SAFETY INSTRUCTIONS AND WARNINGS FOR ELECTRICAL POWER EQUIPMENT

G ELECTRIC SHOCK can kill. Do not touch live electrical parts.

ELECTRIC ARC FLASH can injure eyes, burn skin, cause equipment damage, and ignite combustible material. Do not use power cables to break load and be sure tools don't cause short circuits.

IMPROPER PHASE CONNECTION, PARALLELING, OR USE can damage this and attached equipment.

IMPORTANT: - Protect yourself and others. Read and understand all the instructions in this Operating/Instruction Manual before installing, operating, or servicing this equipment. Keep this manual available for future use by all operators.

A. GENERAL Equipment that supplies electrical power can cause serious injury or death, or damage to other equipment or property, if the operator does not strictly observe all safety rules and take precautionary actions. Safe practices have developed from past experience in the use of power source equipment. Certain of the practices below apply to engine driven equipment.

B. SHOCK PREVENTION Bare conductors, or terminals in the output circuit, or ungrounded, electrically-live equipment can fatally shock a person. Have a competent electrician verify that the equipment is adequately grounded and learn what terminals and parts are electrically HOT. Use proper safety clothing, procedures, and test equipment.

The electrical resistance of the body is decreased when wet, thus more easily permitting dangerous currents to flow through it. When inspecting or servicing equipment, do not work in damp areas without being extremely careful. Stand on dry rubber mat or dry wood, use insulating gloves that are effective when dampness or sweat cannot be avoided. Keep your clothing dry and never work alone.

1. Installation and Grounding of Electrically Powered Equipment -Electrical equipment must be installed and maintained in accordance with the National Electrical Code, ANSI/NFPA 70, and other applicable codes. A power disconnect switch or circuit breaker must be located at the equipment. Check the nameplate for voltage, frequency, and phase requirements. If only 3-phase power is available, connect any single-phase rated equipment to only two wires of the 3-phase line. DO NOT CONNECT the equipment grounding conductor (lead) to the third live wire of the 3-phase line, as this makes the equipment frame ---- electrically HOT, which can cause a fatal shock.

HOBART BROTHERS COMPANY TROY, OHIO OPERATION AND MAINTENANCE MANUAL

WITH ILLUSTRATED PARTS LIST POWER DISTRIBUTION BOXES

OM-457

Be sure to connect the grounding lead, if supplied in a power line cable, to the grounded switch box or building ground. If not provided, use a separate grounding lead. Be certain that the current (amperage) capacity of the grounding lead will be adequate for the worst fault current situa- tion. Refer to the National Electrical Code ANSIJNFPA 70 for details. Do not remove plug ground prongs. Use correct mating receptacles.

2. Output Cables and Terminals - Inspect cables often for damage to the insulation and the connectors. Replace or repair cracked or worn cables immediately. Do not overload cables. Do not touch output terminal which equipment is energized.

3. Service and Maintenance - This equipment must be maintained in good, electrical and mechanical condition to avoid hazards stemming from dis- repair. Report any equipment defect or safey hazard to your supervisor and discontinue use of the equipment until its safety has been assured. Re- pairs should be made by qualified personnel only. Shut OFF all power at the disconnecting switch or line breaker before inspecting or servicing the equipment. Lock switch OPEN (or remove line fuses) so that power cannot be turned ON accidentally. Disconnect power to equipment if it is out of service. If troubleshooting must be done with the unit energized, have pre- sent another person trained in turning off the equipment and providing or calling for first aid.

c. FIRE AND EXPLOSION PREVENTION Fire and explosion are caused by electrical short circuits. Overloaded or shorted equipment can become hot enough to cause fires either by self destruction or causing nearby combustibles to ignite. Provide primary input protection to remove short circuited or heavily overloaded equipment from the line.

D. MEDICAL AND FIRST AID TREATMENT First aid facilities and a qualified first aid person should be available for each shift for immediate treatment of all injury victims. Electric shock victims should be checked by a physician and taken to a hospital immediately if any abnormal signs are observed.

