INM F892 Rev 1
4 .5 Mounting and Removal of the Power Modules
The Power Modules are secured to the carrier with four screw mountings. There are
four locating connectors (two for each module) on the module carrier along with mating
connectors in the F801 or F802 module. Align the module with the retaining screws
and press onto the connector. Hold it in place while tightening the four retaining
screws. To remove a Power Module, support the module while unscrewing the four
retaining screws at its base. Lift the module off the carrier connector.
Note: Earlier versions of the module carriers do not have locating connectors. Align
using the retaining screws furthest from the module connector and rock onto the
connector.
