3.5 Back-channel Cooling OverviewA unique back-channel duct passes cooling air over the heat sinks with minimal air passing through the electronics area.There is an IP54/Type 12 seal between the back-channel cooling duct and the electronics area of the VLT® drive. This back-channel cooling allows 90% of the heat losses to be exhausted directly outside the enclosure. This design improvesreliability and prolongs component life by dramatically reducing interior temperatures and contamination of the electroniccomponents. Different back-channel cooling kits are available to redirect the airflow based on individual needs.3.5.1 Airflow for J8 & J9 Enclosures130BG823.10225 mm (8.9 in)225 mm (8.9 in)Illustration 3.6 Standard Airflow Configuration for Enclosures J8 and J9Product Overview and Featur...
