type “Danger” or “Warning”, it means that there is a danger of
electric shock and failure to observe the instructions will
inevitably result in injury.
This symbol indicates the danger of hot surfaces on the device.
In connection with safety instructions, non-observance of the
instructions will inevitably result in injuries.
DANGER
DANGER draws attention to an immediately dangerous situation, which will
inevitably result in a serious or fatal accident if not observed.
WARNING
WARNING indicates a potentially hazardous situation which, if not avoided,
could result in death or serious injury.
CAUTION
CAUTION indicates a possible danger which, if not avoided, may result in
minor injuries.

Safety instructions
General safety instructions
You operate this device with electricity. Improper usage of the device
entails the risk of physical injury or significant property damage. The
proper and safe operation of this device depends on proper handling
during transportation, proper storage and installation, and careful
operation and maintenance procedures.
Before connecting any cable, read this document, and the safety
instructions and warnings.
Operate the device with undamaged components exclusively.
The device is free of any service components. In case of a damaged
or malfunctioning device, turn off the supply voltage and return the
device to Hirschmann for inspection.
Certified usage
Use the product only for the application cases described in the
Hirschmann product information, including this manual.
Operate the product only according to the technical specifications.
See “Technical data” on page 65.
Connect to the product only components suitable for the requirements
of the specific application case.
WARNING
UNCONTROLLED MACHINE ACTIONS
To avoid uncontrolled machine actions caused by data loss, configure all
the data transmission devices individually.
Before you start any machine which is controlled via data transmission, be
sure to complete the configuration of all data transmission devices.
Failure to follow this instruction can result in death, serious injury, or
equipment damage.

Release 12 01/2022 9
Installation site requirements
Install this device only in a switch cabinet or in an operating site with
restricted access, to which maintenance staff have exclusive access.
When you are selecting the installation location, make sure you
observe the climatic threshold values specified in the technical data.
Use the device in an environment with a maximum pollution degree
that complies with the specifications in the technical data.
See “Technical data” on page 65.
Strain relief
Note: If the strain relief is insufficient, there is a potential risk of torsion,
contact problems and creeping interruptions.
Relieve the connection points of cables and lines from mechanical
stress.
Design strain reliefs in such a way that they help prevent any
mechanical damage to cables, wires or conductors caused by external
influences or their own weight.
To help prevent damage to device connections, connectors and
cables, follow the instructions for proper installation in accordance with
DIN VDE 0100-520:2013-06, sections 522.6, 522.7 and 522.13.
WARNING
FIRE HAZARD
If you connect the device to a power supply that does NOT meet the
requirements for Limited Power Source, NEC Class 2 or PS2 according to
IEC/EN 62368-1 and is NOT limited to 100 W output power, the device
must be installed in either a switch cabinet or other fire enclosure.
The fire enclosure can be made of metal or plastic with fire-protection
properties of at least V-1 according to IEC 60695-11-10. Bottom openings
of the fire enclosure must NOT exceed 2 mm in diameter.
Failure to follow these instructions can result in death, serious injury,
or equipment damage.

Qualification requirements for personnel
Only allow qualified personnel to work on the device.
Qualified personnel have the following characteristics:
Qualified personnel are properly trained. Training as well as practical
knowledge and experience make up their qualifications. This is the
prerequisite for grounding and labeling circuits, devices, and systems
in accordance with current standards in safety technology.
Qualified personnel are aware of the dangers that exist in their work.
Qualified personnel are familiar with appropriate measures against
these hazards in order to reduce the risk for themselves and others.
Qualified personnel receive training on a regular basis.
Device casing
Only technicians authorized by the manufacturer are permitted to open
the casing.
Shielding ground
The shielding ground of the connectable twisted pair cables is connected
to the ground connection as a conductor.
Beware of possible short circuits when connecting a cable section with
conductive shielding braiding.
Grounding the device
The device is grounded via the separate ground screw. The grounding
screw is located on the front right side of the device for narrow casing
sizes. For the medium and wide casing sizes, the grounding screw is
located at the bottom left of the front side of the device.
See “Dimension drawings” on page 84.
Ground the device before connecting any other cables.
Disconnect the grounding only after disconnecting all other cables.
Requirements for connecting electrical wires
Before connecting the electrical wires, always verify that the
requirements listed are complied with.
The following requirements apply without restrictions:
The electrical wires are voltage-free.
The cables used are permitted for the temperature range of the application case.
Only use power supply cables that are suitable for a temperature 20 °C (36 °F)
higher than the maximum ambient air temperature at which the device is used.
Only use copper wire.
