Safety Instructions
Intended Use
The linear actuator is a laboratory device as
defined by DIN EN 61010-1. It is intended to be
used in interior spaces and in an environment
which is free of dirt, oil and lubricants.
In accordance with its design, the linear actua-
tor is intended for positioning and adjusting of
loads at different velocities. The linear actuator
is not intended for applications in areas in
which a failure would present severe risks to
human beings or the environment.
The intended use of the linear actuator is only
possible when completely mounted and con-
nected and only in combination with a suitable
controller.
The linear actuator may only be installed, ope-
rated, maintained and cleaned by authorized
and appropriately qualified personnel.
Installation
There is a risk of minor injuries from crushing or
of property damage between the pusher and a
fixed part or obstacle.
X
Use protective structures to keep limbs
away from areas in which they could be
seized by moving parts.
X
Maintain safety distances according to DIN
EN ISO 13857.
X
Mount the linear actuator so that the moti-
on of the pusher is not hindered by objects
in the workspace.
If the linear actuator is vacuum-compatible,
attention must be paid to cleanliness.
X
Only touch the linear actuator with pow-
der-free gloves.
X
If necessary, wipe the linear actuator clean.
Overtightening the mounting nut or the moun-
ting screws can damage the mounting shaft and
hinder the motion of the pusher.
X
Observe the maximum torque for mounting
(see manual).
The torque that occurs when the tip is replaced
can damage the linear actuator.
X
Avoid torques to the pusher.
A cable break leads to a failure of the linear
actuator.
X
Install the linear actuator so that the cable
is not bent or squeezed too severely during
operation.
Heat produced during operation can affect your
application.
X
Install the linear actuator so that your
application is not affected by the dissipating
heat.
Start-Up
Operating voltages that are too high or incor-
rectly connected can cause damage to the
linear actuator.
X
Only use compatible controllers.
X
Observe the operating voltage range of the
linear actuator (see manual).
X
Observe the correct pin assignment (see
manual).
The linear actuator can carry out an uninten-
tional motion when being connected to the
controller.
X
Before connecting the linear actuator,
check whether a macro is defined as the
start-up macro in the controller and cancel
the selection if necessary.
Lateral forces that act on the pusher impair the
motion of the pusher and increase wear on the
drive components.
X
Avoid lateral forces on the pusher of the
linear actuator.
High accelerations can cause damage to or con-
siderable wear on the mechanical system.
X
Stop the motion immediately if a controller
malfunction occurs.
X
Approach the end of the travel range at low
velocity.
Unsuitable settings made to the servo-control
parameters can impair the performance of the
linear actuator.
X
Only use the default parameters for the
first start-up.
X
Individually adjust the operating parame-
ters (see controller manual).
Mounting the Linear Actuator
NOTICE!
Damage from incorrect mounting.
X
Observe the safety instructions in
the „Installation“ section.
X
Do not exceed the maximum permis-
sible torque of the mounting nut or
the mounting screws (see manual).
Mounting with grub screws
If the linear actuator is to be mounted to the
groove of the mounting shaft, at least one grub
screw must be used.
1. Make at least one threaded hole in the me-
chanical mounting across from the groove
(for dimensions, see manual).
2. Insert the linear actuator into the mechani-
cal mounting.
3. Screw a grub screw into each threaded hole
so that it engages in the groove.
4. Check that the linear actuator is affixed
firmly.
Mounting with mounting nut
1. Insert the linear actuator into the mechani-
cal mounting.
2. If necessary: Stick a flat washer or spring
washer onto the mounting shaft.
3. Clamp the linear actuator with the moun-
ting nut.
4. Check that the linear actuator is affixed
firmly.

Changing the Tip
NOTICE!
Torques on the pusher can damage the
drive.
X
Avoid torques on the pusher.
The supplied tips make it possible to realize
different mechanical connections to a load.
1. If necessary (see manual): Use an open-end
wrench to hold the pusher by the wrench
flats.
2. Unscrew the tip to be replaced.
3. Screw in the new tip by hand.
4. If necessary: Remove the open-end wrench
from the pusher.
5. Check that the tip is affixed firmly.
