General
Wiring of the ventilator should only be performed by a qualified electrician.
The ventilator and motor specifications
are listed on the ventilator’s type plate.
Max. fuse rating = 13 Amp.
At start-up and during the initial
adjustment of the ventilator, it is important
to control the direction of rotation of the
motor and to check the motor current does
not exceed the manufacturer’s
recommended rated current for the motor
(to avoid damaging the motor).
Repair
switch
EXHAUSTO A/S stresses that according to the Machine Directive
(Appendix 1), a repair switch must be fitted in the fixed installation of
the ventilator.
The switch must …
• be lockable or positioned in plain sight in the immediate vicinity of the
ventilator.
• be able to disconnect all poles from the electrical supply.
– contact distance of at least 3 mm in each pole.
• set up as a power supply isolator in accordance with standard EN 60
204-1.
The repair switch is not supplied by EXHAUSTO.
1.4.1 Ventilator without frequency converter
Wiring Wiring should be done as stipulated in the electrical drawing in the door of the motor's
terminal box (Fig. 7).
BESB250-4-1,
BESB315-4-1
All one-phase ventilators are voltage regulated.
The motor is fitted with a thermal cut-out. The thermal-cut out is factory installed and
wired in series to the motor's power circuit (electrical diagram in the terminal box fig. 1).
Use the circuit diagram (Fig. 2) if a manual reset is required after a thermal cut-out,
where the thermal cut-out is used as a contact in the control circuit.
The motor has overload protection.
BESB500-4-3 The ventilator has a three-phase motor, which cannot be voltage regulated.
NB The motor does not have a thermal cut-out and should have a correctly rated
circuit breaker installed.
The motor can be regulated using an installed external frequency converter max. 50 Hz.

Diagram
Leakage current When operating the FC-motor frequency converters have a leakage current of less than
3.5 mA. The leakage current must be earthed, as there is a risk of the motor becoming
live.
Earth leak circuit
breakers
Only Type-A earth leak circuit breakers can be used with one-phase FC motors, as
required by IEC755 (Amendment 2). The circuit breaker activates when faulty current is
registered with DC component. These circuit breakers are marked with:
Dimensioning of
the neutral
conductor.
Multiple one-phase BESB with FC installations in a shared network with a common
neutral, require special dimensioning of the neutral, as the current is not a pure sine
wave.
Example For example if three FC motors are installed, sharing 3-phases, the neutral current is the
sum of the three motors’ current.
Existing
installations
If you are fitting motors to an existing installation, check that the neutral conductor can
cope with the resultant load.

Flexible
connections
The ventilator must always be connected to the duct system with FLF, to avoid any
chance of vibrations being transmitted. The spigots on the ventilator are standard-sized
and fitted with rubber seals.
To achieve maximum performance with minimal energy consumption the ventilator
should be connected to the duct system with the specified lengths of duct before and
after the ventilator. The FLF connections must always be fitted as shown.
Sound pressure
level
The ventilator is fitted with sound dampers suited to the requirements of the operating
area. The sound pressure for all types of BESB is less than 70 dB (A). The duct system
is insulated against sound propagation, heat loss, fire and condensation.
No Duct A protective net (accessory) with mesh size of 12 mm must be fitted if the ventilator is
not fitted to a duct. It should be noted that:
• such fittings result in a pressure drop in the system
• Air volume measurements cannot be measured correctly when there is no duct
fitted on the suction side

EXHAUSTO provides a two-year factory warranty on the box ventilator, valid from
invoice date. The motor in an EXHAUSTO box ventilator is fitted with special ball
bearings that are lubricated and sealed, and maintenance-free. Any replacement of
these bearings should be carried out by technicians from EXHAUSTO SERVICE or
similarly qualified professionals.
The ventilator must be cleaned at least once a year. To clean the ventilator:
• Switch off the power supply to the
ventilator using the repair circuit
breaker. Open the service door when
the fan has stopped running.
• Wash the ventilator housing and the
centrifugal impeller thoroughly with
soap and water. The parts must be
dry and the service door closed
before the ventilator is restarted.
• The centrifugal impeller can be
dismounted and cleaned. Measure
the exact position of the impeller on
the axle before removing it. The
factory position of the impeller is
shown on the cabinet behind the
service door. If there are weights on
the centrifugal impeller do not remove
them.
• Check that cooling air can move
freely through the motor cover.

Lækstrøm FC-motorens frekvensomformer afgiver under drift en lækstrøm som er mindre end 3,5
mA. Lækstrømmen skal ledes til jord, da der ellers er risiko for, at motoren bliver
spændingsførende.
Fejlstrømsrelæer Hvis der anvendes fejlstrømsrelæer til de 1-fasede FC motorer skal de være af type A i
henhold til IEC755 Amend. 2 som afbryder, når der registreres fejlstrømme med DC
indhold (pulserende jævnstrøm). Disse fejlstrømsrelæer er mærket med:
Dimensionering af
nulleder
Ved installation af flere 1-fasede BESB med FC i net med fælles nulleder, stilles der
særlige krav til nullederdimensionen, da den optagne strøm ikke er sinusformet.
Eksempel Installeres f.eks. 3 FC-motorer fordelt på 3 faser, er nulstrømmen lig med summen af de
3 motorers strømme.
Eksisterende
installation
Tilsluttes motorerne en eksisterende installation, skal det undersøges, om nullederen
kan klare belastningen.

Lækstrøm FC-motorens frekvensomformer afgiver under drift en lækstrøm. Lækstrømmen skal
ledes til jord, da der ellers er risiko for, at motoren bliver spændingsførende.
Der kan forekomme en lækstrøm på op til 150 mA.
For at overholde EN50178 skal aggregatet tilsluttes forstærket jord.
Fejlstrømsrelæer Hvis der anvendes fejlstrømsrelæer i f. m. BESB500-4-3FC skal de være af type B i
henhold til IEC755 Amend. 2 som afbryder, når der registreres fejlstrømme med DC
indhold (pulserende jævnstrøm) og glatte fejlstrømme.
Disse fejlstrømsrelæer er mærket med:
Fejlfinding Se vedlagte instruktionsbog for frekvensomformeren (ligger i elektronikboksen).
Når fejlen er afhjulpet, kan fejlmeldingen på frekvensomformeren afstilles ved at afbryde
forsyningsspændingen midlertidigt indtil lysdioden slukkes.
