3.4 Mounting Conditions
(1) Parts, highly susceptible to dust, are mounted with a high density inside the unit. Always use a
sealed structure for the cabinet, and provide the following treatments.
•
Always plug the cable inlet with packing, etc., to prevent dust and oil from entering.
•
Take care so that outdoor air does not enter the heat dissipation holes, etc.
•
Plug all clearances.
•
Always install door packing.
•
If there is a back lid, always install packing.
•
Oil will easily accumulate at the ceiling, and can enter the cabinet from the screw holes. Always
take special measures such as using oil-preventing packing.

(2) Avoid machining in the area after installing each unit. Cutting chips, etc., could get on the electronic
parts and cause damage.
(3) Design so that the cabinet's internal temperature rise is 10°C or less in respect to the outdoor
temperature, and so that it is within the unit's temperature conditions.
Do not allow conductive foreign matter such as screws or metal chips or combustible
foreign matter such as oil enter the unit.
