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. Installation of these devices must only be realized by author-
ized qualified personnel. The technical data and connecting conditions
shown on the device labels and in the mounting and operating instruc-
tions 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 function-
ality. This device must not be used for monitoring applications, which
solely 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 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.
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 subse-
quently at regular intervals.

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 addition, the following points are to be observed:
– Devices must only be connected to safety extra-low voltage and under dead-voltage condition. To avoid damages and errors at 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.
– Extremely high concentrations of VOCs, aggressive cleaning agents or silicone-containing vapours can destroy the sensor element or
reduce its service life drastically.
– A suitable weather and sun protection hood must be used when installed outdoors..
– 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 enclosures 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 regarded!
Manual calibration can then be performed as an option. Make sure that
no harmful substances influence the calibration process and that the
sensor is operated in fresh air.
If the automatic system (automatic balancing of CO2 / VOC measurand)
is activated, a cyclical fresh air supply must be provided, as other-
wise incorrect measurements can occur.
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 technical
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)
Attention! In any case, please observe the mechanical and thermal
load limits of the protective tubes according to DIN 43763 or
according to specific S+S standards!
