An optional RIM II uses relay contact closures to indicate the operating status and
alarm condition of the UPS system. The module uses a serial interface line and may
support up to eight critical loads. The RIM II can be flush‐mounted or
surface‐mounted on a desktop, or secured to a wall. Figure 8‐4 shows the RIM II with
its four 15‐pin connectors labeled J1 through J4.
The RIM II can provide the status and alarm signals shown in Table 8‐2.
