v
Make sure that the insulation is not frayed or worn.
4.
Remove the cover.
5.
Check for any obvious non-IBM alterations. Use good judgment as to the safety
of any non-IBM alterations.
6.
Check inside the system for any obvious unsafe conditions, such as metal
filings, contamination, water or other liquid, or signs of fire or smoke damage.
7.
Check for worn, frayed, or pinched cables.
8.
Make sure that the power-supply cover fasteners (screws or rivets) have not
been removed or tampered with.
Guidelines for servicing electrical equipment
Observe these guidelines when you service electrical equipment.
v
Check the area for electrical hazards such as moist floors, nongrounded power
extension cords, and missing safety grounds.
v
Use only approved tools and test equipment. Some hand tools have handles that
are covered with a soft material that does not provide insulation from live
electrical current.
v
Regularly inspect and maintain your electrical hand tools for safe operational
condition. Do not use worn or broken tools or testers.
v
Do not touch the reflective surface of a dental mirror to a live electrical circuit.
The surface is conductive and can cause personal injury or equipment damage if
it touches a live electrical circuit.
v
Some rubber floor mats contain small conductive fibers to decrease electrostatic
discharge. Do not use this type of mat to protect yourself from electrical shock.
v
Do not work alone under hazardous conditions or near equipment that has
hazardous voltages.
v
Locate the emergency power-off (EPO) switch, disconnecting switch, or electrical
outlet so that you can turn off the power quickly in the event of an electrical
accident.
v
Disconnect all power before you perform a mechanical inspection, work near
power supplies, or remove or install main units.
v
Before you work on the equipment, disconnect the power cord. If you cannot
disconnect the power cord, have the customer power-off the wall box that
supplies power to the equipment and lock the wall box in the off position.
v
Never assume that power has been disconnected from a circuit. Check it to
make sure that it has been disconnected.
v
If you have to work on equipment that has exposed electrical circuits, observe
the following precautions:
– Make sure that another person who is familiar with the power-off controls is
near you and is available to turn off the power if necessary.
– When you work with powered-on electrical equipment, use only one hand.
Keep the other hand in your pocket or behind your back to avoid creating a
complete circuit that could cause an electrical shock.
– When you use a tester, set the controls correctly and use the approved probe
leads and accessories for that tester.
– Stand on a suitable rubber mat to insulate you from grounds such as metal
floor strips and equipment frames.
v
Use extreme care when you measure high voltages.
