•
Warning!
When the housing cover is open, EMC and contact protection is no longer provided.
The risk of death from electric shock exists.
Switch off supply power before opening housing cover.
2.1.12
Risk of explosion areas are governed by special instructions specifying how auxiliary power, signal inputs
and outputs and ground are to be connected. Follow the special information provided in the "Ex protec-
tion" chapter.

Possible risks present during transport

the center of gravity may not be in the center of the equipment.
the protective panels or protective caps fitted on the process connections of PTFE/PFA clad-
ded equipment may only be removed just before installation.
in order to prevent leaks, ensure that the cladding on the flange is not cut off and/or dam-
aged.

Possible risks present during assembly

The flow direction corresponds to the marking - if present.
The maximum torque level is observed for all flange screws.
The equipment is fitted without mechanical tension (torsion, bending), flange/intermediate flange
equipment is fitted with flush parallel mating flange and is only fitted for the anticipated operating
conditions appropriate gaskets.

Possible risks during electrical installation

Only authorised specialists may connect the equipment to the electric circuit in accordance with the
electrical diagrams.
ALWAYS note the information provided in the operating manual regarding electrical connections,
otherwise the electrical protection type may be restricted.
Earth the flowmeter system (refer to instructions in main operating manual).

Possible risks when used in Ex areas

Possible risks during active operation

During the flow of hot fluids, contact with the surface may result in burns.
Aggressive or corrosive fluids may damage the lining or electrodes. Pressurised fluids might escape
prematurely.
Pressurized medium may escape as a result of flange seal or process connection (e.g. aseptic con-
nections, tri-clamp etc.) seal fatigue.
The seal internal of flat seals of the 2000 range may become brittle as a result of CIP/SIP processes.

Possible risks during servicing and maintenance

Before removing the instrument from the pipeline , the equipment itself and if necessary adjacent
lines or containers should be depressurized.
Before opening the equipment check whether hazardous substances have been used as the flow
media. There may be hazardous residue in the equipment and this may escape upon opening.
If piping vibrations are present, we recommend securing the flange bolts and nuts to prevent them
from loosening.
I Included in the responsibilities of the system operator are periodic inspections to check:
– the walls/lining of the instrument subjected to the pressure
– the technical measuring function
