1.2 Safety Considerations
Proper and Safe Use of Product
Device Damage Prevention
To prevent permanent damage to the device, proper care should be taken not to exceed published
voltage, current, temperature, and load/force ratings. In addition, proper mechanical assembly and
proper wiring should be verified and safety measures checked before applying power to the complete
equipment package.
Personal Safety
During normal operation the actuator can become hot, especially the appropriately marked electric
motor housing, which is electrically coupled to the actuator. In addition, the case ground of the
appropriately marked electric motor should be tied to an earth ground to prevent the presence of
case voltage.
During normal operation, the actuator rod travels in and out creating a possible pinch point.
Proper guarding and signage must be used prevent entry into possible pinch zones and contact with
hot surfaces. It is highly recommended to display proper safety notices and implement proper safety
measures to prevent contact with hot surfaces.
Handling and Unpacking
When unpacking and handling the actuator, care should be taken not to drop the actuator as this can
damage the connectors, internal electronics, or cause misalignment of the actuator feedback device.
Damage the internal mechanical components may cause poor performance or render the actuator
non-functional. Since this is an electromechanical device, proper ESD measures should be taken to
avoid static electricity from contacting the signal and power lines of the device. as this can damage
the internal mechanical components rendering the actuator damaged or non-functional.
Packing and Transport
NOTE!
Package actuator to prevent damage during transport. Also make sure the actuator is clean, dry and
protected from moisture.
Modifications to the Equipment
WARNING!
The manufacturer takes no responsibility whatsoever if the equipment is modified or if the equipment
is used in any way beyond performance specifications. Unauthorized modifications or changes to the
equipment are strictly forbidden and void all warranties.

Requirement Regarding Personnel
NOTE!
All personnel must be completely informed regarding all safety regulations and the function of the
equipment.
Risk Area and Personnel
When installed, pinch points are generated capable of damaging forces. The risk area surrounding
the actuator must either be guarded or clearly marked, including display signage in accordance with
all applicable national and international legal requirements. The risk area must be protected by a
safety system that stops the equipment if anyone enters the risk area. Personnel who enter the risk
area must be authorized, trained and qualified for the different tasks inside the risk area.

WARNING!
Prior to installation and commissioning of this equipment this Manual and all accompanying
manufacturer documents and manuals MUST be completely read by the appropriate personnel. All
warnings must be given special attention.
4.1 General Operation
RSX series linear actuators function by translating the rotary motion of externally mounted electric
motor into linear motion of the thrust rod using a planetary roller screw mechanism. The travel
coordinates, linear speed, acceleration and force are typically controlled by a servo drive.
The relationship between the rotary motion of the motor and the linear motion of the actuator
corresponds to the following relationships:
Linear Force (N) = [motor torque (Nm)/1000 x 2 x π x reduction ratio x screw efficiency]
/ screw lead (mm)
Linear Force (lbf) = [motor torque (lbf-in) x 2 x π x reduction ratio x screw efficiency]
/ screw lead (in)
CAUTION!
Care should be taken not to exceed the physical travel limits of the actuator. Exceeding the specified
stroke will cause the actuator to reach mechanical end of stroke internally. Although protected by the
end of stroke bumpers, reaching internal end of stroke at speeds and torque greater than those used
to home (less than 25mm/sec and low torque) may physically damage the screw and the internal
components of the actuator.
4.2 Alignment and Side Loading
Alignment of the actuator with regard to the application axis of motion and the direction of the force
is essential to its proper functioning. Misalignment creates side loads on the thrust rod, leading
to rod binding, uneven roller nut loading and premature wear of rod seals, leading to excessive
heat generation and reduced service life of the actuator. RSX series actuators must not be used in
applications where side loading occurs. Loads must be aligned with the line of motion of the thrust
rod. Where necessary rod alignment couplers may be used.
Mechanical Installation of RSX Actuators4

4: MECHANICAL INSTALLATION
4.3 Mechanical Installation
1. Open the crate and remove packaging material
2. Carefully remove linear actuator from the crate *Consider the weight of the actuator.
Depending on the configuration, the actuator can weight over 227 kg (500 lb)
3. Visually inspect the actuator for damage
4. Notify the carrier of any shipping damage immediately
5. Move the actuator to its position.
6. If the actuator is mounted in a vertical or inclined position include safety measures to
prevent load from falling in the case of screw failure or loss of power
7. Ensure sufficient clearance around the actuator to allow for airflow and cooling
8. Follow installation mounting instructions for each configuration.
4.4 Lifting and Moving
CAUTION!
Special care must be taken when lifting and moving the RSX actuators. Depending on the size
and configuration RSX actuators can represent heavy and awkward loads. Lifting equipment with
appropriate capacity must be used, and safe hoisting practices must be employed.

method.
a.Sonic tension meter
i. Enter the mass, width, and span from the table above into the tension meter.
ii. Test the belt using the
manufacturers recommendations
iii. Compare the span tension to
the target in the “Span Tension Force”
b.Force deflection method
i. At the center of the span,
measure the force required to deflect
the belt the distance called out in
the “Deflection” column in the table above. The measured force should fall within the
deflection force tolerance noted in the “Deflection Force” column.
1.Ensure one pulley is free to rotate.
2.The deflection force needs to be evenly applied across the entire belt width. Use a piece of
steel or angle iron across the belt width and deflect the belt evenly.
