Installation and Programming Guide  27 
Installing Panel 
1.  The Aritech Reliance XR should be located away from damp areas (e.g. bathrooms, 
kitchens), away from sources of heat, dust or interference (e.g. air conditioners, 
washing machines, dryers, refrigerators) and away from external walls. 
2.  The metal enclosure should be installed with the door opening from the top to bottom.  
3.   Guides are cut into the enclosure to hold the 
panel, two on the top and two on the bottom. Two 
plastic brackets are pre-installed on the Aritech Reliance 
XR. Slide the panel into the guides as shown in the 
diagram. The terminal strip should face towards you 
once installed. 
4. A plastic strap is provided to allow the door to form a 
temporary surface to hold light parts. 
Installing Legacy NX Modules 
Inside the enclosure there are several 2-holed insertion 
points. These allows for either vertical or horizontal 
placement of legacy NX modules. Each insertion point has 
a larger hole and a smaller hole. 
1.  The black plastic PCB guides feature a groove to hold 
an expansion module. The end with the half-moon 
protrusion fits into the larger hole. The smaller hole is for 
the screw. 
2.  Place the first black plastic PCB guide in the top 
insertion point, groove facing downward. The half-moon 
protrusion will be in the large hole. It does not require 
force to insert. Insert one of the provided screws into the 
smaller hole (from inside the enclosure) to secure it in 
place. A screwdriver should reach through the groove that 
runs the length of the guide to tighten the screw. The 
second PCB guide should be positioned opposite the first 
(groove facing up) and placed in the lower insertion point, 
using the same procedures described above. Once 
mounted, screw it in securely. 
3.  The NX module should slide freely in the grooves of 
both guides.
