AC Power Electrical Safety Guidelines

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 circuit breaker rated minimum 20 A, 125/250 VAC 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:
- 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.
