Safety Tips

Use these tips as safety guidelines when installing or working around this equipment:

• Locate the emergency Power-off switch for the room in which you are working. Then, if an electrical

accident occurs, you can act quickly to turn off the power.

• Disconnect all power before installing or removing a chassis.
• Do not work alone if potentially hazardous conditions exist.
• Never assume that power is disconnected from a circuit. Always check.
• Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension

cables, 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.
