Juniper Networks J4350, J6350 manual AC Power Electrical Safety Guidelines

Chapter 14: Safety and Regulatory Compliance Information

■Install the Services 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 through Part 7.

■Evaluated to the TN power system.

■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 can be 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 Services Router within marked electrical ratings and product usage instructions.

■For the Services 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 Services Router components can be removed and replaced without powering down or disconnecting power to the Services Router, as detailed in elsewhere in this manual. Never install equipment if it appears damaged.

AC Power Electrical Safety Guidelines

CAUTION: For routers with AC power supplies, an external surge protective device (SPD) must be used at the AC power source.

The following electrical safety guidelines apply to AC-powered routers:

■AC-powered routers are shipped with a three-wire electrical cord with a grounding-type plug that fits only a grounding-type power outlet. Do not circumvent this safety feature. Equipment grounding should comply with local and national electrical codes.

■You must provide an external Listed circuit breaker rated minimum 15 A in the building installation.

■The power cord serves as the main disconnecting device. The socket outlet must be near the router and be easily accessible.
