Integrated Battery Rack
Purpose
This document provides instructions for initial assembly and
installation of the OutBack Integrated Battery Rack (IBR).
Scope
Installation Instructions
This document applies to
the three-shelf IBR-3-48-175, depicts OutBack EnergyCell RE
batteries. Figure 2, the two-shelf IBR-2-48-175, depicts
OutBack EnergyCell GH batteries. If other batteries are
used, they must be 12 Vdc batteries which also meet the
following requirements:
AGM valve-regulated lead-acid recombinant type
Maximum discharge 100 cc/hr per battery
Maximum discharging temperature 160°F (60°C)

Alternately, ½” bolts can be inserted through the mounting holes
into prepared openings.

10. Install the protective shields on the left and right sides of the battery
rack. Each shield has an edge which is designed to slide into a metal
e rack. (See below.) Once the edge of the shield is secured,
the other side can be attached using M6 screws. (See the illustration

the use of a battery monitor such as the
DC. Perform the following steps before step 5 on page 2.
Remove the negative bus bar and cables from the left side of the rack (see right).
Unbolt the individual cables from the bus bar.
Three pairs of holes are located in the area where the bus bar is mounted (below,
left). A shunt can be placed over each set of holes. Each shunt has twin screws
(below, center) which can be used for mounting.
Reinstall the negative bus bar so that it mounts across the inner terminal of each
shunt (below, right). Each negative battery cable must not be bolted to the bus bar,
but should connect to the outer terminal of each shunt. However, the load cable
must connect to the negative bus bar.
The battery monitor’s voltage sensing wires must connect to the bus bars (positive
and negative), not the batteries.
