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.
Certified usage
Use the device solely for the application cases described in the
Hirschmann product information, including this manual.
Operate the device solely according to the technical specifications.
See “Technical data” on page 38.
Supply voltage
The supply voltage is electrically isolated from the housing.
The devices are designed for operation with safety extra-low voltage.
Connect only SELV circuits with voltage restrictions in line with IEC/EN
60950-1 to the supply voltage connections and signal contacts.
Connect only a supply voltage that corresponds to the type plate of
your device.
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.

6Installation RS20/RS30-...U
Release 03 08/2019
Ground the device before connecting any other cables.
Observe the maximum values for the contact load of the signal
contact.
Relevant for North America:
The device may only be connected to a Class 2 supply voltage that
fulfills the requirements of the National Electrical Code, Table 11(b). If
the voltage is being supplied redundantly (two different voltage
sources), the combined supply voltages must fulfill the requirements of
the National Electrical Code, Table 11(b).
Relevant for North America: For use in class 2 circuits.
Use 60/75 °C (140/167 °F) or 75 °C (167 °F) copper (Cu) wire only.
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.
Start connecting the electrical wires only if all the above safety
requirements are fulfilled.
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
Grounding the device
The housing is grounded via the separate ground screw on the bottom left
of the front panel.
For the ground conductor, use a wire diameter of at least 1.0 mm².
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 ground connector on the front panel as a conductor.
Beware of possible short circuits when connecting a cable section with
conductive shielding braiding.

Relevant for use in explosion hazard areas (Hazardous
Locations, Class I, Division 2):
Relevant for North America for devices certified for Hazardous Locations:
Power, input and output (I/O) wiring must be in accordance with Class I,
Division 2 wiring methods [Article 501-4(b) of the National Electrical
Code, NFPA 70] and in accordance with the authority having jurisdiction.
SUITABLE FOR USE IN CLASS I, DIVISION 2, GROUPS A, B, C AND D
HAZARDOUS LOCATIONS, OR NON-HAZARDOUS LOCATIONS
ONLY.
WARNING – EXPLOSION HAZARD – SUBSTITUTION OF ANY
COMPONENTS MAY IMPAIR SUITABLE FOR CLASS I, DIVISION 2.
WARNING – EXPLOSION HAZARD – DO NOT DISCONNECT
EQUIPMENT WHILE THE CIRCUIT IS LIVE OR UNLESS THE AREA IS
KNOWN TO BE FREE OF IGNITABLE CONCENTRATIONS.
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.
Peripheral equipment must be suitabel for the location it is used in.
Use 60/75 °C (140/167 °F) or 75 °C (167 °F) copper (Cu) wire only.
Avertissement - Risque d'explosion - Ne pas débrancher tant que le
circuit est sous tension à moins que l'emplacement soit connu pour ne
contenir aucune concentration de gaz inflammable.
Avertissement - Risque d'explosion - La substitution de tout composant
peut rendre ce matériel incompatible pour une utilisation en classe I,
division 2.
