1.0 General information
1.1 Information on this
manual
This manual provides important information on how to work
with the actuator (also called device or drive) safely and
eciently.
The manual is part of the device, must always be kept in the
device’s direct proximity and should be available for person-
nel to read at any time . All personnel working with the de-
vice must read and understand this manual before starting
any work. Strict compliance with all specied safety notes
and instructions is a basic requirement for safety at work.
Moreover, the accident prevention guidelines and general
safety regulations applicable at the place of use of the de-
vice must also be complied with.
For a better representation of the circumstance of use, the
illustrations used are not necessarily to scale and may vary
from the actual design of the device.
All information and notes in this manual were compiled with
due consideration given to applicable standards and regula-
tions, the present status of technology and our years of
knowledge and experience.
1.2 Explanation of symbols
and signal words
Safety precautions are identied by symbols and signal
words dened on the right hand side of this page.
These signal words indicate the severity of the hazard.
Adhere to these safety precautions and take caution in order
to avoid accidents that may result in personal injuries or da-
mage to property.
DANGER
Indicates a dangerous situation, which
will lead to death or serious personal
injury, if the precautionary measures are
ignored.
WARNING
Indicates a dangerous situation, which
can lead to minor or moderate injury or
property damage, if the precautionary
measures are ignored.
CAUTION
Indicates a dangerous situation, which
can lead to minor or moderate injury, if
the precautionary measures are ignored.
NOTICE
Indicates information considered
important, but not hazard-related (e.g.
messages relating to property damage).
NOTE
Emphasizes useful hints and
recommendations as well as information
for ecient and trouble-free operation.

2.0 Important safety information
2.0 Important safety information
The actuator is assembled and delivered by Ewellix accord-
ing to the ordering key. Modication of the actuator is not al-
lowed in any way. Any modication will void the warranty
and could create a safety hazard. Ewellix disclaims any and
all liability or responsibility for the modied product and for
any claims, demands or causes of action for damage or for
personal injury resulting from modication and/or use of
such product. In addition, if the actuator has been disas-
sembled, misused or altered without prior written authorisa-
tion, warranty will be voided. These installation instructions
are part of the actuator and should be kept together with all
relevant documentation regarding the application in which it
is used.
The following are important safety precautions that must be
followed during installation:
• All electrical installation and maintenance should be car-
ried out by qualied personnel.
• Terminate power supply to the actuator before installation
or maintenance.
• Make sure that the actuator is not under load or in tension
before installation or maintenance.
• Use the appropriate safety equipment when installing/re-
pairing the actuator.
• When connecting the actuator, make sure that the power
supply corresponds to what is required in the technical
specications. See section 5 below.
WARNING
When heavy load and high duty factor is used, motor and
surrounding components can get hot.

3.0 Intended use
The actuator is intended to be used for linear movements
and axial load only, pushing and/or pulling, and intermittent
duty. The actuator is designed to be used in an industrial en-
vironment and is dened as a ”partly completed machine”,
meaning it must be incorporated in a safe way into its i
tended machine.
The actuator can not be used for hoisting people.
3.1 Duty Factors
Permitted load is related to the duty factor and the ambient
temperature where the actuator operates. Consequently,
when load and/or temperature raise the duty factor must be
lowered to prevent the actuator from being damaged.
CAUTION
If the recommended duty factor is exceeded the actuator may be
overheated and damaged.
Duty factor is dened as amount of time running under load
vs. total cycle time.
By using the formula below one can calculate the duty and
determine the risk of overheating.
Duty factor % = x 100
N
N + R
N = running under load
R = rest period
N+R = total cycle time
N
N+R
R
Permitted load for DC actuators at a specic duty factor is
expressed in percentage of maximum dynamic load capac-
ity, ⮑table 1.
Do not permitt the motor surface temperature to exceed
70°C.
CAUTION
Caution, it may take several hours for the actuator to be
overheated.
WARNING
If temperture is permitted to raise uncontrolled the actuator can
eventually cause re.

3.2 Requirements for
correct installation
• Maximum angle between the actuator’s attachment and
the rear mounting attachment must not exceed 30°
(⮑ g. 1).
• The surface to which the actuator is attached must be able
to withstand the force applied by the actuator.
• Ensure that the applied force on the attachments is always
centered on the actuator. (⮑ g. 2).
WARNING
Do not exceed the actuator’s rated load limits. Doing so can
result in serious injury and/or property damage. For technical
data on load limits, see section 5 below.
CAUTION
Avoid running the actuator into the mechanical end position.
Repeatedly running into the mechanical end position may
damage the actuator or shorten its lifespan.

WARNING
• All electrical installation/maintenance should be carried out by
qualied personnel.
• Isolate the power before installation or maintenance. Use the appro-
priate safety equipment when installing/repairing the equipment.
• When connecting this equipment to the electrical supply, make
sure that it corresponds to the one described in the technical
specications.
• For complete installation instructions regarding Ewellix limit

pitches in the CAT-modular range
• The encoder consists of two parts; one rotating magnet on
the motor drive shaft, and one circuit board (PCB) assem-
bled on the motor’s opposite side.
• The rotating permanent magnet has four poles (2N and 2S)
and during one motor revolution, two pulses are generated
in each channel.
• The output signals, channel 1 and 2, are phase-shifted ±90°
• Supply voltage range is from 5 to 24 V DC
• Temperature range is from –20 to +50 °

Daily Check actuator for visible damage
Clean o dust and dirt if necessary
Monthly Check attachments and tighten if necessary
Check that cables are not damaged, replace if necessary
Check optional equipment for visible damage, replace if necessary
Functional check of operation
Every 6 months A few drops of oil should be applied to the adjustment tube
Annually Check labels
Check electrical connections

11.0 Remaining risks
Regardless if the actuator has been installed according to
this instruction some remaining risk excist.
Take note of these points during the lifespan of the actuator:
If any unnormal noise occure stop the actuator directly.
If the actuator has been subjected to excessive load, even
for a short time, be aware of unnormal noise or ”wobbling
movement”.
Do not operate the brake on its own when actuator is under
load.

17
12.0 Destruction/waste
12.0 Destruction/waste
As majority of the actuator is made of steel and stainless
steel some amount of grease/oil can be found inside. The
motor and some assesories, like limit switch and encoder is
considered electrical waste.
Check for local rules and information on how to despose the
actuator and its parts.
Keep this information for future reference. Please contact
your local Ewellix sales oce if you need more information
or spare parts.
Please check ewellix.com for relevant addresses.
