Sierra 951 User Manual

INSTALLATION

The Model 951 enclosure is designated for panel mounting in a 1/8 DIN 

cutout.  The cutout dimensions are shown below. 

To panel mount the 951, perform the following steps:

 

1. Rotate the four pawl screws ( outside screws in each corner)  

 

  several turns counter-clockwise to retract the pawls.  Make sure  

 

  the pawls retract enough to clear the back of the mounting panel.   

 

  The pawls may be retracted to accomodate panel thicknesses  

 

  up to 0.25 inches (6.35mm).

 

2. Insert the instrument into the panel cutout.

 

3. Position the pawls so that their elongated dimension overlaps  

 

  the panel cutout, then tighten the screws.  Do not over-tighten.

 

4. Installation complete.

WIRING
