I. INTRODUCTION
This instruction book covers the CD2512AT-CD2813AT line of DC motors and generators.
High voltage and rotating parts can cause serious or fatal injury. The use of
electric machinery, like all other utilization of concentrated power and rotating
equipment, can be hazardous. Installation, operation and maintenance of elec-
tric machinery should be performed by qualified personnel. Familiarization with
NEMA Safety Standard for Construction and Guide for Selection, Installation
and
Use of Integral HP Motors and Generators, National Electrical Code and sound local practices is
recommended.
These instructions do not purport to cover all details or variations in equipment nor to provide for every possible
contingency or hazard to be met in connection with installation, operation and maintenance. Should further infor-
mation be desired or should particular problems arise which are not covered sufficiently for the purchaser’s pur-
poses, the matter should be referred to GE Industrial Systems.
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.
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.
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 in a clean area.
Protection from wetness and temperature extremes includes moisture from the surrounding atmosphere con-
densing onto cooler machine surfaces. This condensation on machine surfaces can result in rusting or corro-
sion and the electrical windings may suffer serious damage.
Where wetness and/or cold conditions are present, the machine and its parts must be protected by a safe reli-
able heating system which, at all times, will keep the machine temperature slightly above that of the sur-
rounding atmosphere. If a space heater is included in the machine, it should be energized.
Smaller machines shipped in paper cartons are protected from condensing-type wetness by the insulating
characteristics of the carton. To avoid sweating where these have been exposed to low temperature for an
extended period, allow the machine and carton to attain room temperature before unpacking.
