Additional Information 

Electromagnetic Precautions

 

Logitech

 

have  designed  in  a  great  deal  of  noise  immunity  into  the  product  in  accordance  with 

EN5001-2 and EN5002-2 (radiated emissions, conducted emissions, ESD, radiated susceptibility and 
fast burst transient testing)  

However it is still vital to use good EMC (Electromagnetic Compatibility) techniques on installation of 
both  this  and  other  associated  electronic  equipment  and  sensors  in  order  to  ensure  reliable 
operation. 

It is important to note that if used with systems that radiate high levels of harmonic noise such as DC 
Drives, AC  Inverters  and  Servo  Drives  then  the  levels  of  imposed  interference  can  greatly  exceed 
that of the European Standards.   

In such cases it is important to ensure that mains leads are routed as far as possible from all cables 
carrying power to such equipment and that the supply should, if viable, be taken from a clean source.   

Where this is not possible, it is advisable to use a good quality mains filter mounted as close to the 
instrument as possible, ensuring that the cable between the filter and the instrument is kept separate 
from any cables carrying high levels of current or any fast switching transients. 

All  signal  connections  to  the  instrument  should  be  made  using  screened  lead  with  the  screen 
connected to mains earth at one end only.   

Wherever possible, it is advisable to connect the 0V terminal to mains earth, unless it is found that 
the mains earth is of poor quality or when it is essential that the signal input is floating — see 

Mains 

Earth 

on page 7. 

Low Voltage Directive

 

It is essential that the mains supply to the instrument is fused externally to no more than 1A and that 
the cabling supplying power to the instrument is rated for at least 3A.   

Low voltage signal cables should not be run in the same conduit or twisted or tied to cables carrying 
voltages in excess of 50V (AC or DC). 

If the instrument is not installed fully in accordance with the instructions in this User Guide it may not 
comply with the requirements of the Low Voltage Directive.
