Vertiv™ NetSure™ Supervision Module for Distribution Unit Plus Installation and User Manual
1 Introduction
1.1 Overview
This assembly consists of a Vertiv™ NetSure™ SM-DU+ enclosed in a sheet metal housing. This assembly is used in applications
where the NetSure™ SM-DU+ is mounted external to a power system equipped with an NCU controller. The NetSure™ SM-DU+
assembly is used to connect load shunts and fuse alarm signals to the NCU controller. The NetSure™ SM-DU+ assembly provides
twenty-five (25) load shunt monitoring inputs and fourteen (14) fuse alarm monitoring inputs.
The NetSure™ SM-DU+ assembly connects into the NCU CAN bus. Up to eight (8) NetSure™ SM-DU+ assemblies can be connected
to an NCU. Refer to Figure 1.1 for an illustration of the NetSure™ SM-DU+ assembly.
