Now also plug in the Z-zero plate. The black wire goes in the Input#1 terminal and the

white (or green) wire goes into a ground terminal (Gnd; you can use the one on the Input

terminal block or the one on the Output block). The red wire goes to 5+ (it is only used by

the Digitizing Probe).

There is USB cable connector for attaching the USB cable that will connect your PRSalpha

Control Box to your computer. It is a short cable that exits on the right side of the Control

Board. Plug the longer 10ft cable supplied with your ShopBot into this connector and run the

longer cable out of the PRSalpha Control Box through the Roxtec fixture. Do not plug the

USB cable into your computer at this point.

Seal the Cable Entry

When you have attached all the cables in the PRSalpha Control Box, it’s time to put the

gaskets around them and close up the Roxtec fixture.

The Roxtec system is designed to keep dust out of the PRSalpha Control Box. Take a

moment to fit each of the cables into a gasket so that the cables fit snugly and the two

halves of the gasket close well. It may be necessary to run two of the smaller cables

through a single gasket. This also provides an element of strain relief if the cables are

inadvertently pulled.

• The blue and black layers of the gaskets are layered like an onion. Take out the blue

and black layers out one at a time (alternating sides) until cable fits snugly in the

gasket.

• Position each gasket with cable into the fixture. Apply a small amount of the

lubricant on the outside of each gasket so the parts are slightly sticky. When all the

cables are placed, fill in with the rest of the empty gaskets.

• Fit the shim into the top of the 5 gaskets.

• Using a screwdriver, close the pivot to seal the Roxtec.

Ground the ShopBot PRSalpha

The Table of the ShopBot should be grounded to System Ground at the power box that

supplies the PRSalpha Control Box. Attach the grounding wire (14-16 gauge) at a

convenient bolt on the table, making sure to scratch off paint under the bolt.

Remember that your dust collection system should also be grounded to the System Ground.

See alpha Dust Skirt Documentation for details on grounding the alpha Dust Skirt hoses to

the Dust Collection device.
