
Supply with DC voltage: 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:
The power supply lines are made up of copper wire.

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 voltage supply connections with a protective conductor
connection: 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.

Shielding ground
The shielding ground of the connectable twisted pairs lines is connected
to the front panel as a conductor.

Beware of possible short circuits when connecting a cable section with
conductive shielding 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.
