Inspecting and Unpacking the UPS Cabinets
The cabinet is shipped bolted to a metal and wood pallet (see Figure 3-10 or Figure 3-11) with outer protective
packaging material covering the cabinet.
WARNING
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.
1.
Carefully inspect the outer packaging for evidence of damage during transit.
CAUTION
Do not install a damaged cabinet. Report any damage to the carrier and contact an Eaton service
representative immediately.
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 3-6 or Figure 3-7 for the UPS cabinet center
of gravity measurements).
CAUTION
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.
4.
Remove the protective packaging material from the cabinet and recycle in a responsible manner. Retain
any parts kits packaged with the cabinet.
5.
Inspect the contents for any evidence of physical damage, and compare each item with the Bill of Lading.
If damage has occurred or shortages are evident, contact an Eaton service representative immediately to
determine the extent of the damage and its impact on further installation.
NOTE
Startup and operational checks must be performed by an authorized Eaton
Customer Service Engineer, or the warranty terms specified on page W-1 become
void. This service is offered as part of the sales contract for the UPS. Contact an
Eaton service representative in advance (a minimum two-week notice is required) to
reserve a preferred startup date.
NOTE
For the following step, verify that the forklift or pallet jack is rated to handle the
weight of the cabinet (see Table 3-2 for cabinet weight).
NOTE
While waiting for installation, protect the unpacked cabinet from moisture, dust, and
other harmful contaminants. Failure to store and protect the UPS properly may void
the warranty.
