6-2-3  Prevention of foreign matter entry 
 
Treat the cabinet with the following items. 
  Make sure that the cable inlet is dust and oil proof by 
using packing, etc. 
  Make sure that the external air does not enter inside 
through heat radiating holes, etc. 
  Close all clearances of the cabinet. 
  Securely install door packing. 
  If there is a rear cover, always apply packing. 
  Oil will tend to accumulate on the top. Take special 
measures such as oil-proofing packing so that oil does 
not enter the cabinet from the screw holes. 
  After installing each unit, avoid machining in the 
periphery. If cutting chips, etc., stick onto the 
electronic parts, trouble may occur. 
  When using the unit in an area with toxic gases or high 
levels of dust, protect the unit with air purging (system 
to blow clean air so that the panel's inner pressure is 
higher than the outer pressure).
