Frequency converter
Design
Frequency inverter with variable output voltage and frequency, specially designed for
the operation of centrifugal fans with induption motors. Due to the use of modern power semiconductors it is possible to achieve a speed of revolution with high efficiency.
Switching frequencies up to 16 kHz can be set with all types. If the highest switching
frequencies are required (for example for reasons of noise reduction), the maximum
output current is decreased, in which case the performance category should be
specially checked.
The overall package includes the frequency inverter, filter for class B (for
residential and commercial uses) as well as a control unit.
General Performance characteristics
Motor protection feature for motors with thermistor temperature sensors, adjustable
accelaration and deaccelaration ramps, minimum and maximum rotation speeds,
fixed rotation speeds, trapping switch during operation, programmable inputs and
PI-controller (MM420 and MM430 only), RS485 serial interface as well as a detailed
operating instructions. Caution about combination with isolators (ESH)! Special EMCaction can be necessary, furthermore do not switch during operation, overvoltages
can destroy the switch and the motor-winding.
Performance range G110 1AC 230V (for single-phase AC supply)
0.25 kW to 2.2 kW rated motor power, 200 V to 240 V 10 % single-phase AC, 47 Hz
up to 63 Hz, three-phase current output 3×230 V AC, protection class IP20.
Permitted ambient temperature during operation: -10 °C up to +40 °C.
Performance range MM420 3AC 400V (for three-phase AC supply)
0.55 kW to 11 kW rated motor power, 380 V to 480 V 10 % three-phase AC, 47 Hz
up to 63 Hz, three-phase current output 3×400 V AC, protection class IP20. Permitted ambient temperature during operation: -10 °C up to +50 °C. The interference
suppression filter required to comply with the EMC basic interference suppression
standard EN 50081-1 (residential and commercial uses) is integrated into the package
as substructure option. Power choke to comply with EN 61000-3-2 as additional
component.
Observe performance reduction when using high clock frequencies!
Performance range MM430 3AC 400V
(for three-phase AC supply)
15 kW to 250 kW rated motor power, 380 V to 480 V 10 % three-phase AC, 47 Hz
up to 63 Hz, three-phase current output 3×400 V AC, protection class IP20.
Permitted ambient temperature during operation: -10 °C up to +50 °C. The interference suppression filter required to comply with the EMC basic interference suppression standard EN 50081-1 (industrial applications) is partially integrated. In order to attain EMC requirements Class B a frequency inverter without filter should be selected.
The appropriate EMC-B filter is then required as an additional component.
Observe performance reduction when using high clock frequencies!
The indicated ratings of the units are made for a quick selection. The exact dedication
of an inverter in this catalogue is made by taking into account of the max. admitted
current at a pulse frequency of 4 kHz. It is important to know that at higher pulse
frequencies the supplied current of the inverter will be decreasing, with the possible
consequences of having to select a larger inverter unit. Also longer feed lines or additional radio frequency filters may lead to the choice of a larger inverter size.
The selected frequency inverters (G110 und MM420) are units contains the
frequency inverter (as shown in the following tables) with the matching interference suspression filter (Class B) and a control panel. A further component
is the line choke which is available as an accessorie. For more information the
available frequency inverters are shown in the following tables.

Motor protection unit
Motor protection unit EUM 33
Motor protection unit for three-phase current motors (standard motors) without thermal contacts.
Design
Plastic casing in protection class IP55, permissible ambient temperature +40 °C,
40 Hz up to 60 Hz, frontal operation, for wall mounting. Motor protection unit for singlespeed, non-variable speed three-phase current motors without thermal contacts.
Function
The motor protection units must be adjusted on site to the trigger current. If the
preset trigger current is exceeded, the device disconnects the motor from the mains
supply via a thermal overload release. Pressing the “on key” causes the unit to turn on
again.
All motor protection units EUM33 are also suitable for the protection of EExe-motors
(PTB-Prüfung Gesch-Nr. 3.35/386.3060). They must however be mounted outside of
explosion endangered areas, since they are not themselves designed with explosion
protection.

