Terminal clamps “PW1”:
Connect the first 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 “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 network connections).
The relay switch contact may only be exposed to a direct current of 24 V/DC and an electric cur-
rent of 1 A maximum.
Earth connection:
The screw contact marked with an earth symbol (next to the 6 screw terminals)
is available 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 6) has been placed in the “ON”
position, the relay is activated for the alarm connector if one of the two voltage/power supplies
fails. To allow this function to operate properly, two voltage/power supplies need to be connected
to the network switch.
DIP switches “1” to “5” belong to the 5 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).
Move the respective switch into the “ON” position only if the corresponding network
port is really in use; otherwise the relay may be permanently activated for the alarm
connector.
• After all connections and settings are complete, place the network switch on the DIN rail and fix
it in place.
The DIN rail has to comply with EN55022 (overall width 3.5 cm, overall height 0.75 cm). The
network switch cannot be installed on any other mounting rails!
• Connect the RJ45 sockets to your devices and computers using suitable network cables.
Each of the four RJ45 network ports supports auto uplink, which means that no crosslink cables
are necessary to connect multiple network switches.
A suitable SFP module is required for the SFP slot (not included, available separately).
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.
Naturally, the respective DIP switch needs to be in the correct position for this; see
above.
The two LEDs in the RJ45 sockets indicate the LINK status. For this purpose, the green LED is
used for normal network devices, the yellow LED for so-called PD (“Powered Device”) network
devices.
The green “SFP” LED lights up when a data connection is present through the SFP module (LINK
status indicator).
Disposal
The product must not be disposed of in the household waste.

Operating instructions
5-Port gigabit switch for DIN rail
Item no. 1274942
Intended use
The network switch is intended for cable-based networking of computers or other devices suit-
able for the purpose. It provides 5 network connections (four twisted-pair/RJ45 sockets and one
SFP port).
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 in-
structions.
This product complies with the applicable national and European requirements. All names of com-
panies and products are the trademarks of the respective owners. All rights reserved.
Package contents
• Network switch
• Connection plug (may already be plugged into the back of the network switch on delivery)
• CD with manufacturer’s operating instructions (in English)
• Quick guide
Explanation of symbols
The lightning symbol inside a triangle is a warning to inform you of potential risks of
your health and life, such as electrical shock.
This symbol indicates specific risks associated with handling, function and use.
The “arrow” symbol indicates special tips and operating information.
Safety instructions
Damage due to failure to follow these operating instructions will void the warranty!
We do not assume any liability for any resulting damage!
We do not assume any liability for material and personal damage caused by improper
use or non-compliance with the safety instructions! In such cases, the warranty will
be null and void.
• The unauthorised conversion and/or modification of the product is not permitted for
safety and approval reasons (CE).
• The product is not a toy and does not belong in the hands 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 to be installed in an electrical control cabinet where dangerous
voltages are present, do not carry out the connection and installation yourself; rather,
have it done by a qualified specialist (e.g. electrician) who is familiar with the regula-
tions and safety precautions.
Otherwise, there is a risk of a life-threatening electric shock!
Connect and install the network switch only when it is disconnected from the mains
voltage.
• On the back of the network switch, you will find a 6-pin screw terminal to which the voltage/
power supply is to be connected; the alarm output 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 voltage/power supply fails.
If you cannot or do not want to connect two separate voltage/power supplies, a single
one is of course sufficient for operating the device.
