Relay Interface Module

An optional Relay Interface Module (RIM) uses relay contact closures to indicate
the operating status and alarm condition of the UPS system. A maximum of two
monitoring accessories (RMPs, RIMs, or SCMs) can be installed. See Table 1 for
the number of accessories permitted. Figure 21 shows the RIM with its four 15-pin
connectors labeled J1 through J4.
The RIM can provide these signals:
·
UPS AVAILABLE
·
UPS OFF LINE
·
UTILITY FAILURE
·
BATTERY WEAK
