3TRANSPORT AND HANDLING
It is recommended to pay attention and care during the handling and transport of linear actuators
not to damage mechanical parts and / or accessories and to prevent risks for the personnel in
charge of this activity.
The packaging must be lifted and moved with care and in a safe way.
For lifting and transporting the linear actuator, the push rod must be in retracted position.
Lift the actuator from the housing and outer tube, supporting the motor during transport.
DO NOT lift the actuator from the push rod and / or the motor.
The ball screw inside the actuator is NOT self-locking. Never lift the linear actuator upright from
the push rod as the actuators could be back driven by its own weight.

6.2 Servo actuator limit switches: mounting and positioning
Servo actuators have two or more slots on the aluminium profile to fit the stroke limit switches. The profile
shape is in compliance with ISO 15552 standard. Following drawings show these arrangements.
Both type of sensors can be fitted inside their slot from the top.
FTV sensor mounting
The FTV sensor consists of two elements held together by a screw: the sensor FTV
and the fixing bracket. After fitting the sensor and the bracket from the top, it is
necessary to align them and partially screw the fixing screw. The group can then be
moved along the slot in the desired position and finally locked by tightening the
screw.
FCM sensor mounting
The FCM sensor is fitted from the top; when in the required position, they can be fixed by turning clockwise
the screw until stroke end.
FTV Sensor
