NOTE: In North America, AC power cords must not exceed 4.5 m
(approximately 14.75 ft) in length, to comply with National Electrical Code
(NEC) Sections 400-8 (NFPA 75, 5-2.2) and 210-52, and Canadian Electrical
Code (CEC) Section 4-010(3). The cords supplied with the router are in
compliance.
WARNING: The router is pluggable type A equipment installed in a
restricted-access location. It has a separate protective earthing terminal
(sized for UNC 1/4-20 ground lugs) provided on the chassis in addition to the
grounding pin of the power supply cord. This separate protective earthing
terminal must be permanently connected to earth.
