Inflowing medium
Do not mount the instrument in or above the
filling stream. Make sure that you detect the
product surface, not the inflowing product.

Preparing the connection

Safety instructions
Always keep in mind the following safety
instructions:
•
Carry out electrical connection by trained,
qualified personnel authorised by the plant
operator
•
If overvoltage surges are expected, overvol-
tage arresters should be installed
Warning:
Only connect or disconnect in de-ener-
gized state.
Voltage supply
Power supply and current signal are carried on
the same two-wire cable. The operating voltage
can differ depending on the instrument version.
The data for power supply are specified in chap-
VEGAPULS WL S 61 • 4 ... 20 mA

5 Connecting to power supply

ter "Technical data".
Provide a reliable separation between the
supply circuit and the mains circuits according
to DIN EN 61140 VDE 0140-1.
Power the instrument via an energy-limited cir-
cuit acc. to IEC 61010-1, e.g. via Class 2 power
supply unit.
Keep in mind the following additional factors
that influence the operating voltage:
•
Lower output voltage of the power supply
unit under nominal load (e.g. with a sensor
current of 20.5 mA or 22 mA in case of fault)
•
Influence of additional instruments in the
circuit (see load values in chapter "Technical
data")
Connection cable
The instrument is connected with standard
two-wire cable. If electromagnetic interference
is expected which is above the test values of
EN 61326-1 for industrial areas, screened cable
should be used.
Screened cable generally necessary in HART
multidrop mode.
