Install so that the front of the interface unit is visible and the terminal block comes to the bottom.

5-2-3 Prevention of entering of foreign matter

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 by using head radiating holes, etc.
• Close all clearances.
• 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 the top so that
oil does not enter the cabinet from the screw holds.
• After installing each unit, avoid machining in the periphery. If cutting chips, etc., stick onto the
electronic parts, trouble may occur.
