Important information
Note: Read these instructions carefully, and familiarize yourself with the
device before trying to install, operate, or maintain it. The following notes may
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
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.
Supply voltage
The devices are designed for operation with Safety Extra-low Voltage
(SELV). Connect only SELV circuits with voltage restrictions according to
IEC 60950-1 or ES1 according to IEC/EN 62368-1 to the supply voltage
connections and to the signal contacts.
The supply voltage is electrically isolated from the housing.
Use undamaged parts.
For power supply via DC voltage: All following prerequisites are
fulfilled:
There are fuses suitable for DC voltage in the positive conductors
of the supply lines, or the voltage sources are appropriately current-
limited. Regarding the properties of this fuse: See “General
technical data” on page 67.
The negative conductors of the voltage inputs are on ground
potential.
For power supply via AC voltage: All following prerequisites are
fulfilled:
There are fuses in the supply lines, or the voltage sources are
appropriately current-limited. Regarding the properties of this fuse:
See “General technical data” on page 67.
The power sources are electrically isolated from the ground
potential.
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.

8Installation MS20/MS30
Release 14 03/2023
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.
Only use copper wire/conductors of class 1, 75 °C (167 °F).
Start connecting the electrical wires only if all the above safety
requirements are fulfilled.
Use in Hazardous Locations
Relevant for North America for modules certified for Hazardous
Locations:
This equipment is suitable for use in Class 1, Division 2, Groups A, B, C
and D or Non-Hazardous (unclassified) locations only.
Make sure that peripheral devices are suitable for the application
environment. The wiring for the voltage supply and for the inputs and
outputs (I/O) must adhere to the wiring regulations for Class 1, Division 2
[article 501(b) of the National Electrical Code (USA), NFPA 70] and to the
applicable statutory regulations.
Note: Observe the control drawing (document number 000160011DNR)
on the following pages.
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.
