Appendix - 
Installation of 
Remote 
Termination Panels 
(RTPs) 
207  The Remote Termination Panel (RTP) provides an easy way to connect the 
HC900 controller to the field wiring.  The RTP integrates some of the typical 
externally connected components, reducing wiring and setup time.  It also 
minimizes the need for multiple wires under a single screw connection by 
expanding the connectivity of the shared terminals of the I/O modules.
