-
-
Check the packing list against the product nameplate.
-
Verify that the order and shipment align with each other and that the shipment is complete.
NOTE: Follow Schneider Electric Conditions of Sale for shortages and errors. -
-
Repackage the Unit Substation for storage if it is not to be installed immediately.
-
Cover all openings to protect against exposure to moisture, dust and contaminants.
-
Leave packing materials intact until the Unit Substation(s) are ready to install.
-
-
Refer to “Conditions of Sale” for details regarding claims for equipment shortages and other errors. Contact your local Schneider Electric distributor for additional assistance.
Handling
Handle Unit Substation carefully to avoid damage. Avoid subjecting the Unit Substation to impact, jolting, jarring and rough handling. Ensure the Unit Substation is transported in the flat position. When possible, transport the Unit Substation to the installation site while still mounted on their shipping pallets. Verify that the weight of the Unit Substation does not exceed the rated capacity of the handling equipment to be used.
Handling with Platform Dollies or Lifts, Pallet Jacks or Fork Trucks
 WARNING |
|---|
|
Tipping hazard unbalanced load
Ensure proper support under heavy end before moving the
equipment.
Failure to follow these instructions can result in death, serious injury, or equipment
damage.
|
Extreme care should be exercised when moving Unit Substation from the bottom.
-
The Unit Substation has an unbalanced weight distribution. Use care to distribute the weight when transporting Unit Substations using platform dollies, platform lifts, pallet jacks or fork trucks.
-
Use hand trucks or forklifts only when the blades or forks are long enough to pass completely under the Unit Substation enclosure or shipping pallet. Wider fork separation is preferred to distribute the weight of the unit evenly for increased stability.
Handling with Cranes: Using Cables Chains or Straps
When lifting the Unit Substation from above, the use of spreader bars with cables or chains is permissible. This will help avoid damage to the enclosure or equipment.
The enclosure can be separated to allow the units to be transported through small openings.
Ensure that the lifting cable pull angles are not less than 60
degrees from horizontal. See Single Point lifting for Enclosures MPZ-A, MPZ-AA, MPU-A,
MPU-AA, MPZ-B, MPZ-BB, MPU-B and MPU-BB and Two-Point Lift for Enclosures MPZ-C, MPZ-CC, MPU-C and
MPU-CC Cable Pull Angles (Not Less than 60 Degrees from Horizontal).
Storing
Leave the packing material that encloses the Unit Substation in place until the unit is ready for its final placement and wiring. This will help to protect the Unit Substation enclosure and internal parts from dirt, water, moisture contamination and physical damage during storage. Provide extra measures to protect the Unit Substation when the original packing material cannot be retained.
Store Unit Substation(s) indoors in a clean, dry, and heated building with uniform temperatures and adequate air circulation. If necessary, install electric heating to maintain a uniform temperature above the ambient temperature to prevent condensation.
Protect the Unit Substation(s) from weather and contamination when it is not possible to store the Unit Substation(s) indoors.
Before energizing the Unit Substation, complete the steps in Pre-commissioning / Pre-energizing Checks and Testing along with the following steps:
-
Test the insulation resistance if storage in a controlled environment was not feasible.
-
Dry the unit if test levels are unacceptable:
