respective application must also be observed. This also applies analogously to the use of
accessories.
2.2 Intended Use
The ETHSW50K from Wachendorff is used to expand Ethernet networks and connect Ethernetcapable terminal devices. Any use beyond this is considered improper use.
The ETHSW50K must not be used as the sole means of averting dangerous conditions on
machines and systems. Machines and systems must be designed in such a way that faulty
states cannot lead to a situation that is dangerous for the operating personnel (e.g. by independent
limit switches, mechanical interlocks, etc.).
2.3 Qualified personnel
The ETHSW50K may only be used by qualified personnel, exclusively in accordance with the
technical data. Qualified personnel are persons who are familiar with the installation, assembly,
commissioning and operation of this device and who have a qualification corresponding to their
activity.
2.4 Residual hazards
The ETHSW50K corresponds to the state of the art and is safe to operate. The unit may present
residual hazards if used and operated improperly by untrained personnel. This manual refers to
residual hazards with the following symbol:
This symbol indicates that non-observance of the safety instructions may result
in danger to persons, serious physical injury or death and/or the possibility of
damage to property.
2.5 Liability
Liability is excluded for material and legal defects in this documentation, in particular for its
correctness, freedom from errors, freedom from third-party industrial property rights and copyrights,
completeness and/or usability - except in the case of intent or fraudulent intent.
2.5 CE conformity
The declaration of conformity is available from us. You are welcome to order them. Just call us.

5. Installation
5.1 Mechanical Installation
5.1.1 Mounting on the DIN rail
The ETHSW50K is equipped with a DIN rail holder on the rear side. Please follow the steps below
for proper mounting on the DIN rail:
1. Tilt the module backwards with the top and press it onto the DIN rail. Align the
module straight.
2. Press the module down on the DIN rail until it is properly fixed on the rail. Then close
the lock on the underside by moving it upwards. The lock is correctly performed when
you hear and perceive a click.

5.2 Electrical Installation
5.2.1 Connecting the power supply
The ETHSW50K has a redundant voltage input. This ensures trouble-free operation in the event of
a power supply failure or a voltage supply failure. Please follow the steps below for proper connection:
Provide a suitable 12 to 58 VDC power source and connect it by tightening the screws
to the 6-pole terminal plug at the terminals provided for this purpose:
o P1: Primary power supply (+ / -)
o P2: Secondary power supply (+ / -)
Check the two power LEDs P1 and P2 on the device. The LEDs light up when a
connected power supply is active. The switch is ready for operation.
Warning: Before connecting the switch to the DC voltage, make sure that it complies with
the specifications.

5.2.2 Connection of the fail safe relay
In addition to the redundant voltage input, the ETHSW50K has a fault signal relay for signalling a
fault. This ensures trouble-free operation and direct fault detection in the event of a power supply
failure or voltage supply failure. The fault signal relay is designed as a normally open contact.
For proper connection, please follow these steps:
Connect the corresponding signalling system to the connection terminals marked ALM (in the
middle of the 6-pole terminal plug, max. 1 A / 24 VDC).
Activate the fault message contact Power Alarm at PIN 1 of the DIP switch (ON).

5.2.3 Connecting the network devices
The ETHSW50K has 5 x 10/100 Mbit/s ports with RJ45 connectors. At each port there are 2 LEDs
for signalling the operating mode (see chapter "6. LED status indicators"). Proceed as follows to
ensure proper functioning:
Connect your Ethernet network devices to your Fast Ethernet Switch using a
straight-through (standard patch cable) or cross-over (UTP Unshielded Twisted pair
/STP Shielded Twisted Pair) cable with RJ-45 connectors.
An LED associated with the port lights up after a successful link up depending on the
negotiated data rate.
The LED associated with the port flashes when data transmission is in progress.

(if power alarm is activated)
not established (link down)
The ETHSW50K is an unmanaged and plug-and-play switch. The switchable Flooding Storm Control
function protects against unwanted allocation of the available transmission rate by Broad or Multicast
data frames. In addition, the ETHSW50K has a redundant voltage input and a fault relay for signalling
the fault of a power supply unit or a power supply.
