-Replace the fuse.
Make sure that fuses are replaced only using fuses of the same type, see Chapter 3.2.
-Reconnect the junction box to all power sources.
4.5 Cable gland
The cables have to be fed into the device via glands to ensure leak-tightness. Cable
diameters of 5…9.5 mm are suitable for gland M16.
The cable wires are connected to the terminals inside the device.
NOTICE
Property damage is possible.
If a cable gland is not used, it must be sealed with a supplied locking pin.
NOTICE
Property damage is possible.
Regularly check the tted cable gland for tightness and re-tighten it, if necessary.
4.6 Installation of a cable
NOTICE
Material damage is possible.
Do not guide the screen (4) into the device!
The cable shield (4) must be connected in the metal sleeve (6) of the cable gland.
Before, during and after installation, make sure that the sealing ring is seated
correctly.

interface and the PR 6024/68S junction box.
5.2 Data and supply cables
The PR 6124/xxD data cable must be used to connect the PR 6024/68S cable junction box
to the device, max. length: 300 m.
The PR 6124/xxP power cable must be used to connect the PR 6024/62S power supply to
the PR 6024/68S cable junction box, max. length: 200 m

5.4 Equipotential bonding conductor
NOTICE
It is especially important that the ground is connected correctly to the components
and the cable junction box.
You must also ground the device separately and ensure the power supply is properly
shielded against the eects of lightning. Simply connecting the protective grounding
conductor is not enough!
If the installation is not carried out according to our instructions, this voids the
warranty. In particular, the entire installation, including the power supply, must be
suciently protected against lightning.
In Ex areas, equipotential bonding must be established to avoid any compensatory
currents between the individual conducting system components.
