Figure 8 Protective Shields (sides and front)
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
tab on the rack. (See below.) Once the edge of the shield is secured,
the other side can be attached using M6 screws. (See the illustration
to the right.)
11. Install the protective shields on the front of each battery shelf. Make
certain to orient the shield correctly. The shield has an opening to
allow access to the circuit breaker for each set of batteries. (See the
illustration to the right.) If the shield is oriented incorrectly, it will
block access to the circuit breaker.

NOTE: The battery rack does not require
additional ventilation.
Provide adequate ventilation for the
room where the battery rack is installed.
7. Connect a ground cable to the battery rack.
The ground terminal is located directly below
the negative bus bar (see right). Make sure to
follow all applicable electrical codes when
grounding the rack.
8. The positive and negative bus bars have multiple
attachment points. The battery cables inside the
rack are already attached (see left). The user
should attach a fourth cable for battery loads (see
right). This load cable should be sized
appropriately. As shown to the right, the load
cable must be routed inside the enclosure using
one of the side openings. To complete the circuit,
the return load cable should connect to the bus
bar on the other side of the rack and also routed
inside the enclosure.
9. After load cables have been routed inside the enclosure, they should exit
using one of the conduit openings. The IBR-3-48-175 has six 2” conduit
knockouts on each side of the rack. The IBR-2-48-175 has four 2” conduit
knockouts on either side of the rack and three on top.
For users of the GS Load Center: The top knockouts are designed to
align with the GSLC cabling for ease of installation.
