8-Port Network Switch
for DIN rail
Item no. 41 99 65
Intended use
The network switch is intended for cable-based networking of computers or other devices suitable for the
purpose. It provides 8 network connections (6x twisted-pair/RJ45 sockets and 2 optical ports).
It is installed on a commercially available DIN rail according to EN 55022.
Always observe the safety instructions and all other information included in these operating instructions.
This product complies with the applicable national and European requirements. All names of companies and

Safety Instructions
The warranty will be void in the event of damage caused by failure to observe these safety
instructions! We do not assume any liability for any resulting damage!
We shall not accept liability for damage to property or personal injury caused by incorrect
handling or non-compliance with the safety instructions! In such cases, the warranty will
be null and void.
• The unauthorised conversion and/or modifi cation of the product is not permitted for safety and
approval reasons (CE).
• The product is not a toy and should be kept out of the reach of children. Install and use the
product where it is out of the reach of children.
• The product is only intended for use in dry, enclosed spaces, it must not get damp or wet.
• Two separate connections redundantly supply the product with power. It requires two external
mains adapters (not included in the delivery), which provide a stabilised direct current of 12 -
48 V/DC each.
• Do not leave packaging material carelessly lying around, since it could become a dangerous
plaything for children.
• Handle the product with care; it can be damaged by impacts, blows, or accidental falls, even
from a low height.
Installation and Connection
Attention, important:
If the network switch is installed in an electrical control cabinet with dangerous voltages, do not
carry out the connection and installation by yourself, but leave it to a qualifi ed specialist (e.g.
electrician), who is familiar with the regulations and safety precautions.
Otherwise, there is a risk of a life-threatening electric shock!
Only connect and install the network switch, when it is disconnected from the mains voltage.
• The voltage/power supply shall be connected to a 6-pole screw terminal at the back of the network switch;
the alarm connector is also located there.
The voltage/power supply to the network switch is designed redundantly. This means that it
automatically and immediately switches to the alternative voltage/power supply, if the initial volt-
age/power supply fails.
If you do not want to connect two separate voltage/power supplies, then one is equally suffi cient
for operating the device.
Terminal clamps "PW1": Connect the fi rst external voltage/power supply here. It needs to provide a sta-
bilised direct current of 12 - 48 V/DC and an electric current of 1 A. Always be aware of the correct polarity
(plus/+ and minus/ -).
Terminal clamps "PW2": If available, connect the second external voltage/power supply here. It needs to
provide a stabilised direct current of 12 - 48 V/DC and an electric current of 1 A. Always be aware of the
correct polarity (plus/+ and minus/ -).
:
Terminal clamps "Alm" Both terminal clamps are connected free of potential with an internal relay. The
connection is made if an alert is triggered by the network switch (e.g. during failure of one of the two voltage/
power supplies or during disruption of one of the 8 network connections).
The relay switch contact may only be exposed to a direct current of 24 V/DC and an electric current of 1 A
maximum.
Earth connection: The screw contact marked with an earth symbol (next to the 6 screw terminals) is avail-

able for connection to the electrical grounding. Connect it to the electrical grounding of the electrical control
cabinet in which the network switch is installed.
DIP switch for alert function: If the DIP switch "power" (DIP switch 9) has been placed in the "ON" position,
Version 04/13
the relay is activated for the alarm connector if one of the two voltage/power supplies fails. To allow this func-
tion to operate properly, two voltage/power supplies need to be connected to the network switch.
DIP switches "1" to "8" belong to the 8 network ports on the front. If the respective DIP switch is in the "ON"
position, the alarm connector relay is activated when the respective network connection is disrupted (e.g.
by pulling the network plug).
• After all connections and settings are complete, place the network switch on the DIN rail and fi x it in place.
The DIN rail has to comply with EN55022 (overall width 3.5 cm, overall height 0.75 cm). The network
switch may not be installed on any other mounting rails!
• Connect the RJ45 sockets to your devices and computers using suitable network cables.
Each of the 6 RJ45 network ports supports auto uplink, which means that no expensive crosslink cables
are necessary to connect multiple network switches.
Connect the 2 optical network ports to other optical network devices using suitable cables. While doing
this, pay attention to the correct connection (RX->TX, TX-RX). Only remove the respective rubber plug of
the optical network ports if the network port is really in use because the rubber plugs are meant to protect
the ports from dust.
Make sure the cables are not bent or crushed.
We recommend marking the network cables with suitable adhesive labels or other means. This will allow
you in case of a fault to know perfectly which connections need to be checked.
• Switch on the voltage/power supply.
• The green LEDs "PWR1" and "2" light up, if the respective voltage/power supply is working properly.
The red LED "Alm" lights up, if one of the two voltage/power supplies has failed or disruption has been
detected at one of the network ports.
The LEDs in the RJ45 sockets show the LINK status (network connection working properly, LED lights up
green permanently) or a data transfer in progress (LED fl ashes green); a yellow fl ashing LED shows a 100
Mbit connection (yellow LED disappears at 10 Mbit).
Two LEDs above the optical network ports show the LINK status (network connection working properly,
LED lights permanently) or a data transfer in progress (LED fl ashes) for the corresponding optical network
port.
