1 Introduction
These operating instructions are part of the LCOS Unmanaged Switch.
Before using the device, please read these operating instructions to avoid
possible dangers and to ensure proper use.
Short description LCOS Unmanaged (Industrial Ethernet) Switches
The LCOS unmanaged switches are highly suitable for use in industrial ethernet
networks. In addition to durability, the units also offer more performance, such as
QoS (Quality of services) or operation in Profinet and Ethernet IP. Thanks to their
modular design, the units can be supplied with power in the LCOS system either
by means of the existing connectors or via the power bus (PB). They can also be
used in building automation systems due to the fact that they can run on AC
voltage. The application temperature range is -25 °C to +70°C.
Read and understand these instructions before installing, operating, or
maintaining the equipment.
Risk of injury and damage to property due to non-observance of the
operating instructions.
Always read these operating instructions before planning the system in order
to avoid or reduce risks and damage.
These operating instructions contain important information on safety,
commissioning, operation, maintenance and disposal of the device.
Always keep the document at hand. This applies until the device is disposed of.
Pass on the operating instructions if the device is sold, distributed or loaned.
You can also find these operating instructions at www.luetze.com.

▪ generally accepted safety rules
▪ general ESD regulations.
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.

must be conform with international and national ruls and standards.
ATTENTION! The supply cable must be suitable for an operating
temperature range of -25 °C to +70 °C.
The connecting cables must be designed for the ambient temperature.
To ensure UL certification of the complete module, only use the plug-in
terminals recommended by us.
For UL applications: An UL-approved 3A fuse must be connected
upstream of the device.
For UL applications: Ambient temperature: +70 °C
The device has to be installed in a fire enclosure depending on the end

4.2 Overview of product features
4.2.1 LCOS Unmanaged Ethernet Switches
The LCOS-SW-4P or LCOS-SW-8P Unmanaged Ethernet Switch is a switch for
use in industrial environments. It supports ETHERNET 10 MBit/s and Fast
ETHERNET 100 MBit/s.
The switch modules enable the construction of switched Ethernet networks
according to the IEEE 802.3 or 802.3u standard with twisted-pair cables.
The switch modules can be mounted directly on the top-hat rail via a function
carrier and are powered either via the LCOS power bus (PB) or the 3-pole
connection terminal. With their compact design, the modules can be mounted in
a terminal box.
The LCOS-SW-4P devices have four 10/100 Mbps twisted pair ports (10/
100BASE-TX, RJ45 connectors) and the LCOS-SW-8P devices have eight 10/
100 Mbps twisted pair ports (10/100BASE-TX, RJ45 connectors).
Twisted pair devices or other TP/TX segments can be connected to the ports. The
TP ports support auto negotiation, auto polarity and auto MDI/MDI-X. In addition,
the devices evaluate the Ethernet frame-based priority data (Qos) in order to
forward time-critical signals more quickly.
The power consumption is significantly reduced by an automatic switch-off of the
unused ports, but even at full load the power consumption of the 8 port version
remains below 2W. The extended operating temperature range allows operation
from - 25 °C to + 70°C ambient temperature.
