1.2

 

List of safety instructions 

  Proper function of the Tension Measuring Amplifier is only guaranteed with the 

recommended application of the components. In case of other arrangement, heavy 
malfunction can be the result. Therefore, the installation instructions on the 
following pages must be followed strictly. 

  Local installation regulations are to preserve safety of electric equipment. They 

are not taken into consideration by this operating manual. However, they have to 
be followed strictly. 

  Improper handling may damage the fragile electronic equipment! Don’t touch the 

electronic unit! Don’t use rough tools as screwdrivers or pliers! Touch earthed 
metal part to discharge static electricity before touching the electronic unit! 

  Bad earth connection may cause electric shock to persons, malfunction of the total 

system or damage of the electronic unit! It is vital to ensure that proper earth 
connection is done.
