Installing adapter brackets onto a Shasta 5000
Install adaptor brackets onto a Shasta 5000 to prepare it for mounting onto the
NEBS 2000 frame.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• You need adapter brackets with the following part numbers, from the
hardware kit NTHW85:
— P0914659, left adapter bracket
— P0914660, right adapter bracket
Procedure steps
1 Hold the left bracket so that
a. it is vertical and two columns of holes face you
b. the label TOP faces you and is at the top
c. the wider spaced holes are at the left side
2 While facing the front of the Shasta 5000 (at the open cavity), position the
surface of the bracket that is facing you against the rear of the left
mounting ear on the Shasta 5000. For orientation, see the figure
“Location of shelf hardware for a Shasta 5000 in a NEBS 2000 frame”
(page 573).
3 The column of narrower holes are intended to fasten to the mounting ear.
Align the bottom mounting ear hole with the left hole second from the
bottom on the adapter bracket. A portion of each adapter bracket extends
above the Shasta 5000 shelf.
4 Fasten the bracket to the mounting ear using 4 thread-forming 10-mm
(3/8-in.) hex-head screws from the kit NTHW85. Thread the screws from
the front towards the rear.
5 Tighten all screws to snug plus a 1/4-turn. Avoid stripping by over-
tightening.
6 Repeat step 1 to step 5 for the right adapter bracket. Ensure the column
of wider holes is at the right side and not attached to the mounting ears of
the shelf.
