3.

Gently slide the End Cap out of the HPX base assembly.

3. Insert the Dual USB Module into the HPX Base

Orient the module relative to the HPX base assembly so that the Module’s 
faceplate is facing up, towards the mounting surface (FIG. 6). 

2.

 Align the Mounting Notches on the module with the Mounting Rails on the HPX 
base.

Note: Module faceplates are notched in a “tongue and groove" type fashion to ensure 
that all modules are oriented correctly in the HPX. Note the orientation of the notched 
faceplate on each module before sliding the module(s) into the HPX assembly.

3.

Slide the module into position.

4.

Install any remaining modules into the HPX base.

4. Re-Install the End-Cap

Caution: Do not use a high-powered torque screw driver. Over-tightening these 
screws can damage the product.

1.

Align the Mounting Notches on the End Cap with the Mounting Rails on the HPX 
base.

2.

Slide the End Cap into the HPX base until it is fully inserted against the end of 
the base assembly.

3.

Secure the End Cap with the six (black) sheet metal screws (removed in 
Step 2 - 2; see FIG. 5).

4.

Replace the (silver) pivot screw and pivot pawl assembly (removed in Step 2 - 1, 
see FIG. 5) in the center of the End Cap.

5. Mount the HPX into the Mounting Surface

Caution: Do not use a high-powered torque screw driver. Over-tightening these

Tighten the four mounting screws (loosened in Step 1, see FIG. 4) located inside 
and at each end of the HPX base assembly, to rotate the retaining tabs into 
locking position under the mounting surface.

3.

Replace any cable ties that were removed in Step 1.
