Note!
The following times apply for the respective
device motor output class (see rating plate) with
run-up/expiry as well as speed changes in order
to to avoid high component loads and faults in
the converter operation:

A uniform run-up and expiry must be guaranteed within the
run-up and expiry times.
No speed changes must occur during operation that exceed
the speed change during run-up and expiry.
Protection by residual current circuit breakers (FI-circuit
breakers):
The current IGBT frequency converters inherently produce
leakage currents > =3.5 mA. These leakage currents can
lead to false alarms in systems that are fused using a 30 mA
FI-circuit breaker.
In the event of a fault, residual current can also leak as direct
current via the protective conductor. If protection is required
on the supply side by means of a FI-circuit breaker, it is im-
portant that an FI-circuit breaker is used that is sensitive to
universal current (type B). The use of an incorrect FI-circuit
breaker other than type B can lead to death or serious injury
in the event of a fault. The protective conductor must be de-
signed to connect twice via isolated terminals or via a protec-
tive conductor cross-section with a minimum of 10 mm2 Cu
to comply with the EN 61800-5-1 standard.
Operation and connection to public power supply net-
works:
See 3.5
4.3 Hydraulic Motor Operation
The run-up and expiry times as well as the speed changes
speci
fi
ed in 4.2 should be noted when operating with hydrau-
lic motors.
Free-running hydraulic motors should be used to guarantee
a smooth run on.
5 MAINTENANCE INFORMATION
Wearing parts are subject to the recommended maintenance
intervals (see 5.1 to 5.4 ). The service life of wearing parts
(ball bearings and
fi
lters) is dependent on the operating
hours, loading and other in
fl
uences, such as temperature,
etc.
Measures as well as the maintenance and servicing itself
must only be carried out by appropriately quali
fi
ed persons
who undergo regular training. The following must be ob-
served in addition to the operating instructions of the respec-
tive device as well as the regulations and recommendation
for the complete system:
Inspection and maintenance intervals:
The owner should determine the cleaning, inspection and
maintenance interval depending on the operating hours,
loading and operating conditions.
Immediate inspection and maintenance:
In the event of vibrations, oscillations and a reduced air output.
Note!
Repairs must be carried out by the manufacturer.
In the case of repairs; we assume no liability for
changes or the replacement of components by
third parties.
5.1 Ball Bearings
Note!
The fans from Elektror are equipped with sealed
deep groove ball bearings, which do not require
relubrication.
Note!
Check the ball bearings during servicing and
prior to recommissioning.
Operation is only permitted with
fl
awless ball
bearings!
Note!
In the event of frequently starting up and shutting
down, premature replacement of the bearings
will be required. Determining the time for repla-
cing the bearings is the sole responsibility of the
maintenance and servicing personnel, who must
make a safety judgement.

Ball bearing change recommendation
- Prior to reaching the minimum service life
- 30 months following delivery at the latest
- Check after 6 months’ storage time; change if necessary
5.2 Seals and Radial Shaft Sealing Rings
Sealing components and radial shaft sealing rings should be
replaced for safety reasons at least at every maintenance
at which the sealing elements were opened, removed or
changed in any other way.
5.3 Fine Filters
The extent of contamination on the
fi
lter mats should be
checked at regular intervals depending on the operating/am-
bient conditions. i.e. the permeability of the
fi
lters must be
guaranteed by the owner.
5.4 Cleaning/Inspection Opening
There is a high risk of injury on the inside of the device due to
rotating parts during operation. Decommission the device in
all cases and wait until all moving parts have stopped before
opening, reaching in or inserting tools into the device. Secure
the device reliably against it being accidentally restarted dur-
ing the entire period.
