7 Install the upper and lower mounting fixtures.
Place the upper mounting fixture on the top covers of the existing and expansion racks, and
temporarily secure it with M12 hexagon bolts.
Note: Confirm that the height of the expansion rack is aligned with that of the existing rack.
If not, adjust the height with the leveling feet.
Be careful when working at height on the top cover. Never put your foot on the rack
because it is very dangerous.
If the shield rubber protrudes from the racks or goes inside a rack when the expansion
rack is aligned with the existing rack, adjust it by pulling it out or pushing it inside with
your fingers.
Using the M6 core spring nuts installed on the front and rear H frames of the racks in steps 3
and 5, secure the lower mounting fixture with M6 flat head screws.
Fully tighten the M12 hexagon bolts that were temporarily tightened in the upper mounting
fixture.
Note: Be careful when working at height on the top cover. Never put your foot on the rack
because it is very dangerous.
