Before You Begin

Warning

Only trained and qualified personnel should be allowed to install, replace, or
service this equipment.

Warning

Ultimate disposal of this product should be handled according to all national
laws and regulations.

Warning

Do not work on the system or connect or disconnect cables during periods of
lightning activity.

Warning

To avoid electric shock, do not connect safety extra low voltage (SELV) circuits
to telephone network voltage (TNV) circuits. LAN ports contain SELV circuits,
and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45
connectors. Use caution when connecting cables.

The following warnings apply when you use an external power supply.

Warning

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, 15 A U.S.
(240 VAC, 10 A international) is used on the phase conductors (all
current-carrying conductors).

Warning

The device is designed to work with TN power systems.

Warning

The plug-socket combination must be accessible at all times because it serves
as the main disconnecting device.
