WARNING
Risk of injury and device damage due to manipulation of the
screws on the device
Manipulation or loosening of the screws on the device or the
optional devices may lead to injury and device damage during
the operations.
Therefore:
• Never loosen screws on the device or the options, except the
transportation screws installed in the mounting bores.
WARNING
Safety hazard caused by wrong screw connections
It is important to respect length, material, quality and tightening
torques of the screws to use or it could have a serious impact on
the safety or operation of the linear actuator.
Details are specified in the following chapters: 6.4.2 Standard
installation procedure (⮑ page 29) and 6.4.3 U-Bracket
assembly variant (⮑ page 30).
6.4.1 Brief description
The linear actuator CAMT must be attached using the
mounting holes provided (refer to chapter ⮑ 11.4 Plans and
diagrams, page 42).
The fastening screws must be used in quantity, quality and
dimensions according to the specifications.
The extension and alignment procedures to ease the assem-
bly of the device as well as the electrical connections are
described in the following sections.
The fig. 17 describes a typical installation of CAMT:
A CPMT telescopic pillar providing the elevation, working to-
gether with two CAMT actuators (1 and 2-DOF) to add axial
and lateral movements.
As all the devices are different, there are different possibili-
ties to install CAMT actuators to telescopic pillars.
The simplest one is to have, at the bottom, the rear attach-
ments directly fastened to the telescopic pillar outer profile
using a standard interface and, at the top, using the existing
mounting brackets to be screwed to the upper structure.
When this is not possible to do, an intermediate plate can be
used to bring the CAMT to the desired location (mandatory
with the U-bracket) plate, that is itself reusing the CAMT
standard fixation points.

6.4.2 Standard Installation procedure
For the following procedure it is assumed that the cardan
system that is the interface between the pillar and the upper
structure (surgery table, procedure chair…) is already at-
tached to the pillar and is securely fixed to be able to as-
semble the actuators in a simple way.
The procedure is therefore the same when a CAMT needs to
be replaced on an already fully assembled final product.
The following sequence then describes a typical way to
mount a CAMT actuator onto a Ewellix telescopic pillar and
is valid for both 1 and 2-DOF configurations. Yet, depending
on the personal configurations, this procedure may be
adapted to every situation.
