Installing a Relay

Interface Module

5.1Installation Procedures

The optional Relay Interface Module (RIM) uses relay contact closures to indicate the operating status and alarm condition of the Parallel Capacity/Redundant system. The module uses an RS422 serial interface line and may support up to eight critical loads. A maximum of two monitoring accessories (RMPs, RIMs, or SCMs) can be installed. Refer to Chapter 4, Table 4---1 for the number of accessories permitted. Figure 5---1 shows the RIM with its four 15-pin connectors labeled J1 through J4. Drawing 164201373---9 in Appendix A outlines the enclosure dimensions.
