SAFETY MANUAL 

Electrical safety 

 

 

PPM0732  pulse  generator  module  is  high  voltage  equipment.  Please  be 
very careful and operate by qualified personnel only. 

 

There  is  a  risk  of  electric  shock,  strong  electromagnetic  interference, 
damage of the generator, or other electronic equipment in case of improper 
use. 

 

It  is  strongly  prohibited  to  switch  on  the  generator  without  an  output 
coaxial cable. We recommend using at least 50 centimeters length coaxial 
cable  connected  between  the  generator  and  the  load  (antenna  or  first 
attenuator) to prevent permanent damage to the generator. There is a risk of 
electrical  arcing  on  the  open  HV  coaxial  connector  and  damage  to  the 
output circuit of the generator.  

 

When adding or removing the generator to or from the system, ensure that 
the  power  supply  is  unplugged  (in  OFF  state).  Please  apply  power  supply 
only after connecting output and input coaxial cables.  

 

Please  provide  sufficient  free  space  and  allow  free  airflow  around  the 
generator  for  good  cooling  in  case  of  long  time  operation  at  a  high 
repetition rate.  

 

Operation safety 

 

 

Please read this manual before installing and using the generator. 

 

Before  using  the  product, make  sure  that all the  cables are applicable  and 
not damaged. High voltage connectors should be clean and dry, free from 
dust, dirt, and any obstacles. 

 

To  avoid  short  circuits,  keep  metal  parts  like  clips,  screws,  and  staples 
away from the generator. 

 

The  generator  is  designed  for  operation  in  normal  laboratory  conditions. 
Avoid  dust,  humidity,  and  temperature  extremes.  Do  not  place  the 
generator in any place where it may become wet.  

 

Place the generator on a stable surface. 

 

If  you  encounter  any  technical  problem  with the  generator,  please  contact 
Megaimpulse Ltd. Do not try to repair the generator by yourself.
