Safety Information
When connecting the router to AC power, you must ensure that the following conditions are met:

AC power is available at the installation location.

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.
Warning: The plug-socket combination must be accessible at all times, because it serves as the main disconnecting
device. Statement 1019
Warning: Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Statement 1030
Warning: Installation of the equipment must comply with local and national electrical codes. Statement 1074
Warning: Before connecting or disconnecting the power cord, you must remove AC power from the power cord
using a suitable service disconnect.

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.

Ensure that the user-supplied AC power plug is certified for outdoor use and has a minimum rating, such as
Interpower 84131251 or Hubbell HBL316P6W (IEC/EN60309 pin-and-sleeve type connectors).

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, follow these recommendations:
— Use properly sized parts that are suitable for outdoor installation
— Use bushings that are safety certified
