1.1.9 Possible Dangers During Transport
Note during transport of the instrument to the installation site (especially for instruments over 50 kg):
• that the center of gravity may be off-center.
• possible obstacles into which the instrument may bump and
• protective transport items (e.g. seal plugs in openings).
1.1.10 Possible Dangers During Installation
Before installing assure that:
• the flow direction agrees with the direction indicator.
• the instrument is installed in a stress free manner (parallel axisymmetric mating flanges) and that gas-
kets suitable for the operating conditions are used.
• the required lengths of the up- and downstream straight sections are maintained.
• the pipeline up- and downstream from the flowmeter is supported.
1.1.11 Possible Dangers During Electrical Installation
• The electrical connections may only be made by qualified personnel in accordance with the electrical
Interconnection Diagrams.
• It is important to observe the information regarding the electrical connections in the Operating Instruc-
tion, otherwise the electrical Protection Class may be compromised.
• Ground the flowmeter system.
• The connections for the supply voltage must be in compliance with the applicable National and Interna-
tional Standards. A separate fuse is to be installed for each instrument, which should be located near
the instrument and appropriately identified. The Protection Class of the instrument is IP 67.
The Overvoltage Category is II (IEC664).
1.1.12 Possible Dangers when Used In Ex-Areas
Special requirements apply in Ex-Areas for the supply power, in- and output signals and the grounds. Ob-
serve the special specifications in the Chapter "Ex-Protection" in this Operating Instruction.
1.1.13 Possible Dangers During Operation
• Operation with abrasive fluids and/or cavitation can cause damage to the pressure containing parts.
• When metering hot fluids, touching the flowmeter surface could cause burns.
• Aggressive fluids can cause corrosion and/or abrasion. The pressurized fluid could prematurely leak
from the flowmeter.
STOP
Warning!
When the housing cover is removed, the EMC and personnel contact protection are voided and an electric
shock hazard exists.
Turn off supply power before opening the housing cover.
