INTRODUCTION:
This instruction book covers the CD180AT-CD500AT line of DC motors and generators.
II. RECEIVING:
The equipment should be placed under adequate cover immediately upon receipt as packing coverings are NOT
suitable for out-of-doors or unprotected storage. Standard factory packing methods do not allow for stacking of motors.
Each shipment should be carefully examined upon arrival. Any damage should be reported promptly to the carrier
and to the nearest office of GE Industrial Systems. Shipping damage is not covered under the standard warranty. A claim must be filed with the carrier.
A. Storage
During installation or when in storage, the machine and its parts must be protected from the following:
1. Dirt of all kinds.
2. Wetness and temperature extremes.
Protection from dirt can be achieved by covering the machine with a tarpaulin or polyethylene sheet or keeping it
where the surrounding area is clean.
