3.1 Content of the Manual
Read and follow the manual before using the product the first time.
This applies to every person which is getting in touch with the product. Trained
employees and experts especially qualified persons which had worked with
similar products before have to read and understand the manual.
3.2 Intended Use
Appropriate use includes compliance with the operating instructions.
The DIOSWITCH must only be used for the intended cases provided in the
technical documents and only in combination with the third party equipment and
components recommended or approved by us.
The fault-free and reliable operation of the product requires proper transport,

A 24 V DC power supply is used for the power supply of the DIOSWITCH.
The operating voltage of 24 V DC is in the category SELV (Safety Extra Low
Voltage) or PELV (Protective Extra Low Voltage) and is thus not subject to the EC
Low Voltage Directive. The use of other power supplies is not permitted.
3.3 Recepients
The operating manual addresses planers, project manager and programmers. It
also addresses the operating employees which are responsible for the initial
operation, the operation and for the maintenance of the products and systems.
Regarding the employees three qualification levels are differentiated.
3.4 Operating Employees
Trained Employees
The employee was trained by the employer on the task and possible hazardous
situations. The employee does not have any technical knowledge.
Experts
The employee has a technical education, knowledge and/or experience in the
required field. The employee is capable to do specific operations on and with the
product.
Electrically qualified persons
The employee has a technical education in the required field. The employee is
capable to do special operations on and with the product.
The different sections of the manual refering to the qualification level of the
operating employees.
Risk of injury by deploying insufficient qualified operating employees.
Inappropriate appoint of not qualified or insufficient personnel can cause
property damages and personal injuries. Tasks which apply special procedures
should be done by trained and qualified employees or experts, especially
electricians.

3.5 Responsibility of the Operator
The operator is obligate by the law of occupational safety, if the product is used
in a commercial field.
▪ The operator is responsible to train the employees and to inform himself about
the industrial safety regulation.
▪ The operator is responsible that safety, environment protection regulations
and rules for accident prevention are observed.
▪ The operator has to run a risk assessment at the working environment/place
of installation to expose hazards and to alert those.
▪ The manual has to be stored near the product.
▪ The manual has to be obeyed.
▪ The product can just be run in a faultless technical condition.
3.6 Protective Clothing and Equipment
3.7 Other Safety Instructions
The DIOSWITCH corresponds to the state of the art and satisfies the applicable
safety conditions and the corresponding, harmonised European standards (EN).
The following are applicable for the user:
▪ relevant accident prevention regulations
▪ EC Directives or other country-specific regulations
▪ generally recognised technical safety rules
▪ general ESD regulations.
▪Destroyed parts and malfunction of the product. Inappropriate clothes
can cause electrification and can damage the product. If working with or on
the I/O Modules wear special ESD clothing.
▪ Also follow the instructions and regulations of the employer.
▪The modules must be disconnected from the mains power supply
(unplug mains plug) when installation or maintenance work is
performed. Accidents due to electrical voltages can be avoided in this way.
▪Personal injuries and property damages caused by reconstructions
and modifications of the product. Do not reconstruct or modify the product
if the manufacturer does not allow it explicit in writing.
▪This is a Class A device. This device can cause radio interference in
residential areas. In this case, the operator can be requested to perform
appropriate actions.

▪If electrical welding work is performed on the frame where electronic
components are installed, all connections to and from these
components must be disconnected in advance. It is only in this way that
the modules can be protected from destruction due to compensating
currents.
▪ Any kind of faults or other damage must be reported to a responsible person.
▪ Protection and safety devices must not be bypassed or rendered ineffective.
Dismantled safety devices must be reinstalled before starting up again and
must be subjected to a functional test.
▪ The modules must be secured against misuse or inadvertent use.
▪ Originally applied warning and information signs, lettering, stickers or similar
must always be observed and maintained in a legible condition.

7.2 Power Supply of the IP67 DIOSWITCH
The power supply connection of the IP67 DIOSWITCH is designed as a 5-pin M12
plug connector with A-coding. The connections are protected against reverse
polarity.
The shielding of the IP67 DIOSWITCH can be made either using Pin 5 of the
power supply connector or via the earth screw on the left side of the case.
The IP67 DIOSWITCH has a protective earth connection. This protective earth
connection is led out via the earth screw (X10) on the left side of the case.
Fig. 5: IP67 DIOSWITCH power supply connector
Fig. 6: IP67 DIOSWITCH power supply connector pin assignment
The DIOSWITCH is designed for operation with Safety Extra Low Voltage
(SELV). Accordingly only safety extra low voltages (SELV) according to IEC950/
EN60950/VDE0805 or protective extra low voltages (PELV) according to EN
50178 are permitted to be connected to the power supply connections.
The shielding does not provide contact protection for persons.
It is used for improving the interference resistance. The DIOSWITCH must be
earthed so that possible interference is kept away from data transmission
sections and can be routed to the earth.

8 Functional Description
8.1 General Functions
8.1.1 Behaviour when applying the voltage
All LEDs light briefly after applying the voltage.
Afterwards, the connected devices with the corresponding characteristics are
connected to the DIOSWITCH.
8.1.2 Link Detection
If a participant is connected to a port, the "Link" LED of the respective port lights.
8.1.3 Auto Negotiation
This method makes it possible for the DIOSWITCH to automatically detect the
connected network port and the correct transmission speed and to configure itself
accordingly.
FDX Detection
The DIOSWITCH automatically detects whether the connection between the
DIOSWITCH and the participant should be made in Half Duplex or Full Duplex
mode.
Speed Detection
The DIOSWITCH automatically detects whether a port is connected to a 10 MBit
segment or a 100 MBit segment and displays this using the "Speed" LED.
8.1.4 Signal Generation
The DIOSWITCH conditions signal form and amplitude of the received signals.
