bearing damage.
– Never attach additional components to
the outer diameter of the device.
Static indetermination
NOTICE!
Risk of material damage due to static
indetermination or centrifugal force.
The device is not suitable for absorbing
forces, e.g. static indetermination or centri-
fugal force.
– Only use the device in the environment
as approved by the manufacturer and
for the agreed purpose.
Static overdetermination
NOTICE!
Risk of material damage from static
overdetermination.
Static overdetermination is generated by
screwing the rotor and stator to the sur-
rounding. If no suitable measures are
taken to prevent the resultant forces, this
installation can cause the destruction of
the device.
– Only use the device in the environment
as approved by the manufacturer and
for the agreed purpose.
Incorrect pressure connection
NOTICE!
Risk of material damage due to incor-
rectly connected pressure lines.
Connections which are established incor-
rectly can cause damage or flooding on
the device, shaft seals may burst under
the pressure, penetrate through the device
and into adjacent machine compartments.
– Adhere to the markings for the connec-
tion bores on the housing and clearly
identify the connections using the infor-
mation in the drawings included with
delivery.

Leaks
NOTICE!
Risk of material damage to the sur-
rounding structure from leaks.
The primary and secondary sealing sys-
tems of a rotary feedthrough are subject to
wear. This can lead to leaks.
– Safeguard sensitive surrounding struc-
tures, such as bearing units, coils on
electrical machines etc., from contact
with leaked liquids.
– Replace wear parts in line with the
maintenance intervals.
Water and food
NOTICE!
Risk of material damage from transfer-
ring food.
Device designs made of steel and with
nickel-plated components are not suitable
for use with food.
– Do not transfer food through them.
– If necessary, consult the manufacturer.
6.3 Preparations
Personnel:
nSpecialist staff
nElectrician
1. Switch off the machine or system in which
the device should be installed and secure
against switching on again. Block possible
mechanical movements.
2. Stop the supply of all media, electrical cur-
rent and disconnect the data lines and
secure them to prevent it from being
switched back on.
3. Allow hot components to cool down as
necessary.
4. Check the entire installation environment of
the device to ensure that it is isolated from
the voltage and depressurised. Switch off
and secure adjacent live parts.
5. Provide surrounding machine parts, e.g.
drive motors, shaft and spindle bearings,
with constructional protection from media
leaks which may be caused by the failure of
the device.
