Installation and Commissioning
Devices are to be connected under dead-voltage condition. Devices
must only be connected to safety extra-low voltage. Consequential
damages caused by a fault in this device are excluded from warranty or
liability. These devices must be installed and commissioned by authorised
specialists. The technical data and connecting conditions shown on the
device labels and in the mounting and operating instructions delivered
together with the device are exclusively valid. Deviations from the
catalogue representation are not explicitly mentioned and are possible
in terms of technical progress and continuous improvement of our
products. In case of any modifications made by the user, all warranty
claims are forfeited. Operating this device close to other devices that
do not comply with EMC directives may influence functionality. This
device must not be used for monitoring applications, which serve the
purpose of protecting persons against hazards or injury, or as an
EMERGENCY STOP switch for systems or machinery, or for any other
similar safety-relevant purposes.
Dimensions of enclosures or enclosure accessories may show slight
tolerances on the specifications provided in these instructions.
Modifications of these records are not permitted.
In case of a complaint, only complete devices returned in original packing
will be accepted.
Notes regarding mechanical mounting and attachment:
Mounting shall take place while observing all relevant regulations and
standards applicable for the place of measurement
(e.g. such as welding instructions, etc.). Particularly the following
shall be regarded:
– VDE ⁄ VDI directive technical temperature measurements,
measurement set - up for temperature measurements.
– The EMC directives must be adhered to.
– It is imperative to avoid parallel laying of current-carrying lines.
– We recommend to use shielded cables with
the shielding being attached at one side to the DDC ⁄ PLC.
Before mounting, make sure that the existing thermometer's techni-
cal parameters comply with the actual conditions at the place of
utilization, in particular in respect of:
– Measuring range
– Permissible maximum pressure, flow velocity
– Installation length, tube dimensions
– Oscillations, vibrations, shocks are to be avoided (< 0.5 g)

Important notes
Our "General Terms and Conditions for Business" together with the "General Conditions for the Supply of Products and Services of the Electrical and
Electronics Industry" (ZVEI conditions) including supplementary clause "Extended Retention of Title" apply as the exclusive terms and conditions.
In additionIn addition, the following points are to be observed:
– These instructions must be read before installation and putting in operation and all notes provided therein are to be regarded!
– A suitable weather and sun protection hood must be used when installed outdoors.
– Devices must only be connected to safety extra-low voltage and under dead-voltage condition. To avoid damages and errors the device
(e.g. by voltage induction) shielded cables are to be used, laying parallel with current-carrying lines is to be avoided, and EMC directives are
to be observed.
– This device shall only be used for its intended purpose. Respective safety regulations issued by the VDE, the states, their control authorities,
the TÜV and the local energy supply company must be observed. The purchaser has to adhere to the building and safety regulations and has
to prevent perils of any kind.
– No warranties or liabilities will be assumed for defects and damages arising from improper use of this device.
– Consequential damages caused by a fault in this device are excluded from warranty or liability.
– These devices must be installed and commissioned by authorised specialists.
– The technical data and connecting conditions of the mounting and operating instructions delivered together with the device are exclusively valid.
Deviations from the catalogue representation are not explicitly mentioned and are possible in terms of technical progress and continuous
improvement of our products.
– In case of any modifications made by the user, all warranty claims are forfeited.
– This device must not be installed close to heat sources (e.g. radiators) or be exposed to their heat flow. Direct sun irradiation or heat irradiation
by similar sources (powerful lamps, halogen spotlights) must absolutely be avoided.
– Operating this device close to other devices that do not comply with EMC directives may influence functionality.
– This device must not be used for monitoring applications, which serve the purpose of protecting persons against hazards or injury,
or as an EMERGENCY STOP switch for systems or machinery, or for any other similar safety-relevant purposes.
– Dimensions of housing or housing accessories may show slight tolerances on the specifications provided in these instructions.
– Modifications of these records are not permitted.
– In case of a complaint, only complete devices returned in original packing will be accepted.
Commissioning is mandatory and may only be performed by qualified personnel!
These instructions must be read before installation and commissioning and all notes provided therein are to be regard!
Attention! In any case, please observe the mechanical and thermal
load limits of protective tubes according to DIN 43763 respectively
according to specific S+S standards!
Notes regarding process connection of built-in sensors:
If possible, select material of protective tube to match the material of
piping or tank wall, in which the thermometer will be installed!

Screw-in threads:
Ensure appropriate support of the gasket or sealing material when
mounting! Permissible tightening torque standard values for screw - in
threads, are as follows:
M 18 x 1.5; M 20 x 1.5; pipe thread G ½ " :
M 27 x 2.0; pipe thread G ¾ "
Flange mounting:
In case of flange mounting, screws in the flange part must be equally
tightened. The lateral pressure screw must clamp securely, otherwise
the feeler shaft might slip through.
Welding sleeves:
Specific welding instructions shall be observed.
On principle, unevenness or the like that might influence the system's
"CIP ability" must not develop at welds.
For high-pressure lines, pressure test certifications and inspections
are required.
Notes on commissioning:
This device was calibrated, adjusted and tested under standardised
conditions. When operating under deviating conditions, we recommend
performing an initial manual adjustment on-site during commissioning
and subsequently at regular intervals.
Commissioning is mandatory and may only be performed by qualified
personnel!
