Inspecting and Unpacking the UPS Cabinets

The cabinet is shipped bolted to a metal and wood pallet (see Figure 3-8 or Figure 3-9) with outer protective
packaging material covering the cabinet.
NOTE
The UPS cabinet is heavy (see Table 3-1). If unpacking and unloading instructions are not closely
followed, the cabinet may tip and cause serious injury.
1. Carefully inspect the outer packaging for evidence of damage during transit.
Do not install a damaged cabinet. Report any damage to the carrier and contact an Eaton service
representative immediately.
NOTE
2. Use a forklift or pallet jack to move the packaged cabinet to the installation site, or as close as possible,
before unpacking. If possible, move the cabinet using the pallet. Insert the forklift or pallet jack forks
between the supports on the bottom of the pallet (see Figure 3-5 or Figure 3-6 for the UPS cabinet center
of gravity measurements).
Do not tilt the UPS cabinet more than 10° from vertical or the cabinet may tip over.
3. Set the pallet on a firm, level surface, allowing a minimum clearance of 3m (10 ft) on each side for
removing the cabinet from the pallet.

Eaton service representative in advance (a minimum two-week notice is required) to
reserve a preferred startup date.
For the following step, verify that the forklift or pallet jack is rated to handle the
weight of the cabinet (see Table 3-1 for cabinet weight).
