Figure 4-1. Removing the Pallet Skids and Supports – Eaton 93PM UPS
Do not remove or loosen the cabinet mounting or cabinet support bolts until instructed.
4. Loosen, but do not remove, the skid mounting bolts holding the pallet skids to the front and rear supports,
and to the left and right side supports (see Figure 4-1).
5. If a sidecar is attached to the UPS, loosen, but do not remove, the sidecar skid mounting bolts holding the
sidecar pallet skids to the sidecar front and rear supports, and to the left and right supports (see Figure 4-1
and Figure 4-2).
RISK OF INSTABILITY. Turning the jacking bolts unevenly may cause the cabinet to become
unbalanced. To prevent tipping the cabinet, raise and lower the jacking bolts evenly.
CABINET MAY TIP. Raise the UPS no more than 3 mm (1/8") above the floor (just enough to allow
the removal of the pallet skids).
