text: <s>[INST] PowerFlex 40 - Minimum Mounting Clearances - is a wiring duct concidered as an obstable is the wiring duct considered as an obstacle that restrict the air flow?? should I absolutley respect the 4.7 inch clearance even if i'm installing the drives inside a cooled enclosure (A/C) , is there any chart document that can show me what's is the minimum clearance to respect according to the ambiante temperature? if I can guaranty that the temperature inside the enclosure will never increase more that 35celcius degrees, should I respect the 4.7 inches clearance between the PF40 drive and the wiring duct ?? Thank you for your help [/INST] The clearance indicated in the User Manual should be respected (and wiring duct is considered an obstacle to the air flow), to avoid drive failure.... technote 34911 has details on this argument... Hope this helps… - fuzzy logic \\n </s>
