Step
2 Aluminum grounding bars
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.
3 Hang the rack in the
enclosure on the top
screws.
Start all screws in the
bottom of the rack, then
tighten all screws.
4 Carefully place the Power
Supply in the leftmost slot
in the Rack, ensuring that
the connector at the back
seats properly.
Insert a slot screwdriver in
the slots at the top and
bottom of the power supply
cover while pulling
backward to open the
cover.
Fasten the screws
(captured in the face of the
power supply) into the tabs
at top and bottom of the
rack.
