A contact rail is provided including a module coupling end and a mating end. A diode mounting surface is positioned between the module coupling end and the mating end. A pivot member extends from a base of the module coupling end. The pivot member is configured to be engaged by an elongated tool. A module coupling fastener engages the base of the module coupling end. The elongated tool is configured to engage the module coupling fastener. The elongated tool is configured to pivot about the pivot member to separate the module coupling fastener from the base of the module coupling end so that a contact from a power module is receivable between the base of the module coupling end and the module coupling fastener.
