Kit
1.1 Kit Description
These instructions provide a step-by-step procedure to field install this kit into Power System Spec. No. 582127200. Installation of this
kit in other equipment should not be attempted.
This kit provides a wire harness to reverse the shunt reference voltage to the SM-DU Shunt Monitoring Module located in the primary
power bay. The SM-DU module mounted in the primary power bay contains connections for the internal load shunts provided in each
power bay (the system can consist of up to three power bays). The SM DU module also provides two (2) additional external shunt
monitoring inputs. When used as shipped, any external shunt needs to be installed in the hot (-48V) bus. Use this kit to connect up
to five (5) external shunts located in the return bus. This requires all internal shunts connected to the SM-DU module to be
disconnected and the associated shunt leads isolated.
1.2 Kit Contents
Table 1.1 lists the items furnished with this kit. Before starting the procedure, check the items furnished against those listed to ensure
that there are no shortages.

1.4 Installation Procedure
THESE INSTRUCTIONS SHOULD BE READ THROUGH COMPLETELY BEFORE INSTALLING THE KIT.
The following is a step-by-step procedure to install the kit. The procedure has been written for ease of use and to minimize the
possibility of contact with potentially hazardous energy. This procedure should be performed in the sequence given, and each step
should be completely read and fully understood before performing that step. Observe all “Important Safety Instructions” presented at
the beginning of this document as this procedure is being performed. As each step of the procedure is completed, the box adjacent
to the respective step should be checked. This will minimize the possibility of inadvertently skipping any steps. If the step is not
required to be performed for your site, also check the box to indicate that it was read.

2SM-DU External Shunt Connections
You just installed wire harness pigtail P/N 559353 that was included in kit P/N 559404. This allows you to connect external shunts
which are located in the return bus to the SM-DU module. The SM-DU module provides five (5) shunt monitoring inputs. Refer to the
following procedure and Figure 2.1 for connections details.
2.1.1 Procedure
DANGER! Observe all “Important Safety Instructions” presented at the beginning of this document.
NOTE! Refer to Figure 2.1 as this procedure is performed.
[ ] 1. Connect up to five (5) external shunts to the SM-DU module. Observe proper polarity. See Figure 2.1.
NOTE! With kit P/N 559404 installed, all shunts connected to the SM-DU module must be located in the return bus.
Connect the plus side of the shunt to the positive shunt input on the SM-DU. Connect the negative side of the shunt to the
negative shunt input on the SM-DU.
[ ] 2. Refer to the ACU+ Instructions (UM1M820BNA) and program the SM-DU module’s shunt inputs.
