Install the router in compliance with the following local, national, or international
electrical codes:
United States—National Fire Protection Association (NFPA 70), United States
National Electrical Code.
Canada—Canadian Electrical Code, Part 1, CSA C22.1.
Other countries—International Electromechanical Commission (IEC) 60364, Part 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.
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 router within marked electrical ratings and product usage instructions.
For the router and peripheral equipment to function safely and correctly, use the cables
and connectors specified for the attached peripheral equipment, and make certain
they are in good condition.
Many router components can be removed and replaced without powering off or
disconnecting power to the router. Never install equipment if it appears damaged.
