Damaged Pins on D-Type Connector of G120C, G120X and G120CU with BOP-2
Why does the BOP-2 attachment cause damage to the D-Type connector on the inverter?
The BOP-2 fit is a precision connection and any debris and/or wires under the BOP-2 can lead to a misalignment and in turn causes damage to the pin of the connector.
Fig 2 – Illustrate the correct attachment method compared with the incorrect method with a wire trapped under the BOP-2.
Improper removal of BOP-2 unit
Alternatively if the installer is unable to exert the required force to press the clip down then the BOP-2 unit can be removed in an incorrect manner. The BOP-2 can be removed by rotating it in an anti-clockwise direction. Fig 4 below shows how the unit can be removed incorrectly.
Removing the unit as displayed in Fig 4 will lead to deformation of the D sub connector shroud on the G120C unit along with a bent/broken bottom pin.
The damage that can be caused by incorrect attachment and/or removal is shown in the following:
