GE Industrial Solutions AF-650 GP Top & Bottom Cover Duct Kit - Manual

This instruction sheet is for the installation of top and bottom covers for the 4x- and 5x-Frame AF-6
drives. These kits are designed to be used to direct the back-channel airflow in and out the back of the
drive as opposed to in the bottom and out the top of the drive (when the drives are being mounted di-
rectly on a wall or inside a welded enclosure).
Using these kits as described removes 85% of the losses via the back channel using the drive’s main
heat sink fan. The remaining 15% must be removed via the door of the enclosure. (Refer to Note 2 for
air flow requirements.)

Notes:
1. If external duct work is added to the exhaust path of the drive, additional back pressure will be cre-
ated that will reduce the cooling of the drive. The drive must be derated to accommodate the re-
duced cooling. First, the pressure drop must be calculated, then refer to the derating tables located
in the AF-6 High Power Operating Instructions.
2. A doorfan(s) is required on the enclosure to remove the heat losses not contained in the backchan-
nel of the drive. The minimum airflow required (at the maximum rated ambient temperature) for the
43 and 44 frame drives is 391 m
3
/h (230 cfm). The minimum airflow required (at the maximum rated
ambient temperature) for the 52 frame drive is 782 m
3
/h (460 cfm). If additional heat losses are
added within the enclosure a calculation must be made to ensure the proper airflow is provided to
