6.4 Preparation for use 
 
 
 

From  the  mains  lines  conductor  to  the  case  of  the  unit  there  is  a  high 
leakage current. 
The mains lines conductor is connected to ground via high value capacitors 
due to the measurement system to be applied. 

 

 

 
Over current protection is not provided in the LISN. The LISN must be 
connected  to  a  power  mains  which  has  the  properly  rated  mains 
protection installed. 
 

 

 

 
The leakage currents between the phases and the earth line generally 
exceed  permitted  limits  for  typical  environments  due  to  internal 
capacitors;  for  this  reason  it  is  mandatory  to  use  a  current  rated 
insulating transformer to supply the PMM LISN Network. 
 

 

 

 

PMM LISN Network, the insulating transformer and Equipment Under 
Test  must  be  provided  by  an  appropriate  current  rated  contact 
breaker or fuses as closest as possible on the supply line and with a 
safety indication of equipment operated by. 

 

6.5 Pilot circuit 
 
 
 
 

 

According to EN 60309 (IEC 309) Normative, the industrial mains plugs and 
outlets, with an operating current, are provided with an auxiliary connector 
called Pilot Circuit contact. 
 

The  Pilot  Circuit  contact  is  used  to  avoid  mains  plug  disconnection 
with an operating high current load connected. In this case a current 
rated  remote  control  switch  shall  be  provided  to  allow  a  safe 
automatic mains disconnection. 
The  Pilot  Circuit  contact  and  the  remote  control  switch,  connected 
according  to  the  following  figure  example,  also  allows  to  check 
automatically the protection earth conductor continuity till the Device 
Under Test mains connection.

 Pilot Circuit connection example 

 
 
 
 

 

 

This  is  a  Safety  Class  I  equipment,  it  is  provided  with  a  protective 
earth  terminal.  Before  connecting  this  instrument,  ensure  that  an 
uninterruptible  safety  earth  ground  is  provided  from  the  main  power 
source  to  the  product  protective  earth  connection.  If  this  instrument 
is  to  be  connected  to  other  equipment  or  accessories,  prior  to 
energizing  either  unit  verify  that  a  common  ground  exists  between 
them.  Any  interruption  or  loosening  of  the  protective  earth  ground 
conductor,  either  inside  or  outside  the  unit  or  in  an  extension  cable 
will  cause  a  potential  shock  hazard  that  could  result  in  personal 
injury. Verify the safety earth ground functionality before operation.
