Receiving, handling and storage

4.Notify Siemens medium-voltage customer service immediately of any damage, at +1 (800) 347-6659 or

+1 (919) 365-2200 outside the U.S.

5.Arrange for a carrier inspection of the damage immediately.

Important: Do not move the equipment from the place it was set when unloading. Also, do not remove or disturb packaging or wrapping material prior to carrier damage inspection. Equipment must be inspected by carrier prior to handling after receipt. This eliminates loss due to claims by carrier that the equipment was damaged or further damaged on site after unloading.

6.Be sure the equipment is properly protected from any further damage by covering it properly after unloading.

7.If practical, make further inspection for possible concealed damage while the carrier’s inspector is on site. If inspection for concealed damage is not practical at the time the carrier’s inspector is present, it must be done within 15 days of receipt of the equipment. If concealed damage is found, the carrier must again be notified and inspection made prior to taking any corrective action to repair. Also notify Siemens immediately at +1 (800) 347- 6659 or +1 (919) 365-2200 outside the U.S.

8.Obtain the original carrier inspection report and forward it with a copy of the noted delivery receipt to Siemens. Approval must be obtained by Siemens from the carrier before any repair work can be performed.

Before approval can be obtained, Siemens must have the documents referenced in the paragraph above. The carrier inspection report and/or driver’s signature on the delivery receipt does not constitute approval to repair.

Note: Any determination as to whether the equipment was properly loaded or properly prepared by shipper for over-the-road travel cannot be made at the destination. Shipments are not released from the factory without a clear bill of lading. Approved methods are employed for preparation, loading, blocking and tarping of the equipment before it leaves the Siemens factory. If the equipment is received in a damaged condition, this damage to the equipment has to have occurred while en route due to conditions beyond Siemens‘ control. If the procedure outlined above is not followed by the consignee, purchaser or their agent, Siemens cannot be held liable for repairs. Siemens will not be held liable for repairs in any case where repair work was performed prior to authorization from Siemens.

Handling procedure

1.Carefully remove the shipping carton from the circuit breaker. Keep the shipping pallet for later use if the circuit breaker is to be stored prior to its installation.

2.Inspect for concealed damage. Notification to carrier must take place within 15 days to assure prompt claim resolution.

3.Each circuit breaker should be lifted appropriately to avoid crushing the side panels of the circuit breaker, or damaging the primary disconnect assemblies.

Type 38-3AH3 vacuum circuit breakers weigh between 800 and 1,000 lbs (364-455 kg), plus an additional 125 pounds (57 kg) for the pallet and packaging.

4.The palleted circuit breaker can be moved using a properly rated fork-lift vehicle. The pallets are designed for movement by a standard fork-lift vehicle.
