The product packaging is suitable for handling and lifting with
warehouse equipment.
Check the integrity of the packaging before handling.
• The product must be stored in a dry environment protected from
severe weather conditions
• Storage temperatures must be between -20°C and +80°C
• The product must always be handled with the rod completely
retracted.
• The product may only be lifted at the points shown in the figure.
• It is forbidden to use the rod for lifting the Series 3E
electromechanical cylinder.
When installing the component, make sure that there is no danger due
to possible uncontrolled mechanical movements.
The Series 3E electromechanical cylinder can only be installed by
specialised personnel or by trained personnel under the guidance and
supervision of qualified personnel.
Before starting the installation, check the direction of the rotation to
make the rod extend and refract.
It is strongly reccomended not to paint the Series 3E electromechanical
cylinder.
Accidental falling and/or crushing of the packaging may compromise the
functionality of the product and cause serious injury to the handler.
• It is forbidden to use the rear end cap to lift the product, in order to
prevent the rod from coming out of the cylinder body due to the
reversibility of the recirculating ball screws.
CAUTION: Vertical or slanted mounting of the Series 3E
electromechanical cylinder, with the rod facing downwards, can be
dangerous. The rod could come out of the Series 3E electromechanical
cylinder at an uncontrolled speed due to the reversibility of the
movement of the recirculating ball screw it contains.
CAUTION: Constraining of the actuator by any accessory must always
be carried out by checking the correct alignment of the accessory to
the final application.
Incorrect assembly with misalignments and/or forcing can
compromise the performance and durability of the actuator.

Installation conditions
The general catalogue of the Series 3E electromechanical cylinder shows
the conditions for correct use and technical information.
Before starting un the Series 3E electromechanical cylinder check that:
• The declared characteristics and performance correspond to those
required;
• It has not been damaged in transit;
• It is installed in such a way as not to create danger to people, things,
property and/or animals;
• It is equipped with the appropriate fixing devices and is firmly fixed;
• Proper use of the assembly configurations is recommended as
indicated below in the manual;
• If is exposed to the action of machine operators, provide special non-
avoidable guards and/or special PPE.
Before setting up the 3E electromechanical cylinder, check that it
functions correctly, if it is to be used in circuits that comply with the
requirements of the ISO 13849-1 standard.
In case of different applications, contact Camozzi Automation S.p.A.
During use, temperature must be between 0°C and 50°C.
CAUTION: Comply with the specified temperatures, protect against
water humidity and attack by corrosive substances.
Install the Series 3E electromechanical cylinder in a location
accesible for maintencance so that it does not create dangers for
maintenance workers.
NO
Loads not allowed
• The Series 3E electromechanical cylinder cannot be radially loaded
on the rod or on the structure.
• The structure of the Series 3E electromechanical cylinder cannot be
used for assembling other components.
For applications of this kind, contact Camozzi Automation S.p.A.
Assembly position
The Series 3E electromechanical cylinder can be mounted in any position:
horizontal, vertical with the rod up, vertical with the rod down, slanted.
Always avoid set-ups in which unexpected movements of the actuators
could be hazardous to surrounding equipment and people.
• The Series 3E electromechanical cylinder has an internal anti-rotation
mechanism but cannot withstand torsion on the rod:
In the case of vertical or slanting installation, the use of self-braking motors
must be allowed to avoid uncontrolled strokes in the event of a drop in
voltage.
CAUTION: It is forbidden to pass through or stop in the work area
of Series 3E electromechanical cylinder.
CAUTION: due to the nature of the Series 3E electromechanical
cylinder the stem is subject to movement.
Provide protective devices for operators in the work area.

cylinder with the clamping brackets as shown in the figure below.
Possible support configurations
The Series 3E electromechanical cylinder can be fixed with the
appropriate supports:
1 - On the front end cap of the Series 3E electromechanical cylinder;
2 - On the housing of the configuration with in-line motor;
3 - On the cover unit in the in-parallel motor configuration.

Assembly of rod accessories
• It is forbidden to subject the cylinder rod to the torsion generated by
the tightening torque of the front accessories.
STEP 1
After having correctly positioned the Series 3E electromechanical
cylinder (1), assemble the half-coupling (2) on the rear shaft of the
cylinder and lock it with the appropriate screw as indicated in the
"Assembling the flexible coupling" section . Then fit the elastomer (3).
