Powerware 5075 kVA operation manual Supervisory Contact Module, Shutdown Imminent

Supervisory Contact Module

An optional Supervisory Contact Module (SCM) establishes an interface between the UPS manufacturer’s equipment and the customer’s monitor. This interface allows the customer to monitor operational status of the UPS equipment. A maximum of two monitoring accessories (RMPs, RIMs, or SCMs) can be installed. See Table 1 for the number of accessories permitted. Figure 39 shows the SCM, input connections on TB1, and output connections on TB2.
