Mechanical installation
General installation safety notes
- Never work on the actuator with the power switched on!
- Do not hold the extension tube while the unit is energized.
- Failure modes of the actuator should be considered to ensure it does not create harm.
Basic installation considerations
- Only mount the actuator using the holes in the front and rear adapters. Identify the model designation of the actuator (section 4.1) and then look at the ordering key (section 6) to find out your adapter type configuration. See the below drawings to find out the exact dimensions.
- Make sure that the actuator mounting position allows access to the connector or cable(s) to allow the actuator to be connected or disconnected when required.
- If the actuator is equipped with the hand wind option, the hand wind input must have enough free space around it to allow it to be operated (section 4.4.6)
Mounting orientation and forces
- The actuator can be mounted in any orientation and handle both pushing and pulling loads.
- Always install actuator so that the force of the load acts in the center of the extension tube and the rear adapter.
- Only mount the actuator to the rear and front adapter mounting holes.
- Only use solid mounting pins and support them at both ends.
- The mounting pins must be parallel to each other both radially and axially.
Restraining torque
The rear and the front adapter must be fixed by a method that can restrain the
torque produced by the extension tube, which for Electrak GX is 11.3 Nm (100
lbf-in). If not restrained in both ends, the extension tube (or the actuator)
will rotate instead of moving. 
Slip clutch
The actuator is protected by a load limiting mechanical clutch which prevents
the motor from stalling at either end of the actuator stroke. It will also
slip at any point along the stroke when the factory-set load limit (1.2 – 1.5
× the dynamic load rating) is exceeded. Stop the actuator imediately if the
clutch is engaged and in case of mid-stroke engagement also investigate the
cause.
Hand wind mounting and operation considerations (optional feature)
- Make sure when mounting the actuator that there is space enough between the rear adapter and any object behind it to allow the hand wind to be operated!
- To be able to operate the hand wind, remove the cover plug placed over the hand wind input.
- Next, move the extension tube by turning the hand wind input hexagon socket (a) using a 6 mm hexagon key (b).
- The maximum torque required to move the extension tube at the fully rated actuator load using the hand wind is typically 1.5 – 2.5 Nm (13 – 22 in-lb) depending of the model
WARNING:
- Always make sure to switch off the power to the actuator before using the hand wind.
- Do not apply higher torque than 5 Nm (44 in-lb) to the hand wind input.
- Stop running the extension tube immediately if the slip clutch (see section 4.4.5) is engaged.
- Never use any type of drill or power tool to operate the hand wind.
Electrical installation
General notes
- Make sure the leads/cables leading to the motor can handle the maximum motor current.
- An emergency stop is recommended to reduce the chance of a crushing hazard.
- Never work on the actuator or the wiring with the power switched on!
Fuse
Protect the actuator and the wiring by using a slow blow fuse between the
actuator and the power source.
The size of the fuse depends on the current draw of the actuator and local
installation regulations and have to be determined on a case-to-case basis.
Power lead cross sections
To avoid malfunction due to voltage drop the cross section of the leads
between the actuator power leads and the power source must be of sufficient
size. The sufficient size is determined by calculations based on the supply
voltage, current draw, length of the cables, ambient temperature and local
regulations. The below tables show our minimum recommendations for a selection
of different lead lengths. However, it is always the responsibility of the
installer to make sure the installation is carried out in accordance with the
local regulations.

Installation of a dc input voltage actuator
Extend the actuator by connecting red to + Vdc and black (yellow)* leads to –
Vdc in the cable. Change polarity to retract the actuator.
When reaching the mechanical end of stroke in any direction the built in slip
clutch will engage and thus stop the extension tube movement in that
direction. The clutch can also be engaged during mid strok due to over load
conditions, see section 4.4.5. Cut the electricty to the motor as quickly as
possible when the clutch have been engaged irrespective of the reason.

M Actuator motor Installation of an one phase ac input voltage actuator
Leads can be either color or number marked. To be able to run the actuator, a
capacitor must be connected between black (1) and red (2) leads. A 115 Vac
actuator requires a 35 μF capacitor, while a 230 Vac actuator requires a 10 μF
capacitor.
Connect black (1) lead to L1 and white (3) lead to N (neutral) to retract the
actuator. Change L1 from lead black (1) to lead red (2) to extend the
actuator.
The anti-coast brake must also be released during motion, which is done by
connecting orange (4) lead to L1.
When reaching the mechanical end of stroke in any direction the built in slip clutch will engage and thus stop the extension tube movement in that direction. The clutch can also be engaged during mid stroke due to over load conditions, see section 4.4.5. Cut the electricty to the motor as quickly as possible when the clutch have been engaged irrespective of the reason.
