1.3.2 Safety Precautions While Working with Electricity
Guidelines when working with electrically powered equipment:
• Locate the Power Off switch for the system being installed or serviced. In the event of an electrical acci-
dent, the user can quickly turn the power off.
• Disconnect all power by turning the circuit breakers off before:
• Installing or removing a chassis
• Working near the power supply
• Do not work alone if potential hazards exist.
• Never assume that power is disconnected from a circuit; always check the circuit.
• Inspect the work area carefully for possible hazards, such as moist floors, ungrounded power extension
cables, frayed power cords, and missing safety grounds.
• If an electrical accident occurs, proceed as follows:
• Use caution; do not become a victim yourself.
• Turn off power to the system.
• If possible, send another person to get medical aid. Otherwise, assess the condition of the victim and then
call for help.
• Determine if the person needs rescue breathing or external cardiac compressions; then, take appropriate
action.
Insure circuit breakers are OFF before starting the installation pro-
cess.
