Section 2: Installation of rejection
bracket kit
Proceed with the following three steps:
Step 1: From Table 1 determine the number and location of stop
nuts (B), washers (D), and hex bolts (C) to be used. All parts are
not required for all assemblies. Insert bolts and lock washers into
the appropriate holes in the rejection bracket (A), and assemble stop
nuts from the other side. Torque to 8–10 ft-lbs (10.5–13 Nm).

ote:N The stop nut arrangement shown here is for reference purposes only,
and is not a valid configuration.
Step 2: Assemble the bracket assembly to the floor of the cassette
as shown using two M6 x 10 mm thread-forming crimptite screws
(E). Torque to 8–10 ft-lbs (10.5–13 Nm).
If the cassette is for use with an IZM32 breaker up to 3200A, or an
IZM97 breaker with a rating of 4000A, the installation is complete.
If the cassette is for use with an IZM40 or IZM63/IZM99 breaker,
proceed to Step 3.
Figure 3. Step 2
Step 3: On cassettes for use with an IZM40 or IZM63/IZM99
breaker, install two identical rejection bracket assemblies as shown
in Step 1 and Step 2.
