2. Use a forklift or other material handling equipment to move the cabinets to a
convenient unpacking area. Insert the forklift jacks between the foam cushions
on the bottom of the unit.
CAUTION:
DO NOT tilt cabinets more than 10 degrees from vertical.
3. Set each pallet on a firm, level surface, allowing a minimum clearance of
4.6m (15 ft) on each side for removing the cabinets from the pallets.
4. Cut the steel bands around each cabinet.
5. Remove the protective cardboard covering from the cabinets, cutting where
indicated, using a knife blade no longer than 25 mm (1 in.).
NOTE: Do not discard the packaging material yet. Instructions for unloading the
cabinet from the pallet are printed on the cardboard, and you will need to
refer to them.
6. Remove the plastic bag and foam packing material, and discard or recycle
them in a responsible manner.
Unloading the UPS System From the Pallet
The UPS and Environmental cabinets are each bolted to sheet metal pallets
consisting of four supports secured to foam cushions. The foam cushions act as
shock absorbers for the cabinet during shipment.
WARNING:
UPS cabinets are extremely heavy. If unloading instructions are not closely
followed, the cabinet may tip and cause serious injury.
Turning the jacking bolts unevenly may cause the cabinet to become
unbalanced. To prevent tipping, raise and lower the jacking bolts evenly. The
cabinet should only be raised approximately 3 mm ( 1/8 in.) above the floor
(just enough to remove foam cushions).
1. Starting with the UPS cabinet, open and remove the cabinet door. Remove the
retaining screw located inside the door at the bottom hinge pivot point, then lift
the door off. Save the retaining screws for reinstallation of the door.
2. Locate the field kit (packed inside of the cabinet or communication panel).
Locate the four ½-in. jacking bolts and install them in the threaded holes in the
front and rear supports. Place a floor protector underneath each jacking bolt,
and screw the bolts down against them. The floor protectors will save the floor
from being marred by the jacking bolts.
3. Loosen, but do not remove the hardware holding the foam cushions to the
front and rear supports (labeled “1” in Figure 3).
4. Turn each jacking bolt consecutively, two full turns, until the foam cushions
clear the floor by approximately 3 mm ( 1/8 in.).
5. After the foam cushions clear the floor, remove the hardware loosened in
step 3. Pull the foam cushions out from under the cabinet, and discard or
recycle them in a responsible manner.
