  SAFETY RECOMMENDATIONS AND INSTRUCTIONS

 

 
This  product  has  been  designed,  produced  and  tested  in  Italy,  and  it  left  the  factory  in  conditions  fully 
complying  with  the  current  safety  standards.  To  maintain  it  in  safe  conditions  and  ensure  correct  use, 
these general instructions must be fully understood and applied before the product is used. 
 

  When the device must be connected permanently, first provide effective grounding; 

  If  the  device  must  be  connected  to  other  equipment  or  accessories,  make  sure  they  are  all  safely 

grounded; 

  In  case  of  devices  permanently  connected  to  the  power  supply,  and  lacking  any  fuses  or  other 

devices  of  mains  protection,  the  power  line  must  be  equipped  with  adequate  protection 
commensurate to the consumption of all the devices connected to it; 

  In case of connection of the device to the power mains, make sure before connection that the voltage 

selected on the voltage switch and the fuses are adequate for the voltage of the actual mains; 

  Devices in Safety Class I, equipped with connection to the power mains by means of cord and plug, 

can only be plugged into a socket equipped with a ground wire; 

  Any interruption or loosening of the ground wire or of a connecting power cable, inside or outside the 

device, will cause a potential risk for the safety of the personnel; 

  Ground connections must not be interrupted intentionally; 

  To prevent the possible danger of electrocution, do not remove any covers, panels or guards installed 

on the device, and refer only to NARDA Service Centers if maintenance should be necessary; 

  To maintain adequate protection from fire hazards, replace fuses only with others of the same type 

and rating; 

  Follow the safety regulations and any additional instructions in this manual to prevent accidents and 

damages.
