3.4 Handling
To keep people safe or prevent damage to property,
use compliant handling equipment that is in a good
condition.
The casing must be lifted at the 4 lifting lugs.
Use slings with a length that is at least double the
height of the casing. Make sure that the slings do
not rub against the motor cowl or the electrical
accessories.
If in doubt, detach it to avoid any damage.
3.5 Casing assembly
The support surface that will support the base of the casing must be as at as possible (sealing frame or
upstand supplied on demand). A seal of foam or similar material (not supplied) is recommended between
the support surface and the base of the casing. A maximum incline of 2.5° is tolerated between the motor
axis and the vertical axis (see diagram below).
Let available space for maintenance operations (§ "6. MAINTENANCE", page 41).
2,5°
Make sure that the support is adapted to the weight
of the whole machine and its various accessories.
Attach the casing at the Ø20 holes provided for
this purpose. You are advised to use a LL washer.
Any screws that are not properly tightened may
make noises and cause harmful vibrations. Once
the machine has been correctly set up, make sure
that the motor turbine is able to rotate freely without
any friction or noise. Vibration isolating devices are
available: KUBZ 05.
Detaching and re-assembling casing panels
The smooth side panels are easy to detach by

4. ELECTRICAL CONNECTION
4.1 Preliminary precautions
Electrical connections must be set up by qualied sta󰀨. Electrical connections will be set up in accordance
with the Standard NF C15-100 which indicates that the motor must be protected by an all-pole mechanism
whose opening clearance is 3 mm per contact. Do not forget the earthing connection.
In the event of use in smoke extraction, please refer to Standard NF S 61-932 for connection and
installation. Use high-temperature cables of the CR1-C1 kind. The cable must be protected against UV
radiation. Please note that cables and electrical accessories must be dimensioned according to Article
433-3 of Standard NF C 15-100: "the section of the conductors of the line is determined by a permissible
current equal to 1.5 times the rated current of the motor". No thermal protection device is permitted on the
smoke extraction circuit.
Furthermore, the cables must be protected against any mechanical stress when they are routed if the
connection is established on the terminal box of the motor or on the proximity switch of the casing.
For the purpose of comfort, the motor must be protected by an adapted magnetothermal protection
mechanism.
This electronic commutation motor cannot be directly supplied by the electrical grid, at risk of
being irreparably damaged. The power supply must be realised by the controller.
The unit running and stop must be realized using Start/Stop controller inputs, according to wiring
choice done at §"5. COMMISSIONING AND SETTING", page 14.
Do not stop the unit by switching o󰀨 directly the main electrical supply.
WARNING: use a voltage tester before you undertake any operation.

5. COMMISSIONING AND SETTING
5.1 Preliminary precautions
Before starting fan, make sure that the electric motor and impeller assembly rotate freely and that there
is no object likely to be ejected by the turbine. The protection housings must be fastened to roof fan to
prevent any accidental contact with rotating parts.
The machine should be attached to its support before power is applied.
Switch on just an instant to check the turbine’s rotating direction.
WARNING: The impeller rotating direction must correspond to each speed in the direction indi-
cated by the arrow on the product. A centrifugal backward fan unit with an impeller that does not
rotate in the right direction still creates a owrate and a low pressure in the duct. An incorrect ro-
tating direction can lead to an abnormal overheating of the motor, resulting in its destruction and
cancelling our manufacturer’s warranty.
If the rotating direction is incorrect, cut o󰀨 the electrical power supply, make sure no power is present,
Contact after-sales service. Do not modify wirings, as this might seriously damages the unit.
While running, make sure that the motor’s absorbed current is not more than 10% above the name plate
indicated current .
Once the roof fan is installed and the tests successfully completed, present the main points of the opera-
tion and maintenance manual to the user, and explain:
• How to start up and shut down.
• How to change the operating modes.
Then hand over to the user the technical manual of the roof fan and the mounted accessories so that he
can keep it handy to consult it at any time.

