
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 54.
 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.
