This product relies on the building’s installation for short-circuit (overcurrent) protection. For an AC installation,
ensure that the branch circuit breaker is rated a maximum 20A.
Warning
When you connect or disconnect the power and relay connector with power applied, an electrical arc can
occur. This could cause an explosion in hazardous area installations. Be sure that power is removed from the
switch and alarm circuit. Be sure that power cannot be accidentally turned on or verify that the area is
nonhazardous before proceeding. Failure to securely tighten the power and relay connector captive screws
can result in an electrical arc if the connector is accidentally removed. Statement 1058
Warning
Take care when connecting units to the supply circuit so that wiring is not overloaded. Statement 1018
Warning
The plug-socket combination must be accessible at all times, because it serves as the main disconnecting
device. Statement 1019
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 RJ45 connectors. Use caution when connecting cables. Statement 1021
Warning
A readily accessible two-poled disconnect device must be incorporated in the fixed wiring. Statement 1022
Warning
To reduce the risk of fire, use only 26 AWG or larger telecommunication line cord. Statement 1023
Warning
This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence
of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician
if you are uncertain that suitable grounding is available. Statement 1024
Warning
Use copper conductors only. Statement 1025
Warning
This unit might have more than one power supply connection. All connections must be removed to de-energize
