Action
A connector removal tool is available to allow removal of the AMP Faston
receptacles. This tool allows removal of these receptacles from the power
input and output connectors of the MSP modules. This tool comes in two
lengths: P0746192 152 mm (6 in.) and P0747552 254 mm (10 in.). You can
use the shorter tool when conditions cause limited access to the rear of the
MSP. An example of limited access is MSP modules located behind the
cabinet bulkhead.
This tool is approximately 2 mm (.090 in.) thick and 17 mm (.65 in.) wide,
with a jaw-like cut-out at each end. The cut-out profile conforms to the shape
of the Faston receptacle. The shorter tip of each profile positions the receptacle
in the tool.
The first meeting point of the tool serves as the pivot point. When you rotate
the tool around this pivot point, you engage a profile tip with the action-arm of
the power connector. This profile tip is the longer tip of the profile that has a
hook on the end of the tip. As you press the action-arm of the connector, you
disengage the receptacle from the connector tab. To remove the receptacle,
pull the tool with the receptacle trapped in the jaw of the tool away from the
connector. To disengage the tool from the receptacle, rotate the hook of the
tool off the action-arm of the receptacle.
The shape of the cut-out is the same on each end of the tool. The position of
the profile is off by 15 degrees. This difference allows for the use of the tool
at different angles. You can require the use of the tool at different angles
because of limited access to the connectors.