Description
Direct driven centrifugal fans / TEM/REM / Description
Safety
The fans are designed for installation in equipment and as standard are not equipped
with protective guards.
They should not be put into operation before all protective devices are fitted
and connected!
Protective measures must be carried out as set out in DIN EN ISO 12100 "Safety of
machinery - Basic concepts, general principles for design".
If the application of the fan allows free access to the inlet and discharge apertures,
safety devices must be put in place on the fan in accordance with DIN EN ISO 13857!
Suitable safety guards are available as an optional extra.
Performance data
The performance curves of the fans are determined at the plenum test rig according
to ISO 5801, measured in installation "B".
In the diagrams of all series, the total pressure increase pF and the dynamic pressure
in relation to the flange crosssection at the discharge pd2 are represented in dependency on the volume.
For closer determination of duty same unit performance curves (parabolas) are contained in the diagrams.
The static pressure increase psF with a connected discharge flange can be determined according to the following relation:
All data are valid for the source density r1 = 1.2 kg/m3.
Sound
The noise measuring and evaluation is conducted according to DIN 45635-38 ”Noise
measurement in machines: fans”.
In the diagrams the A-weighted sound power level of the fan is given on the performance curves as the emission size.
The “A” weighted sound power level are identical for fan intake (LWA7) as well as for
fan discharge (LWA4).
The A-weighted sound pressure level LpA7/6 at a distance of 1 m at fan Inlet or discharge can be approximay determined by the following formula:
The sound power levels in the individual octavos can be taken from the electronic
catalogue ”proSELECTA II”.
Media
The series of centrifugal fans, with single inlet are designed for the use in air handling
and ventilation installations.
The fans are suitable for conveying air and other non aggressive gases. The temperatures admitted for the fluid are from -20 °C to +60 °C.
Motors
Standard motors of wellknown brands, type of protection IP55, thermal class F, are
used. During commissioning and maintenance the detailed instructions provided by
the motor manufacturer (type plate/motor operating instructions) must be followed,
this also applies to the motor protection devices required onsite. The motors are
equipped with PTC resistors/temperature sensors as standard. Motors with integrated frequency inverters may be supplied on request.
Electric connection
The centrifugal fans are delivered ready for installation.
The motor terminal box can be accessed easily.
Electric installation must be carried out according to the applicable provisions in
compliance with local regulations. A terminal board circuit diagram showing correct
connection is enclosed with every motor.
Updated circuit diagrams are also available online at www.nicotra-gebhardt。。ｃｏｍ.
In case of operation with frequency inverters, always follow the respective operating
instructions!

Direct driven centrifugal fans / TEM/REM / Description
Explosion protection according to ATEX
Fans for use in explosive atmospheres must comply with EC Directive 94/9/EG
(ATEX 95). Equipment in Group II (all applications except mining) is categorised in
accordance with the required degree of safety for designated use in equipment categories 1, 2 and 3. Depending on suitability, a distinction is in addition made between
G (gas, vapours) and D (dust).
Harmonised European standards and national guidelines must be observed. Equipment in class 2 and 3 is not subject to compulsory specifications nor to type testing.
The manufacturer declares conformity with the EC directive.
For the standard designs of our fans, the following ignition sources are essentially to be considered:
Hot surfaces, e.g. due to heat of friction or seizure of a bearing or due to blockage
of an impeller
Rubbing-, grinding- or beating sparks, e. g. as a result of contact of the impeller
with stationary components
Sparks resulting from discharge of electrostatically loaded, non-conducting omponents, e. g. of plasticpanels, surfaces with strong layer thickness.
Preconditions for operating:
In the proximity of the motor, the temperature limits -20 °C and +40 °C must not be
exceeded.
The temperature limits of -20 °C und +60 °C for the flow medium must not be
exceeded. If the temperature of the flow medium should exceed +60 °C on the
pressure side, then the fan must be switched off!
The fans may only be employed with a horizontal shaft.
The fans are to be protected against the falling-in or sucking-in of foreign objects.
Protection guards must be ordered separay as an accessories.
On the machine plate the max. permitted fan speed is indicated.
Fans for operation in ex-hazardous areas are marked as such on the machine plate
and they are accompanied by an EU conformity declaration and with operation and
maintenance instructions
The operation and maintenance instructions have strictly to be observed.

Why should FFU’s be used in cleanrooms?
Benefits which count …
... Redundancy
With hundreds, or thousands of individual FFU’s in a facility,
the loss of one or more units does not jeopardise the integrity of the room.
... Flexibility
As the needs or uses change in a facility, the units can be
exchanged with lay-in lights or blank panels. For facilities
with lower classification, upgrades can be obtained by
simply adding additional FFU’s. When a computer controlled
management system is installed, units or clusters of units
can be remote controlled to operational needs.
... Cost effective
Use motors with the lowest power consumption available.
With complete controllability of each and every FFU (via
control and monitoring software) use just as much of power
as necessary for your process.
... Negative plenum
The negative plenum design draws recirculation air from
the plenum itself. If there are any leaks, they migrate to the
negative plenum and NOT the cleanroom.
... Salvageability
FFU’s are fully salvageable as stand alone units.
Monitoring
Clean room processes call for
the most advanced ventilation
technologies that match to the
specifications of the building
infrastructure:
