Rack ad Panel  
The Ultra 5 rack mount unit is a standard 10HP plug in unit, for a standard 
84HP (19”), 160 mm sub rack unit.  
The backplane that is supplied with the rack unit should first be fitted to the 
back of the sub rack, so that when the rack unit is inserted into the rack it 
connects correctly. 
To install the unit into the sub rack, slide the Ultra 5 into the rack and secure 
by tightening the four captivated screws that are in the faceplate. 
The panel mount unit should be installed by cutting a hole of size DIN 68
+0.7
 
x 138
+1.0
 mm in the panel, then insert the Ultra 5 enclosure through the hole, 
and tighten the fixing screws from the rear. Make sure you leave sufficient 
room for the cables behind the enclosure (a depth of at least 225 mm behind 
the panel should suffice). 
All electronic products are susceptible to electrostatic 
shock, so follow proper grounding procedures during 
installation. 
Dimensions of the rack enclosure are as shown below:
