AC power can be readily and conveniently removed from the router. The power should not be
removed by disconnecting the AC power connector on the unit. It should be removed by disabling
AC power at the power circuit.
You must protect AC power plugs and AC receptacles from water and other outdoor elements. You
can use a UL-listed waterproofing enclosure suitable for covering the AC receptacle and AC power
plug that supplies power to the unit, as described in Article 406 of the National Electric Code (NEC).
When you install the unit outdoors, or in a wet or damp location, the AC branch circuit that powers
the unit should have ground fault protection (GFCI), as required by Article 210 of the NEC.
If the power cord goes through a metal cover, a bushing should be installed to prevent fraying of the
cord. When using a strain relief bushing, you should follow these recommendations:
Use properly sized parts
–
Use bushings that are safety certified
–
Use parts that are suitable for outdoor installation
–
Ensure that the user-supplied AC power plug is certified for outdoor use and has a minimum IP67
rating.
