Safety and Standards
2. Safety
2.1 Safety notes
• Only properly qualied personnel are permitted to perform mechanical and electrical
installation on this product. Properly qualied personnel are familiar to mechanical or electrical
installation work and that have the appropiate qualications for their jobs.
• Read this manual and any other available documentation before working on the equipment.
that the actuator is or shall be a part of.
• Keep strictly to the data in this manual and on the name plate on the actuator and never
exceeed the performance limits stated herein.
• Never work on the actuator or its installation with the power on.
• Never unplug any cables or connectors during operation or with power on.
• Immediately stop to use the actuator if it seems faulty or broken in any way and notify an
appropiate person so that corrective actions can be taken.
• Never try to open the actuator as that will compromise the sealing and the function of the
actuator. There are no serviceable components inside.

4. Installation
4.1 Name plate
The name plate can be found on the actuator housing. It will tell you which model of actuator you have
and its basic performance data. Please study the name plate to see what type of actuator you have
before starting any installation or service on the actuator. If you need any assistance from Thomson,
please tell us the manufacturing date and the deisgnation of the actuator(s) in question.
4.2 Terminology
a. rear adapter c. housing e. extension tube
b. cable outlet d. cover tube f. front adapter
4.3 Operation environment
The operation temperature range is between -25 to +40° Celcius (-13 to 104° Fahrenheit). The protection
degree against the ingress of water and particles is IP67.
Installation
Min. -25° C (-13 F) Max. +40° C (+104° F) IP67

4.4 Mechanical installation
Always install actuator so that the force of the load acts in the center of the extension tube and the rear
adapter and support the mounting pins at both ends (a).
Only mount the actuator to the rear and front mounting adaptors using solid pins (b). The mounting pins
must be parallel to each other both radially and axially.
The actuator can be equipped with an optional anti-rotation mechanism (see Section 5.4 Type
Designation Key) where the moving extension tube is internally restrained from rotating. With this option,
the maximum radial play in the extension tube is 10 degrees (c).
If the anti-rotation option is not selected, for proper function, the application must provide a minimum
restraining torque of 11 Nm between the mounting pins. Otherwise the extension tube will rotate.

Radial play max. 10 °

4.5 Electrical installation
M Actuator motor
S1 Double pole double throw (DPDT) switch
S2 Single pole double throw (SPDT) switch
E Electronic Limit Switches (ELS), optional feature E
F Fuse (supplied by customer)
By switching the polarity of the voltage to the motor the extension tube will change direction (diagram N).
When using the ELS option the direction of the extension tube travel is controlled by switching the COM
(common) ouput to the EXT (extend) or RET (retract) inputs (diagram E).
General notes
• Make sure the leads/cables leading to the motor can handle the maximum motor current.
• Always protect the actuator and the wiring by using a fuse between the actuator and the
power source.
• Never work on the actuator or the wiring with the power switched on!
Standard actuators (N)
• The actuator voltage must be switched off when reaching the ends of stroke or during a
mid-stroke overload to avoid causing damage to the actuator.
• Make sure that the switch can handle the maximum motor current.
Actuators with ELS option (E)
• The actuator will automatically switch off when reaching the ends of stroke or if a mid-stroke
overload occurs.

4.6 Wire cross sections
To avoid malfunction due to voltage drop the cross section of the wires between the actuator motor and the
power source must be of sufcient size. For longer cables than stated in the table calculations based on the
supply voltage, the current draw, the lenght of the cables and the ambient temperature must be done.
