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.

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
