This product relies on the building’s installation for short-circuit (overcurrent)
protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S.
(240 VAC, 10A international) is used on the phase conductors (all
current-carrying conductors).
Warning
Before working on equipment that is connected to power lines, remove jewelry
(including rings, necklaces, and watches). Metal objects will heat up when
connected to power and ground and can cause serious burns or weld the metal
object to the terminals.
Warning
The ports labeled "10BaseT", 100BaseTX", and "10/100" are safety extra-low
voltage (SELV) circuits. SELV circuits should only be connected to other SELV
circuits. Avoid connecting these circuits to telephone network voltage (TNV)
circuits.
