Liebert POWER PROTECTION STATIC TRANSFER SWITCH User Manual

A high-quality installation begins on the receiving dock. The STS2 and its packaging should be 

inspected when the unit is delivered. If the packaging is not damaged, unpack the unit and conduct 

an internal inspection before beginning the installation process. This section discusses the inspecting 

and unpacking of the STS2.

1. While the STS2 is still on the truck, inspect the equipment and shipping container(s) for any signs 

of damage or mishandling. Do not attempt to install the system if damage is apparent.

2. Upon receipt and before unpacking, inspect the shipping crate for damage or mishandling. Check 

the Shock-Watch™ indicator. 

• If the indicator is red, note on shipper’s receipt and check for concealed damage. 
• If any damage as a result of shipping is observed, file a damage claim with the shipper within 

24 hours and contact your local Liebert representative or Liebert Global Services at 

1-800-543-2378 to inform them of the damage claim and the condition of the equipment.

3. Locate the bag containing the keys for the front access door. The bag is attached to the cabinet. 
4. Compare the contents of the shipment with the bill of lading. Report any missing items to the 

carrier and to Liebert Global Services immediately. 

5. Check the nameplate on the cabinets to verify that the model numbers correspond with the one 

specified. Record the model numbers and serial numbers in the front of this installation manual. 

A record of this information is necessary should servicing be required.

6. If unit is to be stored before installation, it is recommended to store the unit in a dry environment 

with temperatures in the range of -40°F (-40°C) to 176°F (80°C). Use original packing materials or 

other suitable means to keep the unit clean. When opening the shipping crate, use care not to 

puncture the container with sharp objects.

Most STS2 models are contained in one cabinet. The 800–1000 amp units are contained in two cabi-

nets that are connected together and shipped on one pallet.
Because the weight distribution in the cabinet is uneven, use extreme care during handling and 

transporting.
The unit can be moved by forklift or pallet jack.
See 2.2.2 - Unit Preparation on page 5 for instruction on removing the STS2 from the pallet.

NOTE
Read the entire manual before installing and operating the unit. Upon receipt of the Static 

Risk of unit damage.
When moving the unit by forklift, lift the unit from the rear so as to protect the front panel.
Do not exceed a 15 degree tilt with the forklift.
Also, if you are moving the unit by forklift or pallet jack after it has been removed from the 

pallet, be aware of the location of the casters and leveling feet so as not to damage them.
