ST-72CP NEMA 4X COMPACT WALL MOUNT FIBERGLASS 
ENCLOSURE 

The ST-72CP shown in Figure 6-3 is a fiberglass NEMA 4X wall mount enclosure. One, 16 
channel I/O option PCB’s, such as analog input or relays, may be mounted inside this 
enclosure making it ideal for Modbus or wireless applications.  It is suitable for 
mounting outdoors but an above mounted weather deflector shield is recommended.  
Weight is approximately 17 pounds.  Figure 6-4 provides important warning information 
concerning correct grounding procedures for non-metallic enclosures. Conduit entries 
are not provided so installers may place entries as needed.  Bottom or lower side areas 
are recommended.  Care must be taken to avoid drilling into circuit boards mounted 
inside the enclosure.  Properly ground the enclosure and follow national and local 
electrical codes.
