About this manual

Purpose of this manual

This manual provides all the necessary information for installing, operating and maintaining an MPR15 (-48 V/15 A) and MPR25 (-48 V, 25 A) series (NT5C06B/C) Switch Mode Rectifier, 19-inch and 23-inch Power Shelf NT5C10 for embedded and system applications, as well as the NT5C13F( ) Low Voltage Disconnect series.

Safety precautions

This equipment meets CSA 22.0 - 0M1982, CSA C22.2 - 107-1957 and UL1950. High voltages are present inside the unit. Consequently, insulated tools, eye protection and adequate lighting are required when working on the unit. The latest drawings must be used.

This equipment contains a number of discrete and micro-electronic solid state devices subject to permanent damage, caused by electrostatic potentials, when handling and installing unless appropriate precautions are observed.
