Safety Recommendations
•
Wear safety glasses if you are working under any conditions that might be hazardous to
your eyes.
•
Do not perform any action that creates a potential hazard to people or makes the
equipment unsafe.
Maintaining Safety with Electricity
Follow these guidelines when working on equipment powered by electricity.
Warning
Before working on equipment that is connected to power lines, remove jewelry
(including rings, necklaces, and watches). Metal objects will heat up when connected to
power and ground and can cause serious burns or can weld the metal object to the terminals.
(To see translated versions of this warning, refer to the appendix “Translated Safety

•
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 by turning off the power and unplugging the power cord before
doing the following:
— Installing or removing a chassis
— Working near power supplies
•
Do not work alone if potentially hazardous conditions exist.
•
Never assume that power is disconnected from a circuit. Always check.
Warning
Read the installation instructions before you connect the system to its power
source. (To see translated versions of this warning, refer to the appendix “Translated Safety
