2.1 Important information
Be sure to take note of the following
information in order to ensure proper
functioning of the signal converter.
Please note:
1) Overvoltage class:
In conformity with VDE 0120, equivalent
to IEC 664, the compact flowmeters are
designed for overvoltage category III in
the supply circuits and overvoltage
category II in the output circuits.
2) Safety isolation:
The compact flowmeters must be
provided with an isolating facility.
Electrical connection and repairs may only
be carried out by qualified personnel.
•
Protect the flowmeter from direct radiant
heat (e.g. hot-product tanks), insulate if
necessary.
•
Do not expose flowmeter to intense
vibration. If necessary, support the
pipeline to the right and left of the
flowmeter. Level of vibration in accordance
with IEC 068-2-34: below 2.2g in the 20 -
2000 Hz frequency range.
•
Note information given on the instrument
nameplate, voltage.
•
The FE functional ground for the supply
power should for measurement reasons be
connected to the separate U-clamp
terminal on the signal converter housing.
•
When connected to a functional extra-
low voltage of 24 V DC, protective
separation (PELV) must be ensured (VDE
0100 / VDE 0106 or IEC 364 / IEC 536 or
equivalent national regulations)..
