Further important safety instructions can be found in the
individual chapters of these operating instructions.
2.1 Intended use
The temperature transmitter T24.10 is a congurable transmitter for
use with resistance thermometers (RTD) and resistance sensors.
The temperature transmitter has been designed and built solely for the
intended use described here, and may only be used accordingly.
The technical specications contained in these operating instructions
must be observed. Improper handling or operation of the instrument
outside of its technical specications requires the instrument to be

If the instrument is transported from a cold into a warm environment,
the formation of condensation may result in instrument malfunction.
Before putting it back into operation, wait for the instrument
temperature and the room temperature to equalise.
The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.
2.2 Personnel qualication
WARNING!
Risk of injury if qualication is insucient!
Improper handling can result in considerable injury and

WARNING!
Protection from electrostatic discharge (ESD) required.
The proper use of grounded work surfaces and personal
wrist straps is required when working with exposed
circuitry (printed circuit boards), in order to prevent static
discharge from damaging sensitive electronic components.
To ensure safe working on the instrument, the operating
company must ensure
■
that suitable rst-aid equipment is available and aid is
provided whenever required,
■
that the operating personnel are regularly instructed
in all topics regarding work safety, rst aid and
environmental protection and knows the operating
instructions and, in particular, the safety instructions
contained therein.
DANGER!
Danger of death caused by electric current
Upon contact with live parts, there is a direct danger of
death.
■
Electrical instruments may only be installed and
connected by skilled electrical personnel.
■
Operation using a defective power supply unit (e.g.
short circuit from the mains voltage to the output
voltage) can result in life-threatening voltages at the
instrument!
WARNING!
Residual media in dismounted instruments can result in
a risk to persons, the environment and equipment.Take
sucient precautionary measures.
