Unpacking and Storage
Moving the Generator
Improper lift rigging can allow unit to tumble causing injury and damage.
Do not use the engine lifting eyes to remove the engine and generator together.
Unpack the equipment with care in order to avoid scratching painted surfaces. Move the unit to the mounting location. The unit can be moved by either of the following methods:
Attach an overhead crane to the eyebolts that are installed on the generator frame.
Use a lift truck in order to lift the generator. The hoist and the hoist cables should have a rating that is greater than the weight of the generator. When the unit is moved, ensure that the generator is completely supported by the lift truck's fork tines. Also ensure that the generator is balanced on the lift truck's fork tines. Slide the fork tines beneath the attached skid in order to lift the generator. Storage
Short Time Storage
If the generator is not installed immediately, store the generator in a clean area. This area should also have the following conditions: low humidity, stable humidity and stable temperature. Space heaters must be energized in order to keep condensation from the windings. All accessory equipment that is supplied with the unit should be stored with the generator. The combined unit should be covered with a durable cover in order to protect against the following contaminants:
Dust
Dirt
Moisture
Other airborne abrasive materialLong Time Storage
A storage period in excess of six months should be preceded by the following preparation:
Install desiccant bags inside the exciter's cover and install desiccant bags inside the screen of the fan.
Seal the unit in a covering of plastic or other material that has been designed for that purpose.
Adequately tag the generator. This will ensure that preservative greases and desiccant bags are removed before the unit is placed in operation. Bearing Inspection
Ball bearing generators use grease. This grease is subject to deterioration. If the generator is stored longer than one year, new ball bearings should be installed. These bearings should be greased to the proper level prior to being put into operation. If inspection indicates that bearings are free of rust or corrosion, and no noise or excessive vibration appear on start-up, replacement is not necessary. Location
The location of the generator must comply with all local regulations. The location of the generator must also comply with all special industrial regulations. Locate the generator in an area that meets the following requirements:
Clean
Dry
Well ventilated
Easily accessible for inspection and maintenanceAccess to the radiator filler cap is on the roof of the enclosure. There must be safe access to the roof of the enclosure. There must be sufficient clearance above the roof of the enclosure.Do not obstruct air inlet openings. Do not obstruct discharge openings. Air flow must reach these openings. If the generator is exposed to harsh environmental conditions, the generator can be modified in the field in order to add filters and space heaters. In addition, a more rigid periodic maintenance schedule should be established.Electrical Measurements
Measure the insulation resistance of each winding if the generator was exposed to the following conditions:
Rapid changes in temperature
Freezing
Wet climate during shipment
Wet climate during storageNote: These tests should be conducted prior to any power connections that are being made. These tests should be conducted prior to any control connections that are being made.Refer to this Operation and Maintenance Manual, "Rotating Rectifier - Test" in order to measure the following items:
Exciter field (stator)
Exciter armature (rotor)
Generator field (rotor)
Generator armature (stator)Protective Devices
The output to the load of the generator should always be protected with an overload protection device such as a circuit breaker or fuses. Fuses should be sized by using the lowest possible current rating. However, this rating must be above the current rating for full load. A common recommendation is 115 percent of rated current. Determine the size of fuses or determine the size of circuit breakers in accordance with NEMA, IEC, and Local Electrical Codes.
