2.3 Safety devices

In the process of designing and building the fan, the manufacturer adopted the necessary technical solutions to ensure
compliance with fundamental safety requirements: the object of the risk reduction process was to ensure that the operator
can use the fan in safety. The machine is provided with protection devices of fixed type and is fitted with an actuator for
the emergency stop function.

Fixed guards

The fixed guards are solidly fixed to the structure of the machine and cannot easily be eluded: the guards are fixed with
systems which require the use of tools for dismantling.

WARNING

Do not start the fan with fixed guards removed: the guards can only be removed with special tools,

by specialized and trained personnel and with the system stationary (emergency system activated and electricity
and hydraulic fluid isolated). At the end of maintenance operations, the guards which were removed must be

replaced correctly.

Position of guard

Type of guard

Notes

Intake side of fan

Guard of fixed type
made of metal mesh.

Dimensions and positioning in accordance with the instructions in the
standard UNI EN 13857. Removable only by means of special tool.

Outlet side of fan

Guard of fixed type
made of metal mesh.

Dimensions and positioning in accordance with the instructions in the
standard UNI EN 13857. Removable only by means of special tool.

Emergency stop function

The machine must be equipped at the installation stage with an electrical panel, on
which must be installed an actuator for the emergency stop function, which when
operated brings dangerous movements to a halt by isolation of the power supply: the
button must be mushroom-shaped and coloured red, provided with mechanical
restraint and released by turning.
