C.5
GUARDS AND SAFETY DEVICES
The machine is equipped with safety devices to prevent damage to the operator and to the machine itself.
The machine is equipped with a fixed guard preventing access to dangerous components, such guard
being fixed by means of fastening devices that require the use of tools.
The other moving parts (electric motor) are commercial components already certified by their
manufacturers.
MOVING PARTS
HAZARD
:
It is forbidden to remove or tamper with the guards.
C.5.1
Electrical safety devices (standard configuration with electrical panel)
The machine is equipped with an electrical panel where all the control devices are installed. The
components purchased as part of the electrical equipment are identified, CE-marked and accompanied by
the relevant EC Declarations of Conformity. The machine is equipped with a red emergency stop push-
button on a yellow backplate, positioned on the electrical panel.
ELECTROCUTION HAZARD:
In case of fire in the vicinity of the machine (or on the machine
itself), the use of water or other aqueous/humid extinguishing agents is prohibited, as this
presents a risk of electrocution due to indirect contact.
C.5.2
Safety functions according to the EN13849-1 standard
The safety functions implemented on the machine

For the technical characteristics of the pressure switch, see paragraph L.2
C.5.3
Measures to reduce noise risks
The value shown below refers to the measurements made on a pump produced by Ragazzini S.r.l.,
technically comparable and representative of the machine described in these instructions.
All the other machines produced by Ragazzini S.r.l. have a noise level lower than the one reported.

A-weighted sound pressure level in the workplace
78.6 dB (A)
C.5.4
Measures to reduce extreme temperatures risks
HIGH TEMPERATURE HAZARD
: in case of pumping fluids with a constant temperature
higher than 60°C it is necessary to provide suitable signs or shielding.
C.5.5
Measures to reduce other risks
HAZARD
: The machine is not equipped with
lightning protection; it must be installed in places
protected against this risk.

The definition of safety function is given in the UNI EN ISO 13849-1 standard; a safety function is a function of the machine whose
failure can lead to an immediate increase in the risk related to the machine itself.
3
PL (Performance Level): in the UNI EN ISO 13849-1 standard the
Performance Level
is defined as a discrete level used to specify
the ability of safety-related control parts to perform a safety function under the intended conditions. 5 values are assigned to the
Performance Level, from PL
a
to PL
e
as the risk increases (PL=e > PL=d > PL=c > PL=b > PL=a).
