The unit is to be connected only to internal Ethernet networks without
exiting a facility and being subjected to TNVs.
To avoid electric shock, this device may only be connected to Ethernet
networks within a building that are not connected to TNV circuits. Do not use a
telephone line voltage (TNV)! (This note is particularly relevant for North
America and Canada.)
The input/output connections comply with the Safety Extra Low Voltage (SELV)
guidelines for extra-low voltage devices. With TNV circuits, higher voltages
must be expected, e.g. due to lightning strikes. Therefore, they must not be
connected to SELV circuits.
Short-circuits and electric shocks due to incorrect application of the
voltage!
Current can injure persons and destroy the device. Before commissioning,
disconnect the entire system from the power supply and check the connections
after applying power.
Accidents during installation or maintenance due to electrical voltages!
When carrying out installation or maintenance work, disconnect the modules
from the power supply (pull out the mains plug). This prevents accidents
caused by electrical voltages.
Risk of injury from electric current.
Current can injure persons and destroy the device. For this reason, disconnect
the system from the power supply before installation.
Risk of injury and material damage through non-observance of the
operating instructions.
Always read the operating instructions before planning the system in order to
avoid or reduce risks and damage. (The instruction leaflet does not replace the
operating instructions of the product.
You can also find these operating instructions at www.luetze.com.
For electrical welding work on frames, all assemblies and their
connections must be disconnected.
If electronic assemblies are mounted on the frame, then all connections to and
from these assemblies must be disconnected beforehand.
Non-observance can destroy the devices by equalising currents.
