Electrical Interconnections, Converter

2.4.1 Supply Power Connections

The supply power, which should conform to the specifications
listed on the instrument tag, is connected to terminals L (Phase)
and N (Neutral) or 1L1 and 1L2 over a mains fuse and a
mains switch. The cable cross section of the supply power
connections and the installed fuse size must be compatible
(VDE 0100). The housing is grounded by connecting the
terminal to ground.
!
Warning:
Observe the supply power limits (values listed in
the Specification Sheet). The voltage drop in the
supply power leads for the 24/48 V AC design must
be considered when long cables with small cross
sections are installed.
The connections are to be made in accordance with the
Interconnection Diagrams beginning on Page 7.

2.4.2 Magnet Coil Supply

The magnet coil supply varies as a function of the flowmeter
size! The appropriate Interconnection Diagrams are to be used!
Flowmeter Primaries 1/10" to 16" [DN 3 to DN 400]:
The magnet coils are supplied directly from the converter over
terminals M1, M3 with a shielded cable, e.g. 2x1.5 mm
Excitation voltage approx. 60 V AC, 50/60 Hz.
Flowmeter Primaries 20" to 40" [DN 500 to DN 1000]:
The magnet coils are supplied from a line supply and not from
the converter. Assure that the flowmeter primary and the
converter are both supplied over a single mains switch and a
single mains fuse.
Supply power 115/230 V AC, 50/60 Hz.
Flowmeter Primaries 10DS3112 in Ex-Design:
The magnet coiuls are supplied directly from the converter over
terminals F1, F3 with a shielded cable, e.g. 2x1.5 mm
Excitation voltage approx. 12 V AC, 50/60 Hz.
Flowmeter Primaries 10DS3111, 10DS3121
in Ex-Design:
The magnet coils are supplied directly from the converter over
terminals M1, M3 with a shielded cable, e.g. 2x1.5 mm
Excitation voltage approx. 48 V AC, 50/60 Hz.
!
Check converter Model Number, the correct
coordination with the Ex-Flowmeter Primary type
must be assured . (See converter and flowmeter
primary Instrument Tags).
!
Warning:
The signal in- and output circuits may only be
connected to circuits which are not hazardous to
personnel contact (EN 61010-1).

2.4.3 Power

The connection voltage and the current for the flowmeter
primary are listed on the Instrument Tag. The cable cross-
section for the supply power and the fuse size must be
compatible (VDE 0100).
