1.3 Installation, startup and operation
General hazards and warnings
This device is intended for permanent installation with a fixed electrical connection. The installation, connection
to the electricity supply, startup and maintenance must be carried out by trained, qualified personnel who are
authorised to perform this type of work. The respective specialist personnel must have read and understood this
installation and operation manual, and follow the instructions contained therein. The operator must ensure that
the measuring system is wired correctly in accordance with the wiring diagrams. Contact protection is deactivated
when the cover is removed (risk of electric shock). The housing may only be opened by qualified personnel.
Disconnect the power supply prior to electrical installation, and ensure that it cannot be reconnected
without your consent.
Pay attention to the following points during installation:
• Voltage, operating data
• Maximum transmission length
• Cable cross-section and length
• Ambient temperature and installation position
1.4 Technical progress
We reserve the right to modify the technical specifications without prior notice.
WARNING!
Danger of electrocution!
Touching or gripping live electrical parts can cause an electric shock, which may
result in burns, paralysis or death.
• The device should only be opened, installed or repaired when the power has
been switched off.
• Only specialist technicians are authorised to work on or with mains voltage.
They must comply with the applicable regulations.
• Only the intended terminals should be used to connect the device to the mains

2 Structure of a measuring point
A complete measuring point for thermal energy consists of the CALEC®ST II energy calculator, paired temperature
sensors and flow sensor.
The applicable regulations and recommendations for installation and operation must also be complied with,
e.g. Section 6 of EN 1434, and the recommendations of professional associations such as the „Merkblätter der
Fernwärmeversorgung“ [fact sheets for district heating] issued by the German Energy Efficiency Association for
District Heating, Cooling and CHP (AGFW). The installation of control immersion sleeves is mandatory in some
countries (e.g. in France after FDE 39-007).
NOTE!
Type of temperature sensor, pulse value, installation side!
Check whether the temperature sensor type (e.g. Pt100), pulse value and installation
side (cold, hot) of the flow sensor match the nameplate on the CALEC®ST II.
NOTE!
Calibrated device!
Depending on the version, the CALEC®ST II is a calibrated measuring device
(see calibration markings on the nameplate).
Calibration is rendered invalid if any changes are made to the calibration parameters.
The parameters can only be accessed once the verification seal has been destroyed.
Parameters related to the calibration of calibrated devices can only be adjusted by
the manufacturer or by a designated calibration centre. The commissioning of a calibrated
measuring point must be made by an authorized organisation according to the valid regu-
lations.
After commissioning of the meter, the components (the calculator, the flow meter and two
temperature sensors) must be sealed.

3 Scope of delivery,
installation accessories
The supplied assembly and connection accessories
are located on the top of the housing:
The yellow piercing awl 1) can be used to pass the
cables through the membrane seals easily
The strain on the wire can be eased using the
white strain-relieving discs 2).
The two red plugs 3) are used to secure the two screws in the front cover.
Unauthorised opening of the device can be detected if these safety caps have been installed.
Removing the protective caps:
Pierce with a sharp tool and lever them out. This damages the cap, which needs to be replaced.
NOTE!
Calibrated device!
The unit can be damaged if not stored correctly!
This precision measuring device can be damaged by heat, moisture, dirt and vibration,
which can cause malfunctions.
The device must be stored in accordance with the specifications and only removed from
the packaging immediately prior to installation.
