18、repared by a technical committee of the NEMA Industrial Control and Systems Section. It 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 medium voltage fire pump

19、controllers. It is intended to be used by specifiers, purchasers, installers, and owners of medium voltage fire pump 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 Subcommit

20、tee on Fire Pump Control. It was written as a service in response to the many questions from the user public, specifiers, and inspection authorities regarding medium voltage fire pump controller installations. The intent is to pursue excellence in design, manufacture, and service of products made by

21、 NEMA member companies. It has been developed through continuing consultation among manufacturers, users, and national engineering 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 insta

22、llation guide is necessarily confined to providing recommendations for a successful installation. When equipment conforming with these recommendations is properly selected and is installed in accordance with NFPA 70 National Electrical Code and NFPA 20 Standard for the Installation of Stationary Pum

23、ps for Fire Protection and properly maintained, the hazards to persons and property will be reduced. However, since any piece of industrial control equipment can be installed, operated, and maintained in such a manner that hazardous conditions may result, following the recommendation of this guide d

They are revised frequently to reflect user input and to meet changing conditions and technical progress. Users should secure the latest editions. Proposed revisions to this installation guide should be s

26、itate movement, handling, installation, and maintenance of medium voltage fire pump controllers at the job site and to help avoid personal injury and equipment damage during these processes. Information includes the following: a. Handling b. Storage c. Installation of conduits, cables, and wires d.

27、Pre-energization and energization e. Care and maintenance f. Required field marking 1.2 PRECAUTIONS There is a hazard of electric shock or burns to personnel resulting in injury or death whenever they are working on or near electrical equipment. Turn off power supplying this equipment before working

28、 inside the controller and lockout or tag out or both, disconnecting means in accordance with NFPA 70E Standard for Electrical Safety in the Workplace*. Where it is not feasible to de-energize the system, take the following precautions: a. Persons working near exposed parts that are or may be energi

29、zed should be instructed in and should follow the safety practices (including appropriate PPE apparel, equipment, and tools) in accordance with NFPA 70E Standard for Electrical Safety in the Workplace. b. Persons working on exposed parts that are or may be energized should in addition to “a,” be qua

30、lified persons who have been trained to work on energized circuits. Working on energized medium voltage equipment with the door open should be prohibited under any circumstances for safety reasons. c. Field marking in compliance with NEC110.16 Arc-Flash Hazard Warning is required. d. Medium voltage

31、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 considered. 1.3 QUALIFIED PERSONNEL The proper operation of medium voltage medium volta

32、ge 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 or death, the failure or loss of the medium voltage fire pump controller

33、, or any combination thereof and damage to other property. OSHA 29 CFR Part 1910.399 defines a qualified person as “One familiar with the construction and operation of the equipment and the hazards involved.” NFPA 70E Article 100 defines a qualified person as “one who has skills and knowledge relate

34、d to the construction and operation of the electrical equipment and installations and has received safety training on the hazards involved.” References to the National Electrical Code are shown as (NEC) and refer to NFPA 70. Reference to manufacturer, unless otherwise specified, means the medium vol

ICS 15.1-2012 Page 2 Copyright 2013 by the National Electrical Manufacturers Association 1.3.1 Qualified Person For the purpose of this guide, a qualified perso

36、n is one who has skills and knowledge related to the construction and operation of the electrical equipment and installations and has received safety training to recognize and avoid the hazards involved. In addition, he or she has the following qualifications: a. Is trained and authorized to energiz

37、e, 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 or face shields, flash clothing etc. in accordance with established safety p

ICS 15.1- 2012 Page 3 Copyright 2013 by the National Electrical Manufacturers Association Section 2 HANDLING 2.1 HANDLING GUIDELINES The following guidelines are provided to help avoid personal injury and equipment damage during handling and to facilitate moving the medium voltage fire pum

39、p controller at the job site. 2.1.1 Follow the manufacturers handling instructions for the specific equipment. 2.1.2 Handle the controller with care to avoid damage to the components, to the frame, to the enclosure or its finish. 2.1.3 Keep the controller in an upright position unless otherwise spec

40、ifically permitted by the manufacturer. 2.1.4 Know the capabilities of the moving means available to handle the weight of the controller. 2.1.5 When the 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

41、 the medium voltage fire pump controller is to be stored for any length of time prior to installation, restore the packing for protection during that period. Where conditions permit, leave the packing intact until the medium voltage fire pump controller is at its final installation position. If the

42、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 controller secured to the shipping skid to prevent distortion of the frame during moving and to minimize tipping. 2.1.8 Exercise care d

43、uring 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 provide a simple method of moving the controller on one floor level if there is no significant incline. Steady the load to prevent tipping. 2.1.10

44、A fork-lift truck may offer a more convenient method of handling the controller. It may also be used to move the controller between levels. Balance the load carefully and use a safety strap to secure the controller to the fork-lift. Medium voltage fire pump controllers are often top heavy and may be

45、 front-heavy or back-heavy. 2.1.11 When a platform elevator is not available to move the controller between elevations, overhead 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 par

46、t of the controller. 2.1.12 Use spreaders Figure 2-1 to provide the vertical lift or lifting plates and the eyebolts to avoid eyebolt or plate failure or crushing or both, or otherwise damaging the controller frame or its finish. 2.1.12.2 To reduce the stresses on the rigging or spreaders, do not al

47、low the angle between the lifting cables and vertical to exceed 45 degrees Figure 2-1 and Figure 2-2. 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 an

48、y unequal weight distribution of load and to maintain the controller in an upright position. 2.1.12.5 Medium voltage fire pump controllers that contain heavy equipment such as transformers mounted within could be adversely affected by tilting.
