I
18、t was approved in accordance with the bylaws of NEMA. This installation guide provides practical information concerning the general technical considerations in the installation of electric fire pump controllers. It is intended to be used by specifiers, purchasers, installers, and owners of fire pump
19、 controllers. This installation guide represents the result of many years of research, investigation, and experience by the members of the NEMA Industrial Control and Systems Subcommittee on Fire Pump Control. It was written as a service in response to the many questions from the user public, specif
20、iers, and inspection authorities regarding fire pump controller installations. The intent is to pursue excellence in design, manufacture, and service of products made by NEMA member companies. It has been developed through continuing consultation among manufacturers, users, and national engineering
21、societies. It is not intended to instruct the user of fire pump control equipment except insofar as to provide recommendations and some installation guidance. This installation guide is necessarily confined to providing recommendations for a successful installation. When equipment conforming with th
22、ese recommendations is properly selected and is installed in accordance with the National Electrical Code (NFPA 70) and the Standard for the Installation of Centrifugal Fire Pumps (NFPA 20) and properly maintained, the hazards to persons and property will be reduced. However, since any piece of indu
23、strial control equipment can be installed, operated, and maintained in such a manner that hazardous conditions may result, following the recommendation of this guide does not by itself assure a safe installation. NEMA publications are subject to periodic review. They are revised frequently to reflec
24、t user input and to meet changing conditions and technical progress. Users should secure the latest editions. Proposed revisions to this installation guide should be submitted to: Vice President, Engineering Department National Electrical Manufacturers Association 1300 North 17th Street, Suite 1752

27、el whenever they are working on or near electrical equipment. Turn off power supplying this equipment before working inside the controller and lockout or tag out or both, disconnecting means in accordance with NFPA 70 E, Part II*. Where it is not feasible to de-energize the system, take the followin
28、g precautions: a) Persons working near exposed parts that are or may be energized should be instructed and should use practices (including appropriate apparel, equipment, and tools) in accordance with NFPA 70 E, Part II b) Persons working on exposed parts that are or may be energized should, in addi
29、tion to a), be qualified persons who have been trained to work on energized circuits Fire pump controllers may have two sources of power supply, as well as alarm and auxiliary circuits energized from remote power supplies. When de-energizing the controller for servicing these power sources must be c
30、onsidered. 1.3 QUALIFIED PERSONNEL The proper operation of fire pump controllers is dependent upon handling, installation, operation, and maintenance by qualified personnel. Failure to follow certain fundamental installation and maintenance requirements could lead to personal injury, the failure or
31、loss of the fire pump controller, or any combination thereof, and damage to other property. References to the National Electrical Code are shown as (NEC) and refer to NFPA Publication No. 70.

ICS 15-2011 Page 2 Copyright 2011 by the National Electrical Manufacturers Association Section 2 HANDLING 2.1 HANDLING GUIDELINES The following guide
35、lines are provided to help avoid personal injury and equipment damage during handling and to facilitate moving the fire pump controller at the job site. 2.1.1 Follow the manufacturers handling instructions for the specific equipment. 2.1.2 Handle the fire pump controller with care to avoid damage to
36、 the components, to the frame, to the enclosure or its finish. 2.1.3 Keep the fire pump controller in an upright position unless otherwise specifically permitted by the manufacturer. 2.1.4 Know the capabilities of the moving means available to handle the weight of the fire pump controller. 2.1.5 Whe
37、n the fire pump controller is received, unpack it sufficiently to inspect for concealed damage and to determine that the shipment is complete and correct. 2.1.6 If the fire pump controller is to be stored for any length of time prior to installation, restore the packing for protection during that pe
38、riod. Where conditions permit, leave the packing intact until the fire pump controller is at its final installation position. If the packing is removed, cover the top and openings of the controller during the construction period to protect it against dust and debris (see Section 3). 2.1.7 Keep the f
39、ire pump controller secured to the shipping skid to prevent distortion of the frame during moving and to minimize tipping. 2.1.8 Exercise care during any movement and placement operations to prevent falling or unintentional rolling or tipping. 2.1.9 Rod or pipe rollers with the aid of pinch bars pro
40、vide a simple method of moving the fire pump controller on one floor level if there is no significant incline. Steady the load to prevent tipping. 2.1.10 A fork-lift truck may offer a more convenient method of handling the fire pump controller. It may also be used to move the fire pump controller be
41、tween levels. Balance the load carefully and use a safety strap to secure the fire pump controller to the fork-lift. Fire pump controllers are often top heavy and may be front-heavy or back-heavy. 2.1.11 When a platform elevator is not available to move the fire pump controller between elevations, o
42、verhead hoisting may be used. Lifting plates and eye bolts (Figure 2-1) or channels, angles or bars with lift holes (Figure 2-2) may have been provided as a permanent or removable part of the fire pump controller. 2.1.12 Use spreaders (Figure 2-1) to provide the vertical lift or lifting plates and t
43、he eyebolts to avoid eyebolt or plate failure or crushing or both, or otherwise damaging the fire pump controller frame or its finish. 2.1.12.2 To reduce the stresses on the rigging or spreaders, do not allow the angle between the lifting cables and vertical to exceed 45 degrees (Figures 2-1 and 2-2
44、). 2.1.12.3 Use slings with safety hooks or shackles. Do not pass ropes or cables through the lift holes in bars, angles, or channels. 2.1.12.4 Select or adjust the rigging lengths to compensate for any unequal weight distribution of load and to maintain the fire pump controller in an upright positi
45、on. 2.1.12.5 Electric fire pump controllers that contain heavy equipment such as transformers mounted within could be adversely affected by tilting.

46、ufacturers Association Section 3 STORAGE 3.1 An indoor fire pump controller that is not installed and energized immediately should be stored in a clean, dry space where a uniform temperature prevents condensation. Preferably, it should be stored in a heated building with adequate air circulation and
47、 protected from dirt and water. Fire pump controllers should be stored where they are not subject to mechanical damage or corrosive atmosphere. 3.2 An indoor fire pump controller that must be stored outdoors should be securely covered for protection from weather conditions and dirt. Temporary electr
48、ical heating should be installed to prevent condensation; approximately 150 watts per controller section is adequate for the average fire pump controller size and environment. All loose packing or flammable materials should be removed before energizing space heaters. 3.3 An unenergized outdoor fire
49、pump controller should be kept dry internally by installing temporary heating (see 3.2), or by energizing self-contained space heater(s).
