CAUTION: Before removing or installing components of a switch, attach an ESD

strap to an ESD point and place the other end of the strap around your bare wrist.

Failure to use an ESD strap could result in damage to the switch.

■ Install the EX Series switch 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 EX Series switch within marked electrical ratings and product usage

instructions.

■ To ensure that the EX Series switch 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 switch components without powering off or

disconnecting power to the switch, as detailed elsewhere in the hardware

documentation for this product. Never install equipment if it appears damaged.
