1.Please carefully read this operation manual before using this product. We don't take
responsibility for any damage, accident or injury possibly caused by those who didn't
follow these notes to install.
2.Don't disassemble or reinstall this product yourself. Since this product is designed under
structural operation, computer simulation or physical test, it can't be disassembled or
reinstalled without specialist's permission. If there is any accident or damage caused by
self disassembly or reinstallation, we will not take responsibility.
3.If the appearance is damaged before installing or using, please immediately contact us
or an agent.
4.Ensure to read product label or performance specications indicated by the delivery
document before installing linear actuators.
5.Carefully read power supply indicated on the specication label of a control box
before using this product. Moreover, conrm the supplied power complies with product

1.While operating an actuator, don't interrupt the motor operation to avoid failures in
motor or mechanical structure.
2.Please follow the directions and use the nominal voltage of actuator motor with
DC voltage. The supplied DC voltage can provide the maximum current at the
maximum load.
3.If customers use power supplies and controllers themselves, please follow the
current allowed for wire cross-section to install over current protectors (such as
fuse), on the output end of power supplier or the input end of actuator power and
use this over current signal to control actuators, which not only stop movement
or disconnect power supply but also ensure the extension tube of an actuator at
the limit position or under the overload operation can disconnect the power and
provide appropriate control and protection.
4.Unless specially customized, the duty cycle of our actuator should be 10%. The
duty cycle is dened to continuously operate 2 minutes and pause 18 minutes. If
customers operate over duty cycle (10%), please install overheat detection and
prevention devices (as a fan) and use this overheat detection signal to control
actuators to stop movement or disconnect power supply according to control
requirements.
5.If customers don't purchase limit switches, please install the limit switches at the
stroke positions of the extension tube of an actuator yourself and combine that
limiter for power failure on controllers and power suppliers to ensure the power
can be disconnected when the extension tube of an actuator moves to the stroke
and wire position.
6.The actuator is DC driven. When the two input wires of motor power are
exchanged, the extension tube of the actuator will reversely move. Please use
proper controllers and power suppliers while stop. Two input wires of motor power
are short-circuited to provide auxiliary brake. Note that the power of actuator
motor should be disconnected and then short-circuited to avoid short circuit on
power supplier.
7. Don't operate up to the stroke limit if there are no limit switches and controllers
have no overload protection.
8.Don't apply actuators over the maximum load indicated by the specications.
9.If the actuator isn't water-proof, please follow the water-proof regulations.
10.Controller power: AC110V or AC220; the required input power is shown on the
controller's specication tag.
11.Operating temperature: +5°C ~ +40°C (+41°F ~ +104°F).

there is no further movement towards the DC motor while the actuator is
powered on. (Please refer to the gure below.)

2.1. Please ensure that the extension tube is in the "lowest position" before installing
actuators.
2.1.2 External limit switch: For installing an external limit switch, please ensure the
extension tube is in the lowest position before installing an actuator (Please
refer to the gure below.).
※If an actuator doesn't have an external limit switch installed, you must install the
stroke limiter on an actuator yourself. The distance between two actuator limit
switches can't be longer than the stroke of the actuator. And then rotate the
extension tube to adjust the length of an actuator, which can meet the minimum
requirements to install actuators.
※To avoid any wrong movements of actuators, there shouldn't have any magnetic
materials close to external limit switches within 30mm.
2. Installation Guide

A99UE13-1304

2.2.The front and end joints of the linear actuator should be mounted onto two xed
positions on the main chassis. Locations of these xed positions should be chosen
according to the stroke length of the linear actuator (Users must be cautious that the
two-way movement of linear actuator must be smooth and within the stroke length
after installed onto the xed positions). Please ensure that no obstacle exists along
the travel path of the actuator.
2.3.After the xed positions have been selected, install the xtures onto these selected
positions of the main chassis. These xtures are used to x the front and end joints
of linear actuator to the chassis.
2.4.Assemble the front and end joints of the linear actuator onto the two xtures using
xture bolts. Please ensure that the xture bolts are able to rotate freely after this
step is completed. On the other hand, users should also make sure that the xture
bolts would not drop off either during operating or resting period.
2.5.The chassis of linear actuator should be xed in the horizontal direction if it is going
to be operated in this direction and likewise for vertical operation.
2.6.The operation of the linear actuator should be tested manually after the installation
is completed. Users should make sure that:
•The travel distance of the actuator is matching the requirement of the structural
design.

•The upper and lower limit switches are operated normally.
•The motor stops when the extension tube reaches upper and lower limit switch
positions.
If the linear actuator fails to meet any of these conditions, please repeat steps 2.2
to 2.4 until the above mentioned clauses are met
2.7. The entire installation is nished only if steps 2.1 to 2.6 are executed successfully.
2.8. HIWIN Mikrosystem Corp. cannot take any responsibility for any injuries and/or
damages caused as a result of not complying with the clauses of this section.
3.1. Don't use this product to make current transient inversion. If you try to backwardly
move the present extension tube that forwardly moves, you must stop the motor and
apply the reverse current to make backward movement. On the contrary, if you want
the extension tube backward moved to forward, the way to supply current will be the
same as mentioned above.
3.2. Don't use this product with a radial load (Please refer to gures and tables below.)
because an actuator more appropriately applies to take the axial load. If there is
product damage, accident or personal injury caused by improper load, we will not
take any legal responsibility.
