Electrical sa ety
CAUTION:
Electrical current rom 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 be ore you open the computer covers, unless instructed otherwise
in the installation and con iguration procedures.
Observe the ollowing rules when working on electrical equipment.
Important: Use only approved tools and test equipment. Some hand tools have handles covered with a so t
material that does not insulate you when working with live electrical currents. Many customers have, near
their equipment, rubber loor mats that contain small conductive ibers to decrease electrostatic discharges.
Do not use this type o mat to protect yoursel rom electrical shock.
• Find the room emergency power-o (EPO) switch, disconnecting switch, or electrical outlet. I 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 be ore:
– Per orming a mechanical inspection
– Working near power supplies
– Removing or installing Field Replaceable Units (FRUs)
• Be ore you start to work on the machine, unplug the power cord. I you cannot unplug it, ask the customer
to power-o the wall box that supplies power to the machine and to lock the wall box in the o position.
• I you need to work on a machine that has exposed electrical circuits, observe the ollowing precautions:
– Ensure that another person, amiliar with the power-o controls, is near you.
Remember: Another person must be there to switch o the power, i 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 rom passing through your body.
– When using a tester, set the controls correctly and use the approved probe leads and accessories or
that tester.
– Stand on suitable rubber mats (obtained locally, i necessary) to insulate you rom grounds such as
metal loor strips and machine rames.
Observe the special sa ety precautions when you work with very high voltages; these instructions are in
the sa ety sections o maintenance in ormation. Use extreme care when measuring high voltages.
• Regularly inspect and maintain your electrical hand tools or sa e operational condition.
• Do not use worn or broken tools and testers.
• Never assume that power has been disconnected rom a circuit. First, check that it has been powered-o .
• Always look care ully or possible hazards in your work area. Examples o these hazards are moist loors,
nongrounded power extension cables, power surges, and missing sa ety grounds.
• Do not touch live electrical circuits with the re lective sur ace o a plastic dental mirror. The sur ace is
conductive; such touching can cause personal injury and machine damage.
2P340 Hardware Maintenance Manual

• Do not service the ollowing parts with the power on when they are removed rom their normal operating
places in a machine:
– Power supply units
– Pumps
– Blowers and ans
– Motor generators
and similar units. (This practice ensures correct grounding o the units.)
• I an electrical accident occurs:
– Use caution; do not become a victim yoursel .
– Switch o power.
– Send another person to get medical aid.
Sa ety inspection guide
The intent o this inspection guide is to assist you in identi ying potentially unsa e conditions on these
products. Each machine, as it was designed and built, had required sa ety items installed to protect users
and service personnel rom injury. This guide addresses only those items. However, good judgment should
be used to identi y potential sa ety hazards due to attachment o eatures or options not covered by this
inspection guide.
I any unsa e conditions are present, you must determine how serious the apparent hazard could be and
whether you can continue without irst correcting the problem.
Consider these conditions and the sa ety hazards they present:
• Electrical hazards, especially primary power (primary voltage on the rame can cause serious or atal
electrical shock).
• Explosive hazards, such as a damaged CRT ace or bulging capacitor
• Mechanical hazards, such as loose or missing hardware
The guide consists o a series o steps presented in a checklist. Begin the checks with the power o , and the
power cord disconnected.
Checklist:
1. Check exterior covers or damage (loose, broken, or sharp edges).
2. Power-o the computer. Disconnect the power cord.
3. Check the power cord or:
a. A third-wire ground connector in good condition. Use a meter to measure third-wire ground
continuity or 0.1 ohm or less between the external ground pin and rame ground.
b. The power cord should be the appropriate type as speci ied in the parts listings.
c. Insulation must not be rayed or worn.
4. Remove the cover.
5. Check or any obvious alterations. Use good judgment as to the sa ety o any alterations.
6. Check inside the unit or any obvious unsa e conditions, such as metal ilings, contamination, water or
other liquids, or signs o ire or smoke damage.
7. Check or worn, rayed, or pinched cables.
Chapter 1.Important sa ety in ormation 3

8. Check that the power-supply cover asteners (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 di erence 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.
Notes:
1. Use product-speci ic ESD procedures when they exceed the requirements noted here.
2. Make sure that the ESD protective devices you use have been certi ied (ISO 9000) as ully e ective.
When handling ESD-sensitive parts:
• Keep the parts in protective packages until they are inserted into the product.
• 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 rom touching your clothing. Most clothing is insulative and retains a charge even when
you are wearing a wrist strap.
• Use the black side o a grounded work mat to provide a static- ree work sur ace. The mat is especially
use ul when handling ESD-sensitive devices.
• Select a grounding system, such as those listed below, to provide protection that meets the speci ic
service requirement.
Note: The use o a grounding system is desirable but not required to protect against ESD damage.
– Attach the ESD ground clip to any rame ground, ground braid, or green-wire ground.
– Use an ESD common ground or re erence 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 o the ac plug on ac-operated computers.
Grounding requirements
Electrical grounding o the computer is required or operator sa ety and correct system unction. Proper
grounding o the electrical outlet can be veri ied by a certi ied electrician.
