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.
