7.5.1.2 Connection of several FMAs to a unit outside the air stream:
ƒ Distribution unit:
- The distribution unit  is used for systems with at least 2 EC FMAs.
- For the wiring, refer to the diagram inside the unit.
- Two types of control are possible:
Installation: 0/10V or ModBus card
1: Power dividers
2: Earth terminals
3: Disconnect switch
4: 0/10V or ModBus card
7.5.2 AC MOTORS fan (plug fan and impeller)
ƒ Electrical connection:
- A - Machine without variator and without proximity switch:
To be connected directly to the terminal box for the motor(s).
Europe zone: Pursuant to regulation 1253/2014 concerning the implementation of directive 2009/125/CE, an asynchronous
motor may not be used without a speed variator.
- Remove the cover from the motor unit to make the connection.
- Insert and connect the cables in accordance with industry practice.
- Before switching on for the first time, correctly reposition the motor unit cover.
Motor electrical connection:
The connection must be made by a qualified person following the diagrams below, in accordance with those supplied with the
motors.
Warning: the motors
Check the supply voltage, the input current and the protection calibration.
For motor output of 5.5 kW or more, we recommend Y/∆ starting to limit the starting current (Id/In) and reduce wear on the
transmission.
ƒ Dual voltage type motor with Y, ∆ coupling (6 terminals):
230/400 V motor
- Supply voltage 230 V, connection (∆): diagram A
- Supply voltage 400 V, connection (Y): diagram B
400/700 V motor
- Supply voltage 400 V, connection (∆): diagram A
- Supply voltage 700 V, (for P≥5.5 kW), connection (Y): diagram B.
