Removing a horizontal frame from the pallet
Remove a horizontal NEBS 2000 frame from the shipping pallet after
removing the packaging.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• You need three to four helpers to safely lift the frame off the pallet.
• The frame is not attached to the bottom of the crate or the pallet, and will
slide off if tilted enough.
Procedure steps
1 Slit the plastic wrap open so that it can be taped closed while the frame is
being stored before being anchored to the floor. Be careful not to contact
anything under the plastic, especially wires or cables.
2 Latch any cards inside the shelf that may have become unlatched. Ensure
that you latch each card to the transportation position. Refer to the figures
“Upper transportation pockets for card latches” (page 696) and “Lower
transportation pockets for card latches” (page 697).
3 Cut any straps that fasten the frame to the pallet.
4 Remove the plastic sheet around the frame by cutting it. Do it neatly
without pulling it off. Removing the plastic enables firm grips on the
hardware to tilt it upright.
5 Ensure each levelling foot at the bottom end of the frame is threaded all
the way inwards until it touches the base of the frame. You may need an
8-mm (5/16-in.) allen key to turn the shafts from the inside end. For the
location of the feet, see the figure “Unpacking a horizontal
Passport 15000 or 20000 in a frame” (page 777).
