12. Characteristics of the External Power Supply CAUTION IMPROPER GALVANIC ISOLATION The power components are not galvanically isolated They are intended for use only in systems designed to provide SELV isolation between the supply inputs or outputs and the load devices or system power bus You must use SELV rated supplies to provide 24 VDC source power to the NIM Failure to follow these instructions can result in injury or equipment damage The external power supply needs to deliver 24 VDC source power to the island The supply that you select can have a low range limit of 19 2 VDC and a high range limit of 30 VDC The external supply must be rated safety extra low voltage SELV rated The SELV rating means that in addition to basic insulation between hazardous voltages and the DC output a second supplementary insulation layer has been added As a result if a single component insulation does not perform the DC output does not exceed SELV limits Calculating the Wattage Requirement The amount of power see page 41 that the external power supply must deliver is a function of the number of modules and the number of built in power supplies installed on the island The external supply needs to provide 13 W of power for the NIM and 13 W for each additional STB power supply like an STB XBE 1300 BOS module For example a system with one NIM in the primary segment and one BOS module in an extension segment would req
