the safety inspector has given his approval for the operation of the installation and that no external
persons are present in the plant area
If envisaged by procedural regulations provided by the operator, minutes have to be taken on the
commissioning work, including the observance of the check list.
5.2 Drive
The fan is driven by an electrical motor which is connected either directly or via a v-belt to the impeller shaft.
Data on the electrical connection of the motor are indicated on the motor’s data plate or in the motor
manufacturer’s data sheet.
When speed is controlled by means of a frequency converter, the maximum rotational speed is limited by
COLASIT to the value indicated on the manufacturer’s plate.
If the frequency converter is not provided by COLASIT, the operator is
responsible for the observance of the maximum rotational speed limit. In this
case, COLASIT does not assume any liability for damage that can be attributed
to exceeding the maximum rotational speed.
5.3
Electrical installations, EMERGENCY - STOP
The electrical installations may only be carried out by an authorised electrician in accordance with the
regulations valid at the site at which the fan is installed.
For the interruption of the power supply, an EMERGENCY-STOP switch is to be provided. It is advisable
that this switch be mounted in the vicinity of the emergency exit.
Please request confirmation from the in-house electrician that the electrical installations were carried out and
tested in accordance with regulations, that all functions have been tested (or simulated) and that the
rotational direction is correct.
Caution
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.
6 Operation
6.1 Safety
regulations
The fan is to be operated according to this manual. In doing so, you will avoid
possible damage.
Supervision
The fan must not be operated unattended as long as it conveys substances,
whose reactions are unknown or if unexpected reactions are to be anticipated.
If the supervision has to be withdrawn for operational reasons, this has to be
reported to the safety inspector and the plant has to be secured in such a way
that no unauthorised manipulation can be carried out. The safety inspector
decides on questions regarding supervision.
