Installing the Interconnection Box (IB)

The following information is for general reference and is not intended to replace recommended National Electric
Code (NEC) procedures. It is important for the installer to understand that electrical equipment and wiring located
in Class I, Division 1 and 2 installations shall comply with the latest appropriate articles found in the National
Electric Code (NFPA 70) and other applicable code requirements.
1. The physical dimensions of the Interconnection Box (IB) are shown in Figure 21. The IB is installed in the
truck's cab either under the seat, mounted on the wall inside the cab, mounted to the passenger side of the
"dog house" in cab-over trucks, or mounted to a custom-made bracket that can also support the optional
printer. Use four, 3/16" (4 mm) bolts to mount the IB to the mounting surface. In the event of limited access,
the front cover of the IB can be completely removed rather than swung open, by removing four #15 Torx
screws. Put the excess coils of cable under the seat or clamp them to the IB mounting stand.
2. Table 7 and Figure 22 show IB Power Side terminal wiring connections. Use Power Side knockouts (left side
of IB) for all cables attaching to this terminal block.
