Protection by residual-current-operated circuit breaker
(FI circuit-breaker):
The present IGBT frequency converters produce discharge
currents of >=3.5 mA due to their design principle. These dis-
charge currents can lead to unwanted tripping in systems
protected by a 30 mA-FI circuit-breaker.
If a fault occurs, fault currents can also discharge through the
PE conductor as direct current. If protection is needed on the
supply side by means of an FI circuit-breaker, then an ACDC
sensitive (type B) FI circuit-breaker must be used. Use of an
FI circuit-breaker other than type B can cause death or seri-
ous injury if a fault occurs.
To meet the EN 61800-5-1 standard, the PE conductor must
be duplexed and routed through separate terminals or have
a cross-section of at least 10 mm² Cu.

5 INSTRUCTIONS FOR MAINTENANCE

Wearing parts are subject to the recommended maintenance
intervals (refer to 5.1 to 5.4). The service life of wearing parts
(ball bearings and fi lters) depends on the operating hours,
the load and other infl uences, such as temperature, etc.
Maintenance and servicing may only be performed by per-
sons with the necessary expertise and regular training. In ad-
dition to the appliance's operating instructions and the regu-
lations and recommendations for the system as a whole, the
following points should be observed:
Inspection and maintenance intervals:
The operator must set the cleaning, inspection and mainte-
nance intervals himself according to operating hours, load
and operating conditions.
Immediate inspection and maintenance:
The blower must be inspected immediately if vibrations or
reduced air fl ow are observed.
Note!
Repairs must be carried out by the manufacturer.
We cannot accept any liability for repairs carried
out 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.

5.2 Seals and radial shaft sealing rings
Sealing elements and shaft sealing rings must, for safety rea-
sons, always be replaced after maintenance work involving
opening, removing or otherwise modifying sealing elements.
5.3 Micro-fi lters
The degree of clogging of the fi lter mats must be checked at
regular intervals in dependence on the conditions of use or
ambient conditions and any applicable environmental protec-
tion guidelines. This means that the user is responsible for
ensuring that the fi lters are permeable.
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.
Also make sure that no other dangerous situation can arise
when restarting after a standstill, e.g. as a result of a power
failure or blockages.
Cleaning or maintenance must not lead to damage or modi-
fi cations to the device and its components that would infl u-
ence safety or health protection and, for example, impair the
balanced state of the impeller.
When starting up the blower, make sure that all tools or other
foreign objects have been removed from inside the device
and that all covers and protective grilles have been attached
correctly.
6 SAFETY RELATED INFORMATION
ON TAKING OUT OF OPERATION AND
REMOVAL
The disconnection of all electrical connections and any other
electrical work in connection with decommissioning must
only be carried out by a qualifi ed electrician.
The device should be dismantled only when all rotating parts
have come to a standstill and cannot be restarted.
The guidelines set out in 2.1 Transport and Handling must be
observed when dismantling and removing it.
Treat the device as industrial waste when disposing of it.
The device parts are made of recyclable material, such as
aluminium, (stainless) steel, copper and plastic. However,
there are components that need special treatment (e.g. fre-
quency converters). The statutory national and local disposal
and recycling regulations must be observed.
