INSTALLATION AND MAINTENANCE

SAFETY FIRST

High voltage and rotating parts can cause serious injury or loss of life. Safe installation, operation and
maintenance must be performed by qualified personnel. Familiarization with and adherence to NEMA MG2,
the National Electrical Code, and local codes is recommended. It is important to observe safety precautions
to protect personnel from possible injury. Personnel should be instructed to:

1. Disconnect all power to motor and accessories prior to initiating any maintenance
or repairs.

2. Avoid contact with rotating parts.

3. Act with care in accordance with this manual's prescribed procedures in handling and
installing this equipment.

4. Be sure unit and accessories are electrically grounded and proper electrical installa­tion wiring and controls are used in accordance with local and national electrical
codes. Refer to "National Electrical Code Handbook" - NFPA No. 70. Employ
qualified electricians.

5. Be sure equipment is properly enclosed to prevent access by children or other
unauthorized personnel in order to prevent possible accidents.

6. Be sure shaft key is fully captive before unit is energized.

7. Provide proper safeguards for personnel against rotating parts and applications in­volving high inertia loads which can cause overspeed.

8. Avoid extended exposure to equipment with high noise levels.

9. Observe good safety habits at all times and use care to avoid injury to yourself or
damage to your equipment.

10. Be familiar with the equipment and read all instructions thoroughly before installing
or working on equipment.

11. Observe all special instructions attached to the equipment. Remove shipping
fixtures if so equipped.

12. Check motor and driven equipment for proper rotation and phase sequence prior to
coupling. Also check if a unidirectional motor is supplied and note proper rotation.

13. Do not apply power factor correction capacitors to motors rated for operation
with variable frequently drives. Serious damage to the drive will result if capacitors
are placed between the motor and drive. Consult your drive supplier for more
information.

INSTALLATION AND MAINTENANCE

I. SHIPMENT

Prior to shipment, all Titan-II Motors undergo extensive electrical and mechanical testing, and are thoroughly
inspected. Upon receipt of the motor, carefully inspect the unit for any signs of damage that may have occurred
during shipment. Should such damage be evident, unpack the motor at once in the presence of a claims adjuster
and immediately report all damage and breakage to the transportation company and U.S Electrical Motors.

When contacting U.S Electrical Motors concerning the motor, be sure to include the complete motor identification
number, frame and type which appears on the nameplate (see installation record in this manual).

II. HANDLING

The equipment needed to handle the motor includes a hoist and spreader bar arrangement of sufficient strength
to lift the motor safely. The spreader bar arrangement should always be employed whenever multiple lifting lugs
or eyebolts are provided (See Figures 1A & 1B). The spreader bar should have the lifting hooks positioned to equal
the span of the eyebolts or lifting lugs. The eyebolts or lifting lugs provided are intended to lift the motor weight only.
See Table 6 for motor weights.

Shipment &

Handling

CAUTION

Lifting the motor by means other than specifically noted may result in damage to the
motor or injury to personnel. Note that the eyebolt on the top of WPII enclosure is intended
for lifting the tophat only.

III. STORAGE

1. When to put a Motor in Storage.

If a motor is not put into immediate service (one month or less), or if it is taken out of service for a prolonged
period, special storage precautions should be taken to prevent damage. The following schedule is recommended
as a guide to determine storage needs.

(A) Out of service or in storage less than one month - no special precautions except that space heaters, if

(B) Out of service or in storage for more than one but less than six months - store per Items 2 A through 2F,

(C) Out of service or in storage for six months or more - all recommendations.

2. Storage Preparation.

(A) Where possible, motors should be stored indoors in a clean, dry area.

Storage

supplied, must be energized at any time the motor is not running.

2H, 3 and 4.

(B) When indoor storage is not possible, the motors must be covered with a tarpaulin. This cover should

extend to the ground. Do not tightly wrap the motor as this will restrict air flow and result in surface
condensation. Care must also be taken to protect the motor from flood damage or from any harmful
chemical vapors.

(C) Whether indoors or out, the area of storage should be free from excessive vibration which can cause

bearing damage.

(D) Precautions should be taken to prevent rodents, snakes, birds, or other small animals from nesting

inside the motors. In areas where they are prevalent, precautions must also be taken to prevent insects,
such as mud dauber wasps, from gaining access to the interior of the motor.

(E) Inspect the rust preventative coating on all external machined surfaces, including shaft extensions. If

necessary, recoat the surfaces with a rust preventative material such as Rust Veto No. 342 (manufactured
by E. F. Houghton Co.) or an equivalent. The condition of the coating should be checked periodically and
surfaces recoated as needed.

(F) To prevent moisture accumulation, some form of heating must be utilized to prevent condensation. This

heating should maintain the winding temperature at a minimum of 5°C above ambient. If space heaters
are supplied, they should be energized. If none are available, single phase or "trickle" heating may be
utilized by energizing one phase of the motor winding with a low voltage. Request the required voltage
and transformer capacity from U.S. Electrical Motors. A third option is to use an auxiliary heat source
to keep the winding warm by either convection or blowing warm air into the motor.

(G) Bearing cavities must be completely filled with lubricant during long term storage. Remove the drain

plug and fill cavity with grease at the grease inlet until it begins to purge from the drain hole then replace
the drain plug. Refer to Section XI "Lubrication" for recommended greases. At approximately 2 month
intervals, a small quantity of grease should be injected into grease fitting with drain plug removed.
Exiting grease should be inspected for moisture and contamination. If moisture or contamination is
present, the motor bearings should be inspected and fresh grease installed.
