Chapter 1
Please read this safety information carefully:
Be aware of the following three symbols throughout the user manual:
Warning!
Failing to follow these instructions can cause accidents resulting in serious personal injury.
Recommendations
Failing to follow these instructions can result in the actuator suffering damage or being ruined.
Additional information
Usage tips or additional information that is important in connection with the use of the actuator.
Furthermore, ensure that all staff who are to connect, mount, or use the actuator are in possession of the necessary
information and that they have access to this user manual.
Persons who do not have the necessary experience or knowledge of the product/products must not use the product/
products. Besides, persons with reduced physical or mental abilities must not use the product/products, unless they
are under surveillance or they have been thoroughly instructed in the use of the apparatus by a person who is
responsible for the safety of these persons.
Moreover, children must be under surveillance to ensure that they do not play with the product.
Before you start mounting/dismounting, ensure that the following points are observed:
• The actuator is not in operation.
• The actuator is free from loads that could be released during this work.
Before you put the actuator into operation, check the following:
• The actuator is correctly mounted as indicated in the relevant user instructions.
• The equipment can be freely moved over the actuator’s whole working area.
• The actuator is connected to a mains electricity supply/transformer with the correct voltage and which is dimensioned
and adapted to the actuator in question.
• Ensure that the voltage applied matches to the voltage specified on the actuator label.
• Ensure that the connection bolts can withstand the wear.
• Ensure that the connection bolts are secured safely.
Safety instructions

Page 7 of 80
During operation, please be aware of the following:
• Listen for unusual sounds and watch out for uneven running. Stop the actuator immediately if anything unusual
is observed.
• Do not sideload the actuator.
• Only use the actuator within the specified working limits.
• Do not step or kick on the actuator.
When the equipment is not in use:
• Switch off the mains supply in order to prevent unintentional operation.
• Check regularly for extraordinary wear.
Classification
The equipment is not suitable for use in the presence of a flammable anaesthetic mixture with air or with oxygen
or nitrous oxide.
• Do not sideload the actuator.
• When mounting the LA33 in the application ensure that the bolts can withstand the wear and that they are
secured safely.
• If irregularities are observed, the actuator must be replaced.
Recommendations
• Do not place load on the actuator housing and do prevent impact or blows, or any other form of stress to the
housing.
• Ensure that the cable cover is mounted correctly. Use 3.5Nm torque.
• Ensure that the duty cycle and the usage temperatures for LA33 actuators are respected.
• Ensure that the cable cannot be squeezed, pulled or subjected to any other stress.
• Furthermore, it will be good practice to ensure that the actuator is fully retracted most of the time.
The reason is that there will be a vacuum inside the actuator when it is extended, which over time can lead to
water entering the actuator.
• If the actuator (without integrated controller) is mounted in an application where a mechanical stop prevents the
endstop switches in the actuator from being activated, the actuator must be equipped with an electrical safety
device (current monitoring) or external limit switch.

Mounting guidelines
LINAK®linear actuators are quickly and easily mounted by slipping pins through the holes on each end of the
units and into brackets on the machine frame and the load.
Figure 2
Right WrongWrong Wrong
Figure 1
The mounting pins must be parallel to each other as
shown in Figure 1. Pins, which are not parallel to each
other, may cause the actuator to bend and be damaged.
The load should act along the stroke axis of the actuator
as off-centre loads may cause bending and lead to
premature failure. See Figure 2.
Make sure the mounting pins are supported in both ends.
Failure to do so could shorten the life of the actuator. Also,
avoid applying a skew load on the actuator.
The actuator can rotate around the pivot point in the front and rear end. If this is the case it is of high importance
that the actuator is able to move freely over the full stroke length, both during the development and daily
operation. Please pay special attention to the area around the housing where parts can be trapped and cause
damage to the application and actuator.
In applications with high dynamic forces LINAK recommends not to use the fully extended or retracted position
over longer time, as this can damage the endstop system permanently.

Mounting guidelines
030618/DS
Instruktion vedr. uddrejning af inderrør – LA27 + LA27C
Til salesbackup, brugsanvisning og datablad.
Ved montage og ibrugtagning, er det ikke tilladt at dreje unødvendigt mange gange på
stempelstangsrøret. Hvis øjet ikke er positioneret korrekt, er det tilladt først at skrue
røret i bund (1), og derefter skrue det maksimalt ½ omgang ud igen (2).
• The mounting pins must have the correct dimension.
• The bolts and nuts must be made of a high quality steel grade (e.g. 10.8).
No thread on the bolt inside the back fixture or the piston rod eye.
• Bolts and nuts must be protected so there is no risk for them to fall out.
• Do not use a torque that is too high when mounting the bolts for the back fixture or the piston rod eye.
This will stress the fixtures.
Please note:
The piston rod eye is only allowed to turn 0-90 degrees.
Instruction concerning the turning of the piston rod eye and inner tube:
• When mounting and taking into use, it is not permitted to make excessive turns of the piston rod eye. In
cases where the eye is not positioned correctly, it is permitted to first screw the eye down to its bottom
position, at a maximum torque of 2Nm (1), and thereafter a maximum 90 degrees turn outwards again
(2).
• As the piston rod eye can turn freely, it is important to ensure that the eye cannot rotate if the actuator
is used in a pull application. If this happens, the actuator will be pulled apart and destroyed.
Warning!
If the actuator is used for pull in an application where personal injury can occur, the following
is valid:
It is the application manufacturer’s responsibility to incorporate a suitable safety arrangement, which will
prevent personal injury from occurring, if the actuator should fail.
LINAK’s actuators are not designed for use within the following fields:
• Offshore installations • Explosive environments
• Aeroplanes and other aircraft • Nuclear power generation

Mounting of cables
When changing the cables on a LINAK actuator, it is important that this is done carefully, in order to
protect the plugs and pins. Before the new cable is mounted, we recommend that the socket is greased
with vaseline, to keep the high IP protection and ensure an easy mounting. Please be sure that the plug
is in the right location and fully pressed in before the cable lid is mounted.
Please note that if the cables are mounted and dismounted more than 3 times the plugs can be damaged.
Therefore, we recommend that such cables are discarded and replaced.
Also note that the cables should not be used for carrying the actuator.
We recommend to take some precaution and design the wire connection in a way, where the cable end
is kept inside a closed, protected area to guarantee the high IP protection.
3.Slide the cover onto
the actuator.
The torque of the
cover screw is
approx. 3.5 ± 0.3 Nm
TORX 25IP
1.Unscrew the cover and
remove the two blind
plugs.
2.Plug in the power
cable and/or the
signal cable.

Electrical installation
• To ensure maximum self-locking ability, please be sure that the motor is shorted when stopped.Actuators
with integrated controller provide this feature, as long as the actuator is powered.
• When using soft stop on a DC-motor, a short peak of higher voltage will be sent back towards the power
supply. It is important when selecting the power supply that it does not turn off the output, when this
backwards load dump occurs.
The power supply for actuators without integrated controller must be monitored externally and cut off in case
of current overload.
Recommended fuse for actuators without integrated controller
