Certified usage
Please observe the following: The device may only be employed for the
purposes described in the catalog and technical description, and only in
conjunction with external devices and components recommended or
approved by the manufacturer. The product can only be operated
correctly and safely if it is transported, stored, installed and assembled
properly and correctly. Furthermore, it must be operated and serviced
carefully.
Supply voltage
For safety reasons the devices have been designed to operate at low
voltages. Thus, they may only be connected to the supply voltage
connections and to the signal contact with SELV circuits with the voltage
restrictions in accordance with IEC/EN 60950-1.
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.
Use 60/75 °C (140/167 °F) or 75 °C (167 °F) copper (Cu) wire only.
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.
The device does not contain any service components. Internal fuses
are only triggered if there is a fault in the device. If the device is not
functioning correctly, or if it is damaged, switch off the voltage supply
and return the device to the plant for inspection.
Only switch on the supply voltage for the device when the following
prerequisites are fulfilled:
The housing is closed
The terminal blocks are wired correctly
The terminal blocks for the voltage supply are connected
