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.
The cores in the mains lead are colored in accordance with the following code (within the United States):
- Green and yellow—Earth
- Blue—Neutral
- Brown—Live
When a router is equipped with two AC power supplies, both power cords (one for each power supply) must be unplugged to completely disconnect power to the router.
Note the following warnings printed on the AC power supply faceplate:
- To completely de-energize the system disconnect maximum of 2 power cordsets.
- Apparaten skall anslutas till jordat uttag när den ansluts till ett nätverk. [Swedish]
