Safety Procedures

This equipment contains hazardous voltages. Death, serious personal injury or property damage can result if safety instructions are not followed.

The successful and safe operation of motors and generators is dependent upon proper handling, installation, operation and maintenance, as well as upon proper design and manufacture. Failure to follow certain fundamental installation and maintenance requirements may lead to personal injury and the failure and loss of the motor as well as damage to other property.

Only qualified personnel should work on or around this equipment after becoming thoroughly familiar with all warnings, safety notices and maintenance procedures contained herein. Only qualified personnel should be involved in the inspection, maintenance and repair procedure and all plant safety procedures must be observed.

Qualified Person: For the purpose of this manual and product labels, a Qualified person is one who is familiar with the installation, construction and operation of the equipment, and the hazards involved. In addition, he or she has the following qualifications:

a. Is trained and authorized to energize, de-energize,

clear, ground and tag circuits and equipment in accordance with established safety practices.

b. Is trained in the proper care and use of protective

equipment, such as rubber gloves, hard hat, safety glasses, face shields, flash clothing, etc., in accordance with established safety practices.

c. Is trained in rendering first aid.

Danger: For the purpose of this manual and product labels, Danger indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.

Warning: For the purpose of this manual and product labels, Warning indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury.

Caution: For the purpose of this manual and product labels, Caution indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It is also used to alert against unsafe practices.

Motors should be installed and grounded per local and national codes.

Do not operate this equipment in excess of the values given on nameplate or contrary to the instructions contained in this manual. The equipment (or a prototype) has been factory tested and found satisfactory for the condition for which it was sold. Operating in excess of these conditions can cause stresses and strains beyond design limitations. Failure to heed this warning may result in equipment damage and possible personal injury.

DANGER

Hazardous voltage.

Will cause death, serious injury, electrocution or property damage.

Disconnect all power before working on this equipment.

NOTE

Squirrel cage induction machines can be driven by various types of prime movers. These will act as induction generators. This instruction manual applies to both motors and induction generators. However, for clarity reasons, the machine will be referred to as a “motor”.

Introduction

The purpose of this booklet is to offer some short, easy to follow recommendations to our customers, users and distributors for the care of electric motors in storage.

For practical purposes, such equipment is considered to be in storage not only when it is in the storeroom but also when;

1. It has been delivered to the jobsite and is awaiting installation, or

2. It has been installed but regular operation is delayed pending completion of plant construction, or

3. There are long idle periods between operating cycles, or

4. The plant or department is shut down.

NOTE

Recommended brand products have shown good performance. Siemens Energy & Automation, Inc. however, cannot assume responsibility or be liable for products other than those it warrants.

Manufacturers or distributors of products are:

Tectyl 502-C and 506 Valvoline Oil Co. Div. of Ashland Oil and Refining Co. 150 Fourth Avenue Freedom, PA 15042

P.D. George Insulation Manufacturers Corp. 1231 Superior Avenue, N.E. Cleveland OH 44114

Indoor Storage (Up to 5 Years)

NOTE

Rodents and other animals in search of warm surroundings or food, like to house inside motors. Some of them attack the insulation materials. Their access to the motor should be prevented.

Wholly Controlled Atmosphere

Requirements

Uniform temperature between 40°F (4.5°C) and 140°F (60°C) throughout the room maintained at least 10°F (5.5°C) above the dew point. Relative humidity of 50% or less. Dust accumulation should be minimal with no harmful fumes and no ambient vibration.

Partially Controlled Atmosphere

Requirements

The room selected should be as clean and dry as possible with no ambient vibration.

If the ambient temperature exceeds 140 °F (60°C), the space or structure should be enclosed but ventilated. If the ambient temperature is below 40 °F (4.5 °C), the space heaters, if the motor is so equipped, should be energized. The enclosing structure should be designed to protect the motor from flying debris or other damage from high winds.

If the motor can be moved, it is suggested that the entire motor be encased in a strong, transparent plastic bag. Before sealing the bag, a moisture indicator should be attached to the side of the motor and several bags of silica gel desiccant placed inside the bag around the motor. When the moisture indicator shows that the desiccant has lost its effectiveness, as by a change in color, the bag should be opened and the desiccant replaced with fresh material. Take care in placing the bags of desiccant so that none is in contact with the heater element.

When a motor cannot be sealed for effective use of a desiccant, and the relative humidity is greater than 50% or where there are large daily swings in temperature, proper storage requires that the space heaters (anticondensation heaters) be energized. Heaters supplied in the motor are sized to raise the windings temperature 10°F to 15°F (5.5°C to 8°C). This prevents moisture from condensing on the windings. If the motors are not equipped with space heaters, consult the factory for proper size of external heaters to be used.
