Mounting Instructions
Designed to directly mount to Cree 62mm style power modules. Four (4) mounting holes for 4x M4-8, Nylon screws
are provided to secure the board to a bracket or enclosure (0.5 Nm) for additional support.
External wires with spade style connectors (part numbers listed below) should be used to connect the Desat detect
pins (X2 & X3) from the module to the gate drive board.
Connectors (female) that fit Desat blade terminal
Right angle connector: TE Connectivity 61070-1
Straight connector: Molex 19002-0013
