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 the device, turn off the supply voltage and return the
device to Hirschmann for inspection.
Intended 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 “General technical data” on page 53.
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.

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.
Installation site requirements
Install the device in a fire enclosure according to EN 60950-1.
Install this device only in a switch cabinet or in an operating site with
restricted access, to which maintenance staff have exclusive access.
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.
See “General technical data” on page 53.
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.
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
The device is grounded by the separate ground screw on the front panel.
Use a wire diameter for the ground conductor that is no smaller than
the diameter of the supply voltage connection, however of at least
0.75 mm² (AWG18).
Ground the device before connecting any other cables.
Disconnect the grounding only after disconnecting all other cables.
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.
Supply voltage
The supply voltage is electrically isolated from the housing.
The devices are designed for operation with safety extra-low voltage.
Connect only safety extra-low voltage circuits with voltage restrictions
in line with IEC/EN 60950-1 to the supply voltage connections and
signal contacts.
Exclusively connect a supply voltage that corresponds to the type
plate of your device.
Ground the device before connecting any other cables.
Exclusively for device variants featuring supply voltage with
characteristic value C:
The power supply is Class 2 compliant.
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 identified. So in the case of an emergency, it is clear which
disconnecting device belongs to which power supply cable.
The electrical wires are voltage-free.
A fuse suitable for DC voltage is located in the plus conductor of the
power supply.
The minus conductor is on ground potential. Otherwise, a fuse is
also located in the minus conductor.
Regarding the properties of this fuse:
See “General technical data” on page 53.
The wire diameter of the power supply cable is at least 0.75 mm²
(North America: AWG18) on the supply voltage input.

10 Installation RSR20/RSR30
Release 06 07/2021
The cables used are permitted for the temperature range of the
application case.
Relevant for North America:
The power supply cables are suitable for ambient air temperatures
of at least 167 °F (75 °C). The power supply cable wires are made
of copper.
Note: If you connect 2 independent power sources, verify that the minus
terminal is grounded. Failure to follow this instruction can result in
equipment damage.
Start connecting the electrical wires only if all the above safety
requirements are fulfilled.
Internal fuses are triggered only in the case of a detected error in the
device. In case of damage or malfunction of the device, turn off the
supply voltage and return the device to the plant for inspection.
For supply voltage connections with protective conductor connection:
First connect the protective conductor before connecting the wires for
the supply voltage.
If your device comprises a 2nd supply voltage connection of this type:
First connect the protective conductor before connecting the wires for
the supply voltages.
Enable the supply voltage for the device only when the following
requirements are fulfilled:
the housing is closed
the terminal blocks are wired correctly
the terminal blocks for the power supply are connected
Relevant for use in explosion hazard areas (Hazardous
Locations, Class I, Division 2):
SUITABLE FOR USE IN CLASS I, DIVISION 2, GROUPS A, B, C AND D
HAZARDOUS LOCATIONS, OR NONHAZARDOUS LOCATIONS
ONLY.
Replacing components of any kind can affect the suitability for Class I,
Division 2.
The USB connector is for temporary connection only. Do not use,
connect, or disconnect unless area is known to be non-
hazardous. Connection or disconnection in an explosive
atmosphere could result in an explosion.
Do not disconnect equipment unless power has been switched off or the
area is known to be non-hazardous.
