Qualified personnel are familiar with appropriate measures against
these hazards in order to reduce the risk for themselves and others.
Qualified personnel receive training on a regular basis.
National and international safety regulations
Verify that the electrical installation meets local or nationally applicable
safety regulations.
Grounding the device
The device is grounded via the separate grounding screw on the back of
the device.
Use a wire diameter for the ground conductor that is no smaller than
the diameter of the supply voltage connection, however of at least 1.0
mm² (AWG16).
Ground the device before connecting any other cables.
Disconnect the grounding only after disconnecting all other cables.
Shielded ground
The shielded ground wire of the twisted pairs cables is connected to the
front panel as a conductor.
Beware of possible short circuits when connecting a cable section with
conductive shield braiding.
Supply voltage
The supply voltage is electrically isolated from the casing.
Exclusively connect a supply voltage that corresponds to the type plate of
your device.
Every
time you connect the electrical conductors, make sure that the
following requirements are met:
The power supply conforms to overvoltage category I or II.
The power supply has an easily accessible disconnecting device
(for example a switch or a plug). This disconnecting device is
clearly identified. So in the case of an emergency, it is clear which
disconnecting device belongs to which power supply cable.
The electrical wires are voltage-free.
The ground screw on the back of the device is connected to the
protective conductor.
There is a fuse in the outer conductor (AC) or the positive
conductor (DC) of the voltage supply.
Regarding the properties of this fuse:
See “General technical data”
on page 52.
Supply with DC voltage: the fuse is suitable for a DC voltage.
If the neutral conductor (AC) or the negative conductor (DC) is not
grounded: there is a fuse in each of the two wires.
The wire diameter of the power supply cable is at least 1 mm²
(North America: AWG16) on the supply voltage input.
