1.2.1 Handling Considerations
The Liebert STS2/PDU is bolted to a wood shipping pallet to allow handling by forklift or a pallet jack.
Check the unit size and weight. Refer to the cabinet drawings furnished with the unit for size and weight. Typical
cabinet dimensions are shown in Figures 7 through 22. Typical unit crated weights are:
Plan the route. Review the route over which the unit will be transported to its installation location to ensure that
all passages are large enough to accommodate the unit and support the weight.
Check for any non-negotiable corners or offsets in hallways. Before moving the unit to the intended location,
review 2.0 - Location Considerations.
1.2.2 Unit Preparation
The unit can be removed from the pallet before it is moved to its location.
Complete the following steps to properly remove the Liebert STS2/PDU from the shipping pallet:
1. Set the pallet in a level area with enough room to maneuver and remove the unit.
2. Remove the bolts holding the unit to the shipping pallet (located in the base of the unit).
3. Remove the shipping blocks from under the frame of the unit.
4. Use a forklift to raise the unit off the pallet and onto the floor. On the 250A unit ensure that the forklift is clear of the unit's
casters and stabilizing feet. Lift the unit from the rear.
5. Conduct an internal inspection of the unit. See the list in 1.3 - Internal Inspection.
1.3 Internal Inspection
After the Liebert STS2/PDU has been unpacked, conduct an internal inspection:
1. Verify that all items have been received.
2. If spare parts were ordered, verify their arrival.
3. After the Liebert STS2/PDU has been removed from the pallet, open the door and remove cabinet panels to check for
shipping damage to internal components.
4. Check for loose connections or unsecured components in the cabinet(s).
5. Check for any unsafe condition that may be a potential safety hazard.
After the Liebert STS2/PDU has been inspected and no problems are found, the unit can be moved to its
installation location. If using a forklift, remember to lift the unit from the rear.
WARNING
Risk of heavy unit falling over. Can cause equipment damage, injury or death.
Exercise extreme care when handling Liebert STS2/PDU cabinets to avoid equipment damage or injury to
personnel.
The cabinet can be safely tilted 15 degrees in any direction by forklift. If moving the unit up a ramp on its
casters (if the unit is so equipped) or a pallet jack, ensure that the incline does not exceed 15 degrees.
Locate the center of gravity symbols and determine the unit’s weight before handling the cabinet.
