in
the flowmeter primary and hazardous to personnel contact.
• The excitation and signal circuits can only be connected to
the appropriate ABB flowmeter primaries. The excitation
supply cable between the converter and the flowmeter
primary is to be sized, as a function of the design type, for a
nominal voltage of 60 V AC or for the line voltage for
external voltage supplies. For the flow signal the cable
included with the shipment D173D018U02 is to be used.
