Drive
The fan is driven by an electric motor which is connected to the impeller shaft either directly or via a V-belt.
The motor electrical specifications are indicated on the motor’s rating plate or in the motor manufacturer’s
data sheet.
When speed is controlled by means of a frequency converter, the maximum speed is limited by COLASIT to
the value indicated on the manufacturer’s rating plate.
If the frequency converter is not supplied by COLASIT, the operator is
responsible for compliance with the maximum speed limitation. In this case,
COLASIT will not assume any liability for damage that may be attributed to
exceeding the maximum speed.
In the case of motor outputs over 3kW, we recommend the use of a soft starter or a star-delta connection.
4.3
Electrical installations, EMERCENCY STOP
The electrical installations may only be carried out by an authorised electrician in accordance with the
regulations prevailing at the site at which the fan is installed.
To interrupt the power supply, an EMERGENCY STOP switch must be provided. It is advisable to mount this
switch in the vicinity of the emergency exit.
Please request confirmation from an in-house electrician that the electrical installations were carried out and
tested in accordance with regulations, that all functions were tested (or simulated) and that the rotational
direction is correct.
Warning
Do not turn power on or off without prior warning to persons in the area where the
fan is operating. Switching operations must be co-ordinated with other functions
in the working area of the fan.
