4.4 Mechanical installation
4.4.1 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.
4.4.2 Basic installation considerations
1. Only mount the actuator using the holes in the rear (a) and front (b) adapters. Check the model
number on the actuator product label (section 4.1) and then look at the ordering key (section 7.2)
to nd out your adapter type conguration. See the below drawings and table to nd out the exact
adapter dimensions.
2. Make sure that the actuator mounting position allows access to the cable connector cover plate (c), so
that it can be removed to allow access to the cable connector(s) (section 4.4.4).
3. The cable or cables (d) exit the cable slot at the rear of the actuator housing at delivery but can be
made to leave the housing at any point after the cable connector cover plate.
4. The hand wind input (e) must have enough free space around it to allow it to be operated
(section 4.4.5).
5. If external limit switches will be used, the mounting of the actuator must allow access to the limit
switch slots (f) running along the underside of the cover tube (section 4.4.6).

4.4.3 Mounting orientation and forces
1. The actuator can be mounted in any orientation and handle both pushing and pulling loads.
2. Always install actuator so that the force of the load acts in the center of the extension tube and the
rear adapter.
3. Only mount the actuator to the rear and front adapter mounting holes.
4. Only use solid mounting pins and support them at both ends.
5. The mounting pins must be parallel to each other both radially and axially.
4.4.4 Cable connector cover plate
1. The cover plate is held in place by a screw (M3 with Torx T10 head) that can be accessed through
the hole in the top of the cover plate (a). Keep in mind to mount the actuator so that there is enough
clearance to access the screw with a tool!
2. Once the cover plate is released it needs to be pushed about 20 mm (0.8 inch) in the direction of
the arrow symbol on the cover plate before it can be removed from the actuator (b). The connectors
are a part of the backside of the cover plate and can be accessed once the cover plate is removed.
3. Make sure to put the cover plate back correctly and torque the screw to 1.2Nm (10.6 in-lb) to ensure
that the actuator cover plate and connectors are properly sealed.
YES NO

4.4.5 Hand wind mounting and operation
1. 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!
2. To be able to operate the hand wind, remove the cover plug placed over the hand wind input (a).
3. Next, move the extension tube by turning the hand wind input hexagon socket (b) using a 6 mm male
hexagon key (c).
4. The maximum torque required to move the extension tube at the fully rated actuator load using the
hand wind is typically 4-6 Nm (35-50 in-lb).
Always make sure to switch o󰀨 the power to the actuator before using the hand wind.
Do not apply higher torque than 10 Nm (88 in-lb) to the hand wind input.
Never run the extension tube in to the end of stroke as that may damage the actuator.
Never use any type of drill or power tool to operate the hand wind.
4.4.6 Mounting of optional external limit switches
1. The external limit switches are mounted in the two slots (a) at the bottom of the cover tube.
2. Put the sensor (b) into one of the slots and and lock it at the desired position by turning the clamp
screw 45 degrees (c).
If the sensor is mounted in the immediate vicinity of magnetic components, the
switching characteristics of the sensor may change.

Installation
4.5 Electrical installation
4.5.1 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!
4.5.2 Fuse size
Protect the actuator and the wiring by using a slow blow fuse between the actuator and the power source.
4.5.3 Electrical connections
The actuator is always supplied with a power cable (a). Depending on which control option was selected, it
can also have a signal cable (b). The cable(s) have ying leads in one end for customer connections. In the
other end the cable(s) are integrated in to the cable connector cover plate (c) (section 4.4.4). The plug in
connector allows replacing the actuator without disconnecting the ying leads.
4.5.4 Lead cross sections
To avoid malfunction due to voltage drop the cross section of the leads between the actuator power
cable leads and the power source must be of su󰀩cient size. For longer cables than stated in the table,
calculations based on the supply voltage, the current draw, the length of the cables and the ambient
temperature must be done.
