Receiving and Handling Acceptance
Thoroughly inspect this equipment before accepting shipment from
the transportation company. If any of the goods called for in the bill of
lading or express receipt are damaged or the quantity is short, do not
accept them until the freight or express agent makes an appropriate
notation on your freight bill or express receipt. If any concealed loss
or damage is discovered later, notify your freight or express agent at
once and request him to make an inspection. We are willing to assist
you in collecting claims for loss or damage in shipment; however, this
willingness on our part does not remove the transportation company's
responsibility in reimbursing you for collection of claims or
replacement of material. Claims for loss or damage in shipment must
not be deducted from the invoice, nor should payment of the invoice
be withheld awaiting adjustment of such claims, as the carrier
guarantees safe delivery.
If considerable damage has been incurred and the situation is urgent,
contact the nearest Allen-Bradley Sales Office for assistance. Please
keep a written record of all such communications.
Storage Conditions - Short Term
Following are requirements for storage:
1. Motors must be kept in their original containers (or with
equivalent protection). In addition, they must be stored in a
warehouse free from extremes in temperature, humidity and
corrosive atmosphere.
2. If unusual vibrations exist at the storage location, the motor
should be protected with isolation pads.
3. All breathers and drains are to be operable while in storage and/or
the moisture drain plugs should be removed. The motors must be
stored so the drain is at the lowest point.
Storage Preparation
Improper storage of electric machines will result in seriously reduced
reliability of that equipment.
For example, the following items can occur to an electric motor that
does not experience regular usage while exposed to normally humid
atmospheric conditions:
• Bearings may rust.
• Rust particles from surrounding surfaces may contaminate the
bearings.
• The electrical insulation may absorb an excessive amount of
moisture leading to the motor winding failing to ground.
