Installing a Relay Interface Module
The optional Relay Interface Module (RIM) uses relay contact closures to
indicate the operating status and alarm condition of the UPS 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 C for the number of accessories permitted.
Figure 10 shows the RIM with its four 15-pin connectors labeled J1 through J4.
Drawing 164201261---8 in Appendix A outlines the enclosure dimensions.
