Certified usage
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 cor-
rectly and safely if it is transported, stored, installed and assembled pro-
perly 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.
Note: Only the PoE media module MM22-T1T1T1T1 has an external
power supply.
Use undamaged parts.
Relevant for North America:
The device may only be connected to a supply voltage of class 2 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).
For using the device in areas with a risk of gas explosion according to
directive 94/9/EC (ATEX):
Make sure that the device carries the following device label:
II 3G (... followed by additional specifications).
Observe the clause "Special Conditions for Safe Use ..." on the
