Electrical Connection; Speed Adjustment - TERMOTECNICA PERICOLI EOS42-53 Traduction De La Notice Originale

The air circulator can be installed with chains (not included) using
eyebolts included or different frames (not included).
Suspended vertical installation of circulator fan
Suspended inclined installation of circulator fan
The maximum deflection recommended is 12° from the vertical
position. Do not install the air circulator more inclined.
NOTE
The vertical support to which the fan will be secured at heights
must have suitable characteristics of strength and stability to
support the weight of the fan and its induced vibrations.
The installer must identify supports having these characteristics
and decide whether they are suitable.
It is forbidden to install the fan on mobile supports, such as
doors or shutters, having strength and stiffness characteristics
not suitable for the purpose.
The company is not in any way liable for damage to property
and/or persons caused by installations of one or more fans on
supports not suitable for the purpose.
WARNING
Avoid any possible obstruction of the holes located on the lower
part of the wallhousing, which guarantee the correct drainage
of the water.

6.4 ELECTRICAL CONNECTION

WARNING
The power supply connection must be made by trained qualified
personnel in compliance with safety regulations currently in force
in the country in which the equipment is being installed.
Before attempting to connect to the mains supply, power down
the power supply line by opening the main switch.
If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified persons in
order to avoid a hazard. In case it is necessary to replace the cord
please follow the connections shown in the wiring diagram in the
end part of this manual.
1. The fan is supplied with no electrical actuating and control devices.
2. The label placed under the motor cable outlet indicates the type of
supply voltage for which the motor has been configured.
3. Check that the power supply available at the installation location,
correctly provides the required voltage and frequency values.
4. The installer must provide a control panel that complies with the
requirements of International Electrotechnical Commission standard
IEC 61439 and proper wiring that complies with IEC 60204 and
IEC 60364.
5. The following power system protection devices must be installed:
• Safety lockable isolating switch
• A Miniature Circuit Breaker (MCB) (correctly-sized referring to the
motor nameplate data) and a possible Residual Current Device
(RCD) (to be assessed depending on the system configuration).
• A start/stop switch
• An emergency stop button with mechanical lock and manual
reset.
6. It is necessary to correctly size the cables in relation to the motor
nameplate data, their length and to the installation conditions.
7. The machine shall be properly connected to Earth via a dedicated
cable in such a way as to create an equipotential bonding circuit that
is effective against the risk of electrocution. The choice of whether to
install an RCD which will intervene if there is a discharge to earth is
left to the installer (reference standard IEC 64-8).

6.5 SPEED ADJUSTMENT

The fan motor speed can be controlled by means of suitable
frequency converters.
If frequency converters are used, in order to ensure that the
machinery complies with Electromagnetic compatibility (EMC)
requirements replace the cable and the cable gland supplied with
shielded symmetrical cables and EMC cable glands (i.e. cable glands
providing 360 ° bonding between the cable shield and the motor
housing).
You also need:
• to use shielded symmetrical cables and EMC glands along the
entire line between the frequency converter and the machine, for
example on the converter, possible junction boxes, safety switches,
motor etc...;
• do not exceed the motor/propeller rotation speed indicated in the
technical data table;
• set the converter so that the speed can be regulated within the two
limits:
- maximum speed - indicated in the technical data table;
- minimum speed - greater than or equal to 50% of the rated speed.
• the design and sizing of the electrical system are delegated to the
installer or to a deputy; all work must comply with the rules in force
in the destination country.
• Comply with the provisions laid down in the frequency converter
manufacturer's installation manual.
