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.
Connect only SELV circuits with voltage restrictions in line with IEC/EN
60950-1 to the supply voltage connections and signal contacts.
The supply voltage is electrically isolated from the housing.
Use undamaged parts.
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).
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.
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.
