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.
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
Note
: The shielded ground wire of the twisted pairs lines is connected to the
back panel as a conductor.
Beware of possible short circuits when connecting a cable section with
conductive shield braiding.
