Electrical safety
CAUTION:
Electrical current fro power, telephone, and co unication cables can be hazardous. To avoid
personal injury or equip ent da age, disconnect the attached power cords, teleco unication
syste s, networks, and ode s before you open the co puter covers, unless instructed otherwise
in the installation and configuration procedures.
Ob erve the following rule when working on electrical equipment.
I portant: U e only approved tool and te t equipment. Some hand tool have handle covered with a oft
material that doe not in ulate you when working with live electrical current . Many cu tomer have, near
their equipment, rubber floor mat that contain mall conductive fiber to decrea e electro tatic di charge .
Do not u e thi type of mat to protect your elf from electrical hock.
• Find the room emergency power-off (EPO) witch, di connecting witch, or electrical outlet. If an electrical
accident occur , you can then operate the witch or unplug the power cord quickly.
• Do not work alone under hazardou condition or near equipment that ha hazardou voltage .
• Di connect all power before:
– Performing a mechanical in pection
– Working near power upplie
– Removing or in talling Field Replaceable Unit (FRU )
• Before you tart to work on the machine, unplug the power cord. If you cannot unplug it, a k the cu tomer
to power-off the wall box that upplie power to the machine and to lock the wall box in the off po ition.
• If you need to work on a machine that ha expo ed electrical circuit , ob erve the following precaution :
– En ure that another per on, familiar with the power-off control , i near you.
Re e ber: Another per on mu t be there to witch off the power, if nece ary.
– U e only one hand when working with powered-on electrical equipment; keep the other hand in your
pocket or behind your back.
Re e ber: There mu t be a complete circuit to cau e electrical hock. By ob erving the above rule,
you may prevent a current from pa ing through your body.
– When u ing a te ter, et the control correctly and u e the approved probe lead and acce orie for
that te ter.
– Stand on uitable rubber mat (obtained locally, if nece ary) to in ulate you from ground uch a
metal floor trip and machine frame .
Ob erve the pecial afety precaution when you work with very high voltage ; the e in truction are in
the afety ection of maintenance information. U e extreme care when mea uring high voltage .
• Regularly in pect and maintain your electrical hand tool for afe operational condition.
• Do not u e worn or broken tool and te ter .
• Never assume that power ha been di connected from a circuit. Fir t, check that it ha been powered-off.
• Alway look carefully for po ible hazard in your work area. Example of the e hazard are moi t floor ,
nongrounded power exten ion cable , power urge , and mi ing afety ground .
• Do not touch live electrical circuit with the reflective urface of a pla tic dental mirror. The urface i
conductive; uch touching can cau e per onal injury and machine damage.
• Do not ervice the following part with the power on when they are removed from their normal operating
place in a machine:
2PX Hardware Maintenance Manual

– Power upply unit
– Pump
– Blower and fan
– Motor generator
and imilar unit . (Thi practice en ure correct grounding of the unit .)
• If an electrical accident occur :
– U e caution; do not become a victim your elf.

Safety inspection guide
The intent of thi in pection guide i to a i t you in identifying potentially un afe condition on the e
product . Each machine, a it wa de igned and built, had required afety item in talled to protect u er
and ervice per onnel from injury. Thi guide addre e only tho e item . However, good judgment hould
be u ed to identify potential afety hazard due to attachment of feature or option not covered by thi
in pection guide.
If any un afe condition are pre ent, you mu t determine how eriou the apparent hazard could be and
whether you can continue without fir t correcting the problem.
Con ider the e condition and the afety hazard they pre ent:
• Electrical hazard , e pecially primary power (primary voltage on the frame can cau e eriou or fatal
electrical hock).
• Explo ive hazard , uch a a damaged CRT face or bulging capacitor
• Mechanical hazard , uch a loo e or mi ing hardware
The guide con i t of a erie of tep pre ented in a checkli t. Begin the check with the power off, and the
power cord di connected.
Checkli t:
1. Check exterior cover for damage (loo e, broken, or harp edge ).
2. Power-off the computer. Di connect the power cord.
3. Check the power cord for:
a. A third-wire ground connector in good condition. U e a meter to mea ure third-wire ground
continuity for 0.1 ohm or le between the external ground pin and frame ground.
b. The power cord hould be the appropriate type a pecified in the part li ting .
c. In ulation mu t not be frayed or worn.
4. Remove the cover.
5. Check for any obviou alteration . U e good judgment a to the afety of any alteration .
6. Check in ide the unit for any obviou un afe condition , uch a metal filing , contamination, water or
other liquid , or ign of fire or moke damage.
7. Check for worn, frayed, or pinched cable .
8. Check that the power- upply cover fa tener ( crew or rivet ) have not been removed or tampered
with.

Handling electrostatic discharge-sensitive devices
Any computer part containing tran i tor or integrated circuit (IC ) hould be con idered en itive to
electro tatic di charge (ESD). ESD damage can occur when there i a difference in charge between object .
Protect again t ESD damage by equalizing the charge o that the machine, the part, the work mat, and the
per on handling the part are all at the ame charge.
Notes:
1. U e product- pecific ESD procedure when they exceed the requirement noted here.
2. Make ure that the ESD protective device you u e have been certified (ISO 9000) a fully effective.
When handling ESD- en itive part :
• Keep the part in protective package until they are in erted into the product.
• Avoid contact with other people while handling the part.
• Wear a grounded wri t trap again t your kin to eliminate tatic on your body.
• Prevent the part from touching your clothing. Mo t clothing i in ulative and retain a charge even when
you are wearing a wri t trap.
• U e the black ide of a grounded work mat to provide a tatic-free work urface. The mat i e pecially
u eful when handling ESD- en itive device .
• Select a grounding y tem, uch a tho e li ted below, to provide protection that meet the pecific
ervice requirement.
Note: The u e of a grounding y tem i de irable but not required to protect again t ESD damage.
– Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground.
– U e an ESD common ground or reference point when working on a double-in ulated or battery-
operated y tem. You can u e coax or connector-out ide hell on the e y tem .
– U e the round ground-prong of the ac plug on ac-operated computer .
Grounding require ents
Electrical grounding of the computer i required for operator afety and correct y tem function. Proper
grounding of the electrical outlet can be verified by a certified electrician.