I EMERGENCY FIRST AID

' Call physician immediately. Seek additional assistance and use First Aid techniques recommended by American Red Cross until medical help arrives.

IF BREATHING IS DIFFICULT, give oxygen, if available, and have victim lie down. FOR ELECTRICAL SHOCK, turn off power. Remove victim; if not breathing, begin artificial respiration, preferably mouth-to-mouth. If no detectable pulse, begin external heart massage. Call Emergency Rescue Squad immediately.

E. EQUIPMENT PRECAUTIONARY LABELS Inspect all precautionary labels on the equipment monthly. Order and replace all labels that cannot be easily read.

OM-457 CHAPTER 2. SERVICING

SECTION 1. MAINTENANCE AND INSPECTION

1. General

The power distribution box requires no scheduled maintenance and should operate for long periods of time without attention. In the event of a malfunction, maintenance is limited to the replacement of parts. A visual inspection is recommended each time the unit's panels are removed.

Periodically, the unit's air filters should be removed and cleaned. Cleaning can be done with water from a hose or faucet.

2. Parts Replacement

WARNING: HIGH VOLTAGE - ELECTRIC SHOCK CAN KILL! DISCONNECT INPUT POWER BEFORE UNIT'S PANELS ARE REMOVED AND MAKE CERTAIN THAT POWER CANNOT BE TURNED ON ACCIDENTALLY.

CAUTION: REPLACE BLOWN FUSES WITH FUSES OF PROPER TYPE AND RATING REQUIRED.

There are no high mortality parts which require periodic replacement, repair or special attention. If any parts require replacement due to damage or malfunction, refer to the Parts List for part number, etc. Occasionally it will be necessary to replace a blown fuse in the box. Below (Fig. 1) is a table of the types, ratings, functions and locations of fuses used in the box.

3. Inspection

The power distribution box requires a minimum of inspection and. checking. It is suggested that inspections and checks be coordinated with those performed on the power source (generator set). However, it is understandable that a power distribution box with a high rate of usage will require more frequent inspection than one with moderate usage. When inspecting the box, be sure to do the following:

A. Inspect ALL lead connections for security.

B. Inspect ALL connections and components for discoloration and other evidence of overheating.

c. Check transformer and subassembly hardware for security to avoid magnetic rattle.

D. Clean all dirt, dust, and debris from the interior with a vacuum cleaner or similar equipment.

1. General

A. Troubleshooting is an orderly process of checking and eliminating possible causes of trouble until the exact cause of a problem is found. As a rule, the best place to start looking for the cause of

a trouble in a circuit is at the source of power. Continue testing and checking the circuit, step-by-step, in an orderly manner, until the cause of trouble is located. See applicable connection diagrams and schematic diagrams.

B. This section provides information useful in diagnosing and correcting certain troubles which cause unsatisfactory operation or failure of the equipment.

c J. Minor troubles may be remedied by the operator; however, major repairs must be undertaken by experienced mechanics and electricians only.

2. Troubleshooting Chart

A. Description

The troubleshooting chart (Figure 1) lists information under three headings:

(1) Malfunction

(2) Test or Inspection

(3) Corrective Action

B. Use of Troubleshooting Chart

(1) The troubleshooting chart is designed to provide maintenance and repair personnel with a time-saving guide for locating the source of a trouble.

(2) A schematic diagram and connection diagrams are provided in Chapter 5.

(3) Electrical component symbols, which are used on schematic diagrams, are also used in the troubleshooting chart (in parentheses after the item name) to help maintenance personnel identify parts on the schematic diagrams.

(4) ALWAYS check circuit fuses and the position of switches first in troubleshooting. The incorrect positioning of a switch may cause a condition which could be misinterpreted as a fault.

CHAPTER 4. ILLUSTRATED PARTS LIST OM-457

SECTION 1. INTRODUCTION

1. General

The Illustrated Parts List identifies, describes, and illustrates main assemblies, subassemblies, and detail parts of a 2301400 V Power Distribution Boxes manufactured by Hobart Brothers Company, Power Systems Division, Troy, Ohio 45373.

