CAUTION: Before removing or installing components of a device, attach an
electrostatic discharge (ESD) grounding strap to an ESD point and place the
other end of the strap around your bare wrist. Failure to use an ESD grounding
strap could result in damage to the switch.
• Install the device in compliance with the following local, national, and international
electrical codes:
•
United States—National Fire Protection Association (NFPA 70), United States
National Electrical Code.
• Other countries—International Electromechanical Commission (IEC) 60364, Part 1
through Part 7.
•
Evaluated to the TN power system.
•
Canada—Canadian Electrical Code, Part 1, CSA C22.1.
•
Locate the emergency power-off switch for the room in which you are working so that
if an electrical accident occurs, you can quickly turn off the power.
• Make sure that grounding surfaces are cleaned and brought to a bright finish before
grounding connections are made.
•
Do not work alone if potentially hazardous conditions exist anywhere in your workspace.
• Never assume that power is disconnected from a circuit. Always check the circuit before
starting to work.
•
Carefully look for possible hazards in your work area, such as moist floors, ungrounded
power extension cords, and missing safety grounds.
• Operate the device within marked electrical ratings and product usage instructions.
• To ensure that the device and peripheral equipment function safely and correctly, use
the cables and connectors specified for the attached peripheral equipment, and make
certain they are in good condition.
You can remove and replace many device components without powering off or
disconnecting power to the device, as detailed elsewhere in the hardware documentation
for this device. Never install an equipment that it appears to be damaged.
