 DC voltage Supply: the wire diameter for the input supply line is at
least 1 mm² (North America: AWG16).

The cross-section of the protective conductor cable is the same
size as or bigger than the cross-section of the voltage supply
cables.
 The connection cables used are permitted for the specified
temperature range.

Relevant for North America:
For use in Class 2 circuits, the copper wire conforms to class 1,
60/75 °C or 75 °C.

Make sure that the electrical installation meets local or nationally
applicable safety regulations.

Use undamaged parts.

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 device when the housing is closed.

First connect the ground screw on the back of the device with the
protective conductor before you set up the other connections. When
removing the connections, you remove the protective conductor last.

For supply voltages with protective conductor connections: first
connect the protective conductor before connecting the lines for the
supply voltages.
If your device has a second voltage supply connection of this type:
here you also first connect the protective conductor before connecting
the lines for the supply voltages.

Shielded ground
The shielded ground wire of the twisted pairs lines is connected to the
front panel as a conductor.

Beware of possible short circuits when connecting a cable section with
conductive shield braiding.
WARNING
ELECTRIC SHOCK
Only start connecting the supply voltage if all the above mentioned
requirements are fulfilled.
Failure to follow these instructions can result in death, serious injury,
or equipment damage.
