Electrical Safety - CIAT MAJOR LINE Manual De Instrucciones

- Controller or thermostat for 3-speed on/off control:
Power up the unit and select the ventilation speed to be modified using the thermostat.
Use the "CIAT speed control unit" accessory supplied as an option to adjust each
speed (rpm) in accordance with the instructions included with the speed control unit.
- With a controller managing a 0-10 V control signal:
The 0-10V setpoint voltage information is issued by the controller itself. Refer to the
operating and configuration instructions supplied by the manufacturer.

Warning: if electrical heaters are used, the lowest speed setting should never be
below 400 rpm.
To prevent any risk of damage, never connect several asynchronous or brushless fan
coil unit motors in parallel for the same thermostat.
IMPORTANT NOTE: BRUSHLESS MOTOR
The electrical connection for CIAT Comfort Units must be made in compliance with
international standard IEC 60364 (Electrical Installations for Buildings). The leakage
current for all our Comfort Units complies with the requirements of standard IEC
60335-2-40 (Household and similar electrical appliances - Safety):
- Complete comfort unit (with electrical heaters) equipped with a multi-speed
motor: maximum leakage current = 2 mA.
- Complete comfort unit (with electrical heaters) equipped with an HEE
motor (Brushless technology): maximum leakage current = 4.5 mA.
Electromagnetic compatibility in accordance with Emission standard 61000-6-3
EN 550141-1, tool class and Immunity 61000-6-1 (Residential, commercial and light
industry class).
Important: the unit's compliance with the above standards does not guarantee the
compliance of the installation as a whole (several other factors not relating to the unit
may be involved).
As a result, the installer must observe the applicable recommendations in order to
guarantee compliance.

Electrical safety:

To ensure user safety, earthing is compulsory.
The installation must be equipped with a device to protect against earth faults.
A disconnect device must be built into the installation between the supply and the
230 VAC power network, and must be easy to access. The disconnect device must
simultaneously disconnect the two poles (live and neutral), and have a distance of
at least 3 mm between the contacts, in compliance with the installation instructions.
The mains power cable must have 3 conductors (blue, brown, green/yellow) and its
cross section and type must comply with the specifications set out by the applicable
EN or IEC standard. Refer to the selection sheet or the name plate to determine the
maximum input current. The cable must be fed into the box via the circular hole fitted
with a protective grommet and secured in the dedicated strain relief.
