appear throughout this documentation or on the device. These notes warn of
potential hazards or call attention to information that clarifies or simplifies a
procedure.
Symbol explanation
This is a general warning symbol. This symbol alerts you to
potential personal injury hazards. Observe all safety notes that
follow this symbol to avoid possible injury or death.
If this symbol is displayed in addition to a safety instruction of the
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 54.
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 these instructions can result in death, serious injury,
or equipment damage.

Installation site requirements
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.
Only for device variants featuring supply voltage with characteristic
value K9 or KK:
Install this device only in a switch cabinet or in an operating site with
restricted access, to which maintenance staff have exclusive access.
Strain relief
Note: If the strain relief is insufficient, there is a risk of torsion, contact
problems and creeping interruptions.
Relieve the connection points of cables and lines from mechanical
stress.
Design strain relieves in such a way that they prevent any mechanical
damage to cables, wires or conductors caused by external influences
or their own weight.
To 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.
Device casing
Only technicians authorized by the manufacturer are permitted to open
the casing.
Never insert pointed objects (narrow screwdrivers, wires, etc.) into the
device or into the connection terminals for electric conductors. Do not
touch the connection terminals.
Keep the ventilation slits free to ensure good air circulation.
Mount the device in the vertical position.
At ambient air temperatures > +140 °F (+60 °C):
The surfaces of the device housing may become hot. Avoid touching
the device while it is operating.
Qualification requirements for personnel
Only allow qualified personnel to work on the device.

Installation RSP20/25/30/35
Release 18 09/2021 9
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.
National and international safety regulations
Verify that the electrical installation meets local or nationally applicable
safety regulations.
Grounding the device
Grounding the device is by means of a separate ground connection on the
device.
Ground the device before connecting any other cables.
Disconnect the grounding only after disconnecting all other cables.
Ground the device via the ground screw.
Shielding ground
The overall shield of a connected shielded twisted pair cable is connected
to the grounding connector on the front panel as a conductor.
Beware of possible short circuits when connecting a cable section with
conductive shielding braiding.
Requirements for connecting electrical wires
Before connecting the electrical wires, always verify that the
requirements listed are complied with.
Requirements for connecting the signal contact
All of the following requirements are complied with:
The electrical wires are voltage-free.
The cables used are permitted for the temperature range of the application case.
Table 1: Requirements for connecting electrical wires
All of the following requirements are complied with:
The voltage connected complies with the requirements for a safety extra-low voltage
(SELV) as per IEC 60950-1 or ES1 as per IEC/EN 62368-1.
The connected voltage is limited by a current limitation device or a fuse.

The supply voltage corresponds to the voltage specified on the type
plate of the device.
The power supply conforms to overvoltage category I or II.
The power supply has an easily accessible disconnecting device (for
example a switch or a plug). This disconnecting device is clearly

the characteristic
value CC:
If you connect 2 independent power sources, verify that the minus
terminal is grounded. Failure to follow this instruction can result in
equipment damage.
