3 Mount the 24VDC Power Connector-Receptacle

Clip off the cap

Slide the connector-receptacle tail through the CB first from outside of the bottom hole

Tighten nut by hand first, then by nylon wrench

Pull the 6Pos terminal block outside of the control box to have more room for tightening the nut

4 Final routing of CB power harness

Connect the 2 yellow wires from the receptacle to the TB Pos-1 & 3, then install the 50 mm yellow jumper between Pos 3 & 5

Lay out the wire harnesses with the wires laying flat against the CB as shown

Hot glue in the four locations as shown, if you don't have hot glue, electrical tape can be substituted instead

Install Rambo with 4x M3x5 SHCS as shown
