Safety precautions 

6.1. 

Signals of residual risks 

•

  The device DSP LASER has been designed with the aim to eliminate or reduce as most 

as possible any risk for the user; however in case of improper use, conditions of limited 
danger, which cannot be completely eliminated, could occur. Possible residual risks are 
indicated in the following chapters of this manual. 

6.2. 

Precautions 

•

  The operations of installation,  test and maintenance of  DSP LASER must be executed 

only  by  qualified  personnel  who  must  strictly  respect  the  instructions  reported  in  this 
manual. 

6.3. 

Dangers of electrical kind 

•

  Place  the  connection  cables  in  such  a  way  to  avoid  accidental  contacts  with  objects 

which can damage them (hot, sharp, abrasive). 

 

•

  Do not use the device in case of damaged connections cables. 

 

•

  Avoid the connection cables enter in contact with water or wet surfaces. 

 

6.4. 

Prohibitions 

•

 

Connecting other equipment to the power supply of DSP LASER provided by the 
AL modules is forbidden. 

This  operation  could  generate  an  overload  for  the  transformer,  so  compromising  the 
correct operation of it and of the circuits for the emission and the reception of the laser 
beam and, as consequence, the device control functions. 

 

•

 

Opening of the devices 

Given  the  typical  function  of  the  device,  opening  the  TX,  RX  and  AL  containers  and, 
least  of  all,  attempting  repair  operations,  is  forbidden.  The  laser  beam  used  by  this 
device  can  be  dangerous  for  the  sight,  if  exposed.  For  the  repairs,  call  only  Nuova 
Elettronica. 
TX  and  RX  must  be  opened  only  to  connect  the  cables  to  the  relevant  clamps  or  to 
dismount  the  device  which  must  be  sent  to  repair.  In  order  to  execute  this  operation, 
only the rear cover must be removed. 

 

6.5. 

Checks 

•

 

Check the operating voltage of the device before using it. 

The  operating  voltage  has  to  match  the  voltage  of  the  local  power  grid.  The  operating 
voltage  is  indicated  over  the  plate  located  on  the  TX  and  RX  modules  or  on  the  AL 
module, if used. 
The  device  is  not  disconnected  from  the  power  grid  until  the  TX,  RX  and,  if  used,  AL 
modules are physically connected to the electric panel , even if the device looks like off. 
Make sure that, if the ALdc or DSPdc is used, the power is derived from a  power supply 
device classified PELV.
