User manual
Intended use
The network switch is intended for cable-based networking of computers or other devices suit-
able for the purpose. 8 twisted-pair connections (RJ45) are available.
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.

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 consequen-
tial damage!
Nor do we 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 modifi cation of the product is not permitted for
safety and approval reasons (CE).
• The product is not a toy. Install and use the product where it is out of the reach of
children.
• The product is intended for use only in dry, closed interiors, it must not get damp
or wet.
• Two separate connections redundantly supply the product with power. It requires
two external mains adaptors (not included in the delivery), which provide a stabi-
lised direct current of 12 - 48 V/DC each.
• Do not leave packaging material carelessly lying around as it can become a dan-
gerous plaything for children.
• Handle the product with care, it can be damaged by impacts, blows, or accidental
drops, even from a low height.
Installation and Connection
Important:
If the network switch is installed in an electrical control cabinet with dangerous volt-
ages, 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 redundant. This means
that it automatically and immediately switches to the alternative voltage/power sup-
ply, if the initial voltage/power supply fails.
If you do not want to connect two separate voltage/power supplies, then one is
equally suffi cient for operating.
Terminal clamps “PW1”: Connect the fi rst 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 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 termi-
nals) is available for connection to the electrical grounding. Connect it to the electrical ground-
ing of the electrical control cabinet in which the network switch is installed.
DIP switch for alert function: If the DIP switch “power” (switch 9) 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 “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 con-
nection is disrupted (e.g. by pulling the network plug).
☞
Only move the respective switch into the “ON” position, 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
secure 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 with suitable network cables to your devices and computers.
Each of the 8 network ports supports auto uplink, which means that no expensive crosslink
cables are necessary to connect multiple network switches.
Make sure the cables are not bent or crushed.
We recommend marking the network cables with suitable adhesive labels or other devices.
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 respective DIP switch needs to be in the correct position for this, see above.
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).
Disposal
Dispose of an unserviceable product in accordance with the relevant statutory
regulations.
