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
Table 6---1 for the number of accessories permitted. Figure 7---1 shows the RIM
