  Read any information regarding this symbol carefully

1. 

   BASIC REQUIREMENTS AND USER SAFETY

 

 

-

 The manufacturer is not responsible for any damages caused by 

inappropriate installation, not maintaining the proper environmental 
conditions and using the unit contrary to its assignment.

- 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.

- GND input of device should be connected to PE wire;

- 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 unit malfunction 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  connected  equipment must meet  the appropriate  standards 

and regulations concerning safety and be equipped with adequate overvoltage 

and interference filters.

-

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

has no user serviceable parts. Defective units must be disconnected and 
submitted for repairs at an authorized service centre.

- In order to minimize fire or electric shock hazard, the unit must be protected 

against atmospheric precipitation and excessive humidity.

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

humidity, corrosive gasses and oils.
