2.3 Storage
•Store the device in a dry, dust-free location.
•Avoid continuous direct sunlight.
•Store the device in its original packing.
•Storage temperature: -40...+70°C / -40...+158°F
2.4 Transport
Signal converter
•No special requirements.
Compact version
•Do not lift the device by the signal converter housing.
•Do not use lifting chains.
•To transport flange devices, use lifting straps. Wrap these around both process connections.
2.5 Installation specifications
INFORMATION!
The following precautions must be taken to ensure reliable installation.
•
Make sure that there is adequate space to the sides.
•
Protect the signal converter from direct sunlight and install a sun shade if necessary.
•
Signal converters installed in control cabinets require adequate cooling, e.g. by fan or heat
exchanger.
•
Do not expose the signal converter to intense vibration. The flowmeters are tested for a
vibration level in accordance with IEC 68-2-64.

2.6 Mounting of the compact version
2.7 Mounting of the wall housing, remote version
1 Prepare the holes with the aid of the mounting plate.
2 Fasten the device securely to the wall with the mounting plate.
INFORMATION!
The signal converter is mounted directly on the measuring sensor. For installation of the
flowmeter, please observe the instructions in the supplied product documentation for the
measuring sensor.
INFORMATION!
Assembly materials and tools are not part of the delivery. Use the assembly materials and tools
in compliance with the applicable occupational health and safety directives.

3.1 Safety instructions
3.2 Important notes on electrical connection
DANGER!
All work on the electrical connections may only be carried out with the power disconnected. Take
note of the voltage data on the nameplate!
DANGER!
Observe the national regulations for electrical installations!
WARNING!
Observe without fail the local occupational health and safety regulations. Any work done on the
electrical components of the measuring device may only be carried out by properly trained
specialists.
INFORMATION!
Look at the device nameplate to ensure that the device is delivered according to your order.
Check for the correct supply voltage printed on the nameplate.
DANGER!
Electrical connection is carried out in conformity with the VDE 0100 directive "Regulations for
electrical power installations with line voltages up to 1000 V" or equivalent national
specifications.
CAUTION!
•
Use suitable cable entries for the various electrical cables.
•
The measuring sensor and signal converter have been configured together at the factory. For
this reason, please connect the devices in pairs. Ensure that the measuring sensor constant
GKL (refer to information on the nameplates) are identically set.
•
If delivered separately or when installing devices that were not configured together, set the
signal converter to the DN size and GKL of the measuring sensor.

3.3 Electrical cables for remote device versions, notes
3.3.1 Notes on signal cable A
Observe the following notes:
•Lay the signal cable with fastening elements.
•It is permissible to lay the signal cable in water or in the ground.
•The insulating material is flame-retardant to EN 50625-2-1, IEC 60322-1.
•The signal cable does not contain any halogens and is unplasticized, and remains flexible at
low temperatures.
•The connection of the inner shield (10) is carried out via the stranded drain wire (1).
•The connection of the outer shield (60) is carried out via the stranded drain wire (6).
3.3.2 Notes on field current cable C
INFORMATION!
Signal cable A (type DS 300) with double shield ensures proper transmission of measured
values.
DANGER!
A shielded 2-wire copper cable is used for the field current cable. The shielding MUST
