Explanation of symbols used in the manual:

- This symbol denotes especially important guidelines concerning the installation and  
operation of the device. Not complying with the guidelines denoted by this symbol  
may cause an accident, damage or equipment destruction.

IF THE DEVICE IS NOT USED ACCORDING TO THE MANUAL THE USER IS  

RESPONSIBLE FOR POSSIBLE DAMAGES.

- This symbol denotes especially important characteristics of the unit.
  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.

- If the device is equipped with PE connector, it should be connected to PE wire. 

Otherwise PE wire should be connected to GND connector.

-  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.