2. Purpose

The purpose of this list is to provide parts identification and descrip- tive information to maintenance and provisioning personnel for use in provisioning, requisitioning, purchasing, storing, and issuing of spare parts.

3. Arrangement

Chapter 4 is arranged as follows:

Section 1 - Introduction Section 2 - Manufacturer's Codes Section 3 - Parts List Section 4 - Numerical Index

4. Explanation of Parts List

A. Contents

The parts list contains a breakdown of the equipment into assemblies, subassemblies, and detail parts. All parts of the equipment are listed except:

(1) Standard hardware items (attaching parts) such as nuts, screws, washers, etc., which are available commercially.

(2) Bulk items such as wire, cable, sleeving, tubing, etc., which are also commercially available.

(3) Permanently attached parts which lose their identity by being welded, soldered, riveted, etc., to other parts, weldments, or assemblies.

B. Parts List Form

This form is divided into six columns. Beginning at the left side of the form and proceeding to the right, columns are identified as follows:

July 27/84 4-l

Page 1

OM-457

(1) FIGURE-ITEM NO. Column

This column lists the figure number of the illustration applicable to a particular parts list and also identifies each part in the list by an item number. These item numbers also appear on the illustration. Each item number on an illustration is connected to the part to which is pertains by a leader line. Thus the figure and item numbering system ties the parts list to the illustrations and vice versa. The figure and index numbers are also used in the numerical index to assist the user in finding the illustration of a part when the part number is known.

(2) HOBART PART NUMBER Column

ALL part numbers appearing in this column are Hobart numbers. In all instances where the part is a purchased item, the vendor's identifying five-digit code and his part number will appear in the NOMENCLATURE column. Vendor parts which are modified by Hobart will be identified as such in the NOMENCLATURE column. In case Hobart does not have an identifying part number for a purchased part, the HOBART PART NUMBER column will reflect No Number and the vendor's number will be shown in the NOMENCLATURE column. Parts manufactured by Hobart reflect no vendor code or part number in the NOMENCLATURE column.

(3) NOMENCLATURE Column

The item identifying name appears in this column. The indenture method is used to indicate item relationship. Thus, componenents of an assembly are listed directly below the assembly and inden- ted one space. Vendor codes and part numbers for purchased parts are shown in this column.

(4) REC. SPARES Column

When there is an entry in this column, it shows the quantity of that item recommended for spares to support ONE end item.

(5) EFF (Effective) Column

This column is used to indicate the applicability of parts to different models of equipment. When more than one model of equipment is covered by a parts list, there are some parts which are used on only one model. This column is used for insertion of a code letter A, B, etc., to indicate these parts and to identify the particular model they are used on.

Parts Coded "A" are used on Model 488559 only. Parts Coded "B" are used on Model 488570 only. Parts Coded "C" are used on Model 487573-l only. Parts Coded "D" are used on Model 487573-2 only. Parts Coded "E" are used on Model 487573-3 only.

OM-457 (6) UNITS PER ASSEMBLY Column

This column indicates the quantity of parts required for an assembly or subassembly in which the part appears. This column does not necessarily reflect the total used in the complete end item.

5. Reference Designator Index

The reference designators listed in Figure 1 are the same as those used on the connection and schematic diagrams furnished in Chapter 5.

Each reference designator is cross-referenced to the Figure and Item number of that item in the Illustrated Parts List, Section 4-3.

SECTION 4. NUMERICAL INDEX

1. Explanation of Numerical Index

The purpose of this index is to assist the user in finding the illustration and description of a part when the part number is known. Part numbers are arranged in alpha-numerical sequence. Thus, any part number beginning with the letter A would be located at or near the top of the index list. Likewise a part number 9 would be listed near the end of the list and far below a part number 1000. The figure number and item number location of the part is directly opposite the part. If the part is used in more than one place, each location is listed commencing with the first location the part is listed.
