Using Features and Options

11.4 Relay Interface Module

An optional RIM uses relay contact closures to indicate the operating status and alarm condition of the UPS system. The RIM can be flush-mounted or surface-mounted on a desktop, or secured to a wall. Only one system monitoring device (RMP, RIM, or Supervisory Contact Module) can be installed (see Table 11-1). Figure 11-2 shows the RIM with its four 15-pin connectors labeled J1 through J4.
