2.2.1 Handling Considerations
The static switch is bolted to a wooden shipping pallet to allow handling by forklift equipment or a
pallet jack.
Easily Moved — The unit is furnished with integral castors that allow the unit to be rolled into place
after it has reached its location and is removed from the pallet.
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 5 through 7. Typical unit weights are:
Plan the route — Review the route over which the unit will be transported to its installation loca-
tion 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 3.0 - Location Considerations.
2.2.2 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 from the shipping pal-
let:
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. Ensure that the forklift is clear of
the unit’s casters and leveling feet. Lift the unit from the rear.
5. Conduct an internal inspection of the unit. See the list below of inspection items.
2.3 Internal Inspections
After the Liebert STS2 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 Static Transfer Switch2 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 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.
