240.2 FLOOR MOUNTING THE CCU
NOTE: U L regulations require the fourth CCU
to always be mounted to the wall and is
to be attached to the other three CCUs.
Mounting of the fourth CCU should be
considered at the beginning to ensure
proper wall spacing for the stack’s
location.

the two screws located on
the top front of the CCU, then, mount the CCU
onto the ESE-32B-1 CCU.
Ensure that the hooks provided on the top rear of
the ESE-32B-1 CCU are fully seated in the open
slots on the bottom rear of the ESE-32E-1 CCU.
Secure them both by using the two screws
removed in step

When the second ESE-32E-1 CCU is installed, it
should be attached in the same manner as the
first ESE-32E-1 CCU.
When the third ESE-32E-1 CCU is installed, it
should be attached in the same manner as the
second ESE-32E-1 CCU.
Using the guide lines for wall mounting, mount
the bracket for the third ESE-32E-1 ETU to the
