20. Isolation Resistance 

  Use  DC  isolation  tester  (MAX  500V)  between  output 
and  baseplate.  Isolation  resistance  value  is  100M

Ω

  and 

above  at  500VDC  applied  voltage.  Also  take  note  that 
depending  on  the  isolation  tester  used,  some  testers 
generate high voltage pulse. Discharge the power module 
after test using a resistor, etc.

    CE MARKING 

CE Marking, when applied to a product or packing 
material  for  a  product  covered  by  this  handbook, 
indicates  compliance  with  the  Low  Voltage 
Directive and RoHS Directive. 

 

UKCA MARKING 
UKCA  Marking,  when  applied  to  a  product  or 
packing  material  for  a  product  covered  by  this 
handbook,  indicates  compliance  with  the  Electrical 
Equipment  (Safety)  Regulations  and  Restriction  of 
the  Use  of  Certain  Hazardous  Substances  in 
Electrical & Electronic Equipment Regulations.
