User manual for - TEMPERATURE TRANSDUCER TRS-02a 

1. 

       BASIC REQUIREMENTS AND USER SAFETY

 

 

-

 The manufacturer is not responsible for any damages caused by 

inappropriate installation, not maintaining the proper technical condition 
and using the unit against its destination.

- Installation should be conducted by qualified personnel . During installation all 

available safety requirements should be considered. The fitter is responsible for 

executing the installation according to this manual, local safety and EMC 

regulations.

- The unit must be properly set-up, according to the application. Incorrect 

configuration can cause defective operation, which can lead to unit damage or 

an accident. 

If in the case of a defect of unit operation there is a risk of a serious threat 

to the safety of people or property additional, independent systems and 
solutions to prevent such a threat must be used.

-  

The unit uses dangerous voltage that can cause a lethal accident. The unit 

must be switched off and disconnected from the power supply prior to 
starting installation of troubleshooting (in the case of malfunction).

- Neighbouring and mating equipment must meet the requirements of appropriate 

standards and regulations concerning safety and be equipped with adequate 

anti-overvoltage and anti-interference filters.

-

 Do not attempt to disassemble, repair or modify the unit yourself. The unit 

has no user serviceable parts. Units, in which a defect was stated must be 
disconnected and submitted for repairs at an authorized service centre.

- Do not use the unit in areas threatened with excessive shocks, vibrations, 

corrosive gasses and oils.

- Do not use the unit in explosion hazard areas.

- Do not use the unit in areas with significant temperature variations, exposed to 

icing.

- Do not use the unit in areas exposed to direct sunlight. 

- Make sure that the ambient temperature (e.g. inside the control box) does not 

exceed the recommended values. In such cases forced cooling of the unit must 

be considered (e.g. by using a ventilator).

The unit is designed for operation in an industrial environment and must 
not be used in a household environment or similar.
