Rack Installation - Mount Racks
Step
Aluminum grounding bars
2
for I/O module wiring are
optional. They can be
mounted at top, at bottom,
or at top and bottom of the
rack, as indicated at right.
If grounding bars are
included, attach them with
two M3 screws (supplied
with grounding bars in
plastic bag).
Note: The plastic bag also
includes four M4 screws
for attaching the grounding
wire lugs, which are
attached later.
Attach the M4 screws
loosely to the grounding
bars for safe keeping.
Hang the rack in the
3
enclosure on the top
screws.
Start all screws in the
bottom of the rack, then
tighten all screws.
Note: You may find it
easier to postpone this
step until after all
components have been
installed in the rack.
Repeat for each rack in
4
your system.
