Before you start the machine ensure that other service representatives and the customer s personnel are. not in a hazardous position, Place removed covers and other parts in a safe place away from all personnel while you are servicing. the machine, Keep your tool case away from walk areas so that other people will not trip over it. Do not wear loose clothing that can be trapped in the moving parts of a machine Ensure that your sleeves. are fastened or rolled up above your elbows If your hair is long fasten it. Insert the ends of your necktie or scarf inside clothing or fasten it with a nonconductive clip approximately. 8 centimeters 3 inches from the end, Do not wear jewelry chains metal frame eyeglasses or metal fasteners for your clothing.
Remember Metal objects are good electrical conductors. Wear safety glasses when you are hammering drilling soldering cutting wire attaching springs using. solvents or working in any other conditions that might be hazardous to your eyes. After service reinstall all safety shields guards labels and ground wires Replace any safety device. that is worn or defective, Reinstall all covers correctly before returning the machine to the customer. Electrical safety, Electrical current from power telephone and communication cables can be hazardous To avoid. personal injury or equipment damage disconnect the attached power cords telecommunication. systems networks and modems before you open the computer covers unless instructed otherwise. in the installation and configuration procedures,Copyright Lenovo 2015 3. Observe the following rules when working on electrical equipment. Important Use only approved tools and test equipment Some hand tools have handles covered with a soft. material that does not insulate you when working with live electrical currents Many customers have near. their equipment rubber floor mats that contain small conductive fibers to decrease electrostatic discharges. Do not use this type of mat to protect yourself from electrical shock. Find the room emergency power off EPO switch disconnecting switch or electrical outlet If an electrical. accident occurs you can then operate the switch or unplug the power cord quickly. Do not work alone under hazardous conditions or near equipment that has hazardous voltages. Disconnect all power before,Performing a mechanical inspection. Working near power supplies, Removing or installing Field Replaceable Units FRUs.
Before you start to work on the machine unplug the power cord If you cannot unplug it ask the customer. to power off the wall box that supplies power to the machine and to lock the wall box in the off position. If you need to work on a machine that has exposed electrical circuits observe the following precautions. Ensure that another person familiar with the power off controls is near you. Remember Another person must be there to switch off the power if necessary. Use only one hand when working with powered on electrical equipment keep the other hand in your. pocket or behind your back, Remember There must be a complete circuit to cause electrical shock By observing the above rule. you may prevent a current from passing through your body. When using a tester set the controls correctly and use the approved probe leads and accessories for. that tester, Stand on suitable rubber mats obtained locally if necessary to insulate you from grounds such as. metal floor strips and machine frames, Observe the special safety precautions when you work with very high voltages these instructions are in. the safety sections of maintenance information Use extreme care when measuring high voltages. Regularly inspect and maintain your electrical hand tools for safe operational condition. Do not use worn or broken tools and testers, Never assume that power has been disconnected from a circuit First check that it has been powered off. Always look carefully for possible hazards in your work area Examples of these hazards are moist floors. nongrounded power extension cables power surges and missing safety grounds. Do not touch live electrical circuits with the reflective surface of a plastic dental mirror The surface is. conductive such touching can cause personal injury and machine damage. Do not service the following parts with the power on when they are removed from their normal operating. places in a machine,Power supply units,Blowers and fans.
Motor generators, and similar units This practice ensures correct grounding of the units. If an electrical accident occurs,Use caution do not become a victim yourself. Switch off power, 4 ideacentre 300S Series Hardware Maintenance Manual. Send another person to get medical aid,Safety inspection guide. The intent of this inspection guide is to assist you in identifying potentially unsafe conditions on these. products Each machine as it was designed and built had required safety items installed to protect users. and service personnel from injury This guide addresses only those items However good judgment should. be used to identify potential safety hazards due to attachment of features or options not covered by this. inspection guide, If any unsafe conditions are present you must determine how serious the apparent hazard could be and.
whether you can continue without first correcting the problem. Consider these conditions and the safety hazards they present. Electrical hazards especially primary power primary voltage on the frame can cause serious or fatal. electrical shock, Explosive hazards such as a damaged CRT face or bulging capacitor. Mechanical hazards such as loose or missing hardware. The guide consists of a series of steps presented in a checklist Begin the checks with the power off and. the power cord disconnected, 1 Check exterior covers for damage loose broken or sharp edges. 2 Power off the computer Disconnect the power cord. 3 Check the power cord for, a A third wire ground connector in good condition Use a meter to measure third wire ground. continuity for 0 1 ohm or less between the external ground pin and frame ground. b The power cord should be the appropriate type as specified in the parts listings. c Insulation must not be frayed or worn,4 Remove the cover. 5 Check for any obvious alterations Use good judgment as to the safety of any alterations. 6 Check inside the unit for any obvious unsafe conditions such as metal filings contamination water or. other liquids or signs of fire or smoke damage,7 Check for worn frayed or pinched cables.
8 Check that the power supply cover fasteners screws or rivets have not been removed or tampered with. Handling electrostatic discharge sensitive devices. Any computer part containing transistors or integrated circuits ICs should be considered sensitive to. electrostatic discharge ESD ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the machine the part the work mat and the. person handling the part are all at the same charge. 1 Use product specific ESD procedures when they exceed the requirements noted here. 2 Make sure that the ESD protective devices you use have been certified ISO 9000 as fully effective. When handling ESD sensitive parts, Keep the parts in protective packages until they are inserted into the product. Chapter 2 Safety information 5, Avoid contact with other people while handling the part. Wear a grounded wrist strap against your skin to eliminate static on your body. Prevent the part from touching your clothing Most clothing is insulative and retains a charge even. when you are wearing a wrist strap, Use the black side of a grounded work mat to provide a static free work surface The mat is especially. useful when handling ESD sensitive devices, Select a grounding system such as those listed below to provide protection that meets the specific. service requirement, Note The use of a grounding system is desirable but not required to protect against ESD damage.
Attach the ESD ground clip to any frame ground ground braid or green wire ground. Use an ESD common ground or reference point when working on a double insulated or. battery operated system You can use coax or connector outside shells on these systems. Use the round ground prong of the ac plug on ac operated computers. Grounding requirements, Electrical grounding of the computer is required for operator safety and correct system function Proper. grounding of the electrical outlet can be verified by a certified electrician. Safety notices, The caution and danger safety notices in this section are provided in the language of English. Electrical current from power telephone and communication cables is hazardous.
