#   Issue   Reason   Troubleshooting  
1   Fan   won’t   AC   Input   is   1.   Make   sure   the   AC   input   wire   has   a   good  
run,   and   no   abnormal   connection  and  the  plugs  are  connected  firmly  
12V  output   2.  Make  sure  the  mains  power  is  working  well  and  its  
voltage  is  above  100V.  
2   The   fan   is   1.   Voltage   in   1.   Please   check   whether   the   voltage   is   above   100V

6. Precautions  for  Use  

1.   Before   using   the   PSU,   please   ensure   that   the   voltage   and   power   outputs   are  
compatible  with  your  equipment.  
2.   Please   ensure   that   the   PSU   appears   to   be   in   good   shape   and   has   not   suffered  
damage  in  transit.  If  the  exterior  of  the  PSU  appears  damaged,  do  not  use  it.  
3.   Make   sure   that   the   metal   cover   for   the   PSU   with   on/off   switch   is   properly  
grounded.  Improper  grounding  is  dangerous.  
4.   The   PSU   must   be   installed   in   such   a   way   that   it   receives   good,   unobstructed  
airflow.  Under  no  circumstances  should  the  PSU  be  installed  in  an  enclosed  place.  
5.   When   installing   the   PSU,   please   double   check   that   the   output   polarities   are   the  
correct  way  round,  and  that  the  screws  are  fastened  securely  in  place.  
6.  Do  not  attempt  maintenance  on  any  wiring  while  the  PSU  is  powered  up  from  the  
mains.  
7.   Running   the   PSU   at   <80%   load   or   below   can   greatly   prolong   the   life   of   the   PSU.  
Usually,  for  every  10ºC  above  the  rated  amount,  the  life  of  the  PSU  is  cut  in  half.
