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 neces-
sary 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

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 LA36 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 3.5 Nm torque.
• Ensure that the duty cycle and the usage temperatures for LA36 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 in the “normal” position. The reason is that there
will be a vacuum inside the actuator if 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.
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 since 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 during daily operation. Please pay special attention to the area
around the housing where parts can be trapped and cause damages 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.

Please be aware that if the LA36 is used for solar applications the actuator must be mounted with the motor housing turned upwards and the wires pointing
downwards.

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.
Warning!
LINAK’s actuators are not designed for use within the following fields:
• Offshore installations • Nuclear power generation
• Aeroplanes and other aircraft

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.

The actuator have a HALL based position system. To ensure the reliability of the position feedback for the
full life time of the product, the actuator must be able to re-calibrate this in the application.
The calibration is performed when the actuator moves in a outwards direction over the area 40-60mm in
one continuously movement without changing speed or stopping.
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.
