Amphenol connectors are typically used to connect a ShapeArray (SAA) in environments where there is a reasonable chance of water exposure with the connector. They provide a small amount of splash-proofing to ensure a solid connection to the ShapeArray.
In some cases, you may be required to re-wire a ShapeArray's Amphenol connector in the field. This is often the case when the ShapeArray's cabling has been accidentally cut or when the cabling must be routed through small diameter conduit or holes. This guide will help you re-wire the male Amphenol connector. To rewire an Amphenol connector, the following tools are required.
- Cable insulation cutting tool, wire strippers, or wire cutters
- Small flat-headed screwdriver (e.g. 2.5 mm)
- A female Amphenol connector, such as the one on an SAA Field Power Unit (SAAFPU)
Step 1 - Disassemble the Male Amphenol Connector
Remove the cable nut by unscrewing it.
Figure 1: Male Amphenol connector with cable nut unscrewed
Remove the grommet by pulling it out of the connector body.
Figure 2: Male Amphenol connector with cable nut unscrewed and grommet removed
Remove the connector body by unscrewing it.
Figure 3: Attach the male Amphenol connector to an SAA Field Power Unit to make unscrewing the body easier
NOTE: It is much easier to unscrew the connector body if the male Amphenol connector is plugged into a female connector, such as the one available on an SAA Field Power Unit.

Step 2 - Remove Cable Support
Unscrew the clamps in cable support.

Step 3 - Back Off Wire Screws and Remove Connector
Loosen the wire screw for each wire on the connector so that the wires are no longer secured.

Remove the connector.

Step 4 - Strip Cable Insulation and Trim Wires
Remove 51 mm (2”) of insulation from the end of the cable to which the connector will be reattached using a cable insulation cutter, wire stripper, or wire cutter.
Figure 9: (Left) Removing ShapeArray cable insulation with cable insulation cutter and (Right) ShapeArray cable with insulation removed
When using the cable insulation cutter, make only ONE turn around while paying close attention to the depth of the cut. DO NOT cut the insulation on the wires inside the cable. Cut the black, red, white, and blue wires to approximately 16 mm - 19 mm (5/8" – 3/4”) in length.
NOTE: DO NOT trim the shield wire.

Step 5 - Strip Wires and Wrap Ground Wire
Strip approximately 6 – 7 mm (1/4") of insulation from the wires.
Figure 11: Wire stripped, shield wire untouched
Wrap the shield wire around the black wire. Please ensure you twist the shield wire into the stripped portion of the black wire.

Step 6 - Insert Cable into Bottom of Connector
Slide the bottom three pieces of the male Amphenol connector over the cable to which the connector is being reattached.

Step 7 - Connect Wires to Male Connector
Ensure the tightening screws on the male end of the Amphenol connector are loose. With the bottom of the male connector head facing up, insert the following wires:
- White wire – hole 1
- Blue wire – hole 2
- Red wire – hole 3
- Black wire – hole with ground symbol
Figure 14: Locations for inserting the stripped wires from the ShapeArray cable
Place the connector top flush to a flat surface with the cable straight up. While pressing the cable wires into the connector, tighten the screws.
Step 8 - Attach Cable Support
Snap on the cable support to the head of the connector.
Figure 15: Reattaching the cable support to the male Amphenol connector
Attach the metal clamp with screws to the cable support. Ensure you thread the screws into the metal clamp from the opposite side of the cable support; otherwise, they will not tighten.

Step 9 - Complete Bottom Connector Assembly
Slide the bottom three pieces of the connector to the top of the cable. Screw the body onto the connector head.
NOTE: It is much easier to screw the body to the connector if the male Amphenol connector is plugged into a female end, such as the one available on an SAA Field Power Unit.
