AC Power Electrical Safety Guidelines for the M120 Router


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.

  • Each AC power supply has two AC appliance inlets. Each requires a dedicated AC power feed. For 100-120 VAC, both inlets are used. For 200-240 VAC, only the top inlet is used. For information about site power requirements, see M120 Router Power Requirements. For information about connecting the router to power and ground, see Connecting Power to an AC-Powered M120 Router and Connecting the Grounding Cable to the M120 Router.

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

  • The cores in the mains lead are colored in accordance with the following code:

    • Green and yellow—Earth

    • Blue—Neutral

    • Brown—Live
