Electrical safety, Observe the following rules when working on electrical equipment. 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, v 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, v Do not work alone under hazardous conditions or near equipment that has. hazardous voltages,v Disconnect all power before,Performing a mechanical inspection. Working near power supplies,Removing or installing main units. v 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. v 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. Attention Another person must be there to switch off the power if. Use only one hand when working with powered on electrical equipment. keep the other hand in your pocket or behind your back. Attention An electrical shock can occur only when there is a complete. circuit By observing the above rule you may prevent a current from passing. through your body, When using testers 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.

Consider these conditions and the safety hazards they present. v Electrical hazards especially primary power primary voltage on the frame can. cause serious or fatal electrical shock, v Explosive hazards such as a damaged CRT face or a bulging capacitor. v Mechanical hazards such as loose or missing hardware. To determine whether there are any potentially unsafe conditions use the. following checklist at the beginning of every service task 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 the frame ground, b The power cord should be the type specified in the parts list.
c Insulation must not be frayed or worn,4 Check for cracked or bulging batteries. 5 Remove the cover, 6 Check for any obvious non ThinkPad alterations Use good judgment as to the. safety of any non ThinkPad alterations, 7 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. 8 Check for worn frayed or pinched cables, 9 Check that the power supply cover fasteners screws or rivets have not been. removed or tampered with,Safety information 5, Handling devices that are sensitive to electrostatic discharge.
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.
