4 INFORMATION ON OPERATION AND
USE

4.1 Basic Instructions

Please observe the instructions on the intended use, de-
scribed in 1.1, as well as the safety instructions described
in 1.2 to 1.12.
If the rated current of the drive motor is exceeded during op-
eration, check whether the mains voltage and frequency cor-
respond with the device data.
The device can only be restarted after the cause of the fault
has been identifi ed and eliminated following surge protec-
tion, such as triggering of the motor protection switch, trig-
gering of the PTC evaluation device with motors fi tted with a
resistor sensor or frequency converter surge protection with
FU-ATEX applications.
With blowers that cannot be used over the whole character-
istic curve, the motor can be overloaded if the system resist-
ance is too low (too high power consumption). Restrict the
fl ow rate in this case using a throttle valve built into the pres-
sure or air intake side.
The blower must not be subjected to any vibration stress or
impact force.

4.2 Frequency Converter Operation

A wide speed setting range is possible using a frequency
converter, whereby there is only a small speed difference be-
tween the idle running and the maximum load of the blowers
depending on the load.
Please note the instructions in chapter 3.3.
Failure to observe this information leads to a disproportion-
ate increase in the motor current and the drive motor does
not reach the rated speed.
Warning!
To avoid personal damage, destruction of the
blower or motor overload, a higher frequency
(speed) than the frequency (f
20
rating plate must never be set on the converter
otherwise the motor may be overloaded or the
blower destroyed due to the increased speed. It
also not allowed to set a "Boost" at the converter
because a strong heating of the drive motor
would be the resolution.
It is absolutely essential that you observe the
installation and safety instructions described in
the respective operating or application manuals
provided by the frequency converter supplier to
guarantee a safe and trouble-free operation.
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 mm
comply with the EN61800-5-1 standard.
Operation and connection to public power supply net-
works:
Most frequency converters are designed to operate on indus-
trial grids. If the converter is connected directly to and oper-
ated on a public grid, then additional interference suppres-
sion measures, such as a mains choke, must be built into the
mains feeder. For further information, refer to the converter
manufacturer's specifi cations.
5 MAINTENANCE INFORMATION
5.1 Repair and Replacement of Parts of Elektror ATEX
Products
When using spare parts and accessories for explosion pro-
tected blowers made by Elektror, be sure to apply and ad-
here to the EU regulations or applicable national regulations
for explosion protection. Within the territory of the Federal
Republic of Germany, these especially include the require-
ments set forth in TRBS 1201-3 and §14 (6) of the BetrSichV.
Within the EU, all member states have set in force corre-
sponding legal requirements and regulations which must be
adhered to.
Outside the European Union, the buyer, distributor and user
must adhere to the laws, regulations and statutes relating to
explosion protection, applicable at the operating site of the
respective Elektror ATEX product.
We recommend that you turn in your Elektror ATEX blower
for repair or replacement of parts to our production facilities
in Waghäusel.
We will inform you of the results of our competent analysis
of the technical condition including recommendations for the
best procedure to be followed. You will also be informed what
can be done to restore the product to an optimum conditio.