15/44 NT-50907601-KUBAIR-F400-ECOWATT-AN-191025
5.2 Controllers
The ECM motor controller controls this motor according to an adjusting potentiometer on the controller, an
external 0-10V signal or a set point given by Modbus BMS .
The Modbus BMS connection, present as standard, allows you to adjust the ow rate set point or pressure,
and to read the controller registers to nd out the state of the roof fan.
5.2.1 Controller terminal block
Unscrew the plate on the front of the controller (Torx
T20 screwdriver).
5.2.2 Adjustment potentiometer
Adjustment potentiometer
5.2.3 Fault correction
In the event of a fault, restarting operation after switching o󰀨 the power for 5 minutes may allow the con-
troller to reset. A fault relay allows us to identify the main causes of faults on the controller.
Connection of the relay:
For sizes 355/400/450: Controller - Terminals 4, 5, 6.
For sizes 500/630/710: Controller - Terminals 17, 18, 19.
Regardless of the principle of operation of the roof fan, the relay operates in the following manner:
STATE OF THE UNIT State of
the relay** Compacto Invento
"Normal" operation (COP, CAV, VAV) NO 5-6 18-19
Supply cut o󰀨 NC 4-5 17-18
On / O󰀨 switch open - the wheel is stationary but power is on to the controller. NC 4-5 17-18
Loss of phases* - possibility that during a loss of phase the wheel continues to turn. NC 4-5 17-18
*If the control unit detects a fault more than once, notably a phase problem twice, the roof fan will not restart automatically. (**)
NO.: normally open, NC: normally closed.
Switch o󰀨 the power supply for 5 min and restart the roof fan. If the problem persists, it is possible to
identify the nature of the problem in the registers of the Modbus. The controller operating manual is avail-
able for more information on www.vim.fr.

• reading of registers (state of the casing).
Recommendation for ModBus connection.
The protocol used is ModBus RTU 485. It is imperative to respect the rules of the art of a ModBus
network for reliable communication.
You can connect up to 32 controllers on the same segment.
We recommend using twisted shielded cable with the following features :
• Max speed : 10 Mbps,
• Max : 6 dB,
• Impedance : 120Ω (at 100 kHz),
• Capacity between conductors : 52.2 pF/m,
• Section 24 AWG / 0.22 mm².
The maximum recommended length is 1000 m for a segment for a speed of 19200 baud.
Derivations must be at most 40 m. The ModBus communication cable must be separated from the power
cable.
The shielding of the cable must be positioned in the wire rope clamp present in the controllers.
Terminations are required at each end of segment (120Ω + 1 nF).

5.3 Operation for smoke extraction
The KUBAIR®F400 ECOWATT® is approved for extraction of hot gases and smoke in the event of a re.
This mode of operation is automatic and does not require any setting: In the case of extraction of gas at a
temperature > 200°C, the roof fan will automatically switch to high speed with its internal thermal protec-
tions inhibited.
The smoke extraction mode must be triggered manually with a BDRA type control unit.
The CAV/VAV/COP modes are no longer accepted.

5.5 KUBAIR®F400 ECOWATT® Single-phase - VAV variable ow rate control
VAV - Slaving to an external signal
In variable speed operation, the controller pilots the speed of the roof fan linearly. The controller will vary
the speed of the roof fan between 200 rpm (min. speed), and its maximum speed in proportion to the signal
sent by the external sensor. If the display is present on the roof fan, it will show you the ow rate in m3/h.
The speed adjustment can be done in di󰀨erent ways:
• by the potentiometer integrated in the controller,
• by a CVF ON/OFF + variation remote control,
• by an external 0-10V output,
• by a BCCA switch (0/LS/HS with adjustable LS),
• by a VRPZ voltage variator (allowing operation 0 / LS / HS with adjustable LS and HS),
• by ow rate control by Modbus BMS.
VAV - Regulation according to the deviation between the set point / external measurement
During operation at variable speed, the controller regulates the speed of the roof fan according to the set
point-measurement deviation. The set point is adjusted with the potentiometer built into the controller or
a CVF type external control. If the display is present on the roof fan, it will show you the ow rate in m3/h.
