Unloading the UPS Cabinet from the Pallet
The UPS cabinet is heavy (see Table 3-2). If unpacking and unloading instructions are not closely
followed, the cabinet may tip and cause serious injury.
Do not tilt cabinet more than 10° from vertical.

The UPS cabinet is bolted to a pallet consisting of four metal angle supports secured to two wood supports.
To remove the pallet:
1.
If not already accomplished, use a forklift or pallet jack to move the UPS cabinet to the installation area, or
as close as possible, before unloading from the pallet. Insert the forklift or pallet jack forks between the
supports on the bottom of the pallet (see Figure 3-6 or Figure 3-7 for the UPS cabinet center of gravity
measurements).
2.
Open the front door by lifting the latch from the bottom and turning to the right (counterclockwise) and
swing the door open.
3.
Locate the four 1/2" jacking bolts from the parts kit and install them in the threaded holes in the front and
rear supports as shown in Figure 4-1. Place a floor protector from the parts kit underneath each jacking
bolt, and screw the bolts down against them.
The floor protectors protect the floor from being marred by the jacking bolts.
