Disconnect the fa n from the power supply prior to any work 
on the unit. 
All the electrical connections of the fan must be made by a qualified 
electrician.  
The nominal values of electrical para meters are given on the fan 
manufacturer's label.
Any tampering with the internal connections is prohibited and will 
void the warranty.  

The power supply depends on the fan type: 230V/50 Hz single-phase or 
380V/50Hz three-phase AC voltage.

The fan connections (cables and wires) must be durable, insulated and 
heat-resistant. 

The external lead-in (230V/50Hz or 380V/50Hz)  must be equipped with 
an automatic circuit breaker integrated into the stationary wiring. 
The position of QF external switch must ensure free access for quick 
power-off of the fan.  

The recommended automatic breaker nominal current and conductor 
sections are given in Table 3.

The power conductor section is 1.5 mm. 
However, the conductor section selection shall account for the maximum 
permissible wire heating which depends on the wire type, its insulation, 
length and installation method (i.e. overhead, duct layout or inside the walls).

The trip current shall be consistent with the current consumption of the 
unit as given in Table 2.

The fan connections shall be made on the terminal block mounted inside 
the terminal box on the fan casing in strict accordance with the electrical 
connection diagram and terminal designations. 

The label with terminal designations is inside the terminal box.
The QF automatic switch is not included in the delivery package and is 
installed by the user.

The fan wiring diagrams are given on Fig.4 and 5. 
Connect the fan to the power mains as shown on Fig.6.
