2. Safety
2.1 General safety instructions
MAGFORCE linear drives have been designed, built and inspected for safe operation in
accordance with state-of-the-art technology the standards (Machine Directive 89/392
EWG, Low Voltage Directive 73/23 EWG and EMV Directive 897 336 EWG) and have left
the factory in a perfect and safe state. Despite this, the drive can be dangerous to per-
sons and objects if they are not fitted and operated correctly. Therefore these Operating
instructions must be read in detail and understood and the safety instructions must be
taken note of.
In the case of incorrect use and for incorrect purposes, the manufacturer rejects any
kind of liability and guarantee.
The linear drives described in Chapter 1 are machine parts in terms of the Machine
Directive. They are only to be installed in machines and systems by specialist companies
and institutions taking into account the valid guidelines and statutory regulations.
Especially the following directives and the resulting laws and standards must be taken
into consideration:
Ÿ 89/ 392 EWG EU machine directive
Ÿ 72/ 23 EWG EU low voltage directive
Ÿ 897 336 EWG EU-EMV guideline
Depending on the use of the machine or system into which the linear drive is to be
installed, additional product or product group specific guidelines and standards may
apply. It is the machine or system manufacturer who is responsible for ensuring that
these guidelines and standards are complied with .
Linear drives may not be operated after they have been into the machine or system until
all requirements specified in the EU machine directives regarding safety and health have
been fulfilled.
In terms of EMV guidelines, linear drives are classified as supplied parts for the exclusive
use and processing by specialist companies. The measures required to comply with the
MEV Safety regulations must be taken by the manufacturer of the end product taking
into consideration the fitting conditions, wiring, control and switching and must be
checked in accordance with its use.
2.2 Use in accordance with the regulations
MAGFORCE linear drives are only to be used for lifting purposes.
Every other type of use is not permitted. Reconstruction and changes to the linear drives
or the electrical installation is not permitted.
Only original replacement parts and accessories from SKF may be used.

2.4 Safety at work
• Depending on the location of where the linear drive will be used, pro
tective devices must be installed which protect persons from crush injuries. Please read
the relevant insurance liability and product specific regulations.
• If this drive is used in lifting gear or in applications which might endanger persons,
please contact SKF. In these cases, special safety nuts or secured fork heads which
are available as an option must be used.
• The safety nuts which are available optionally are only effective in one direction of
load. This must be taken into account when ordering and installing the drive.
• If the linear drive is in operation, persons or objects must not be positioned in the
vicinity of the stroke area of the linear drive.
• Electrical connections at the client's site must be designed so that in the case of a
power failure and subsequent supply of power, the drive cannot start up again.
• Assembly and connection lines as well as technical data (load limits, operating times,
...) must be adhered to precisely in all aspect for the linear drives. Changes must be agre-
ed with SKF beforehand.
• Without additional cooling measures, the housing of the linear drive can reach a tem-
perature of 130°C. If there is a danger of persons or inflammable objects coming into
contact with the housing, a touch guard must be fitted.
• The inner limits must not be used as stroke limits. This can destroy the drive.
The drive is not always self-locking. Static loads resting on the drive can cause the drive
to move. Check data sheet and specity brake where necassary.
• Connection, wiring etc. may only be performed by specialist electricians or trained
personnel taking into account the applicable standards and safety regulations.
• Before opening the device (connection case), the mains supply must be disconnected.
• No technical changes may be made to the drive.
The instructions regarding safety at work
must be taken into account.

2.5 Technical progress
The manufacturer reserves the right to adapt technical data to the progress in technolo-
gy without making any special announcements. SKF will gladly provide informati-
on regarding possible changes and extensions to the Operating instructions and whether
they are up to date.
2.6 Guarantee
Assuming that the operating conditions have been adhered to and no prohibited chan-
ges have been made to the interior of the device and the devices show no mechanical
damage, the manufacturer grants a guarantee of 2 years and a maximum of 3 years
after delivery on all mechanical and electrical components
3. Assembly and installation
3.1 Assembling the linear drive
The linear drive is fitted to the rear trunion and the fork head (see Fig. 2). We recom-
mend that an adapter piece and fork head are used to fix to the push tube. Rotation of
the push tube during operation is not permitted. The load to be moved may only act
centrally on the push tube, lateral forces must be avoided.
The drive can be mounted in any position, but it must not be tilted.
Fixing regulations: Use fixing bolts with a shear strength of at least 1.2 times the nomi-
nal force of the drive. The maximum static load is 6 kN.
1 Front fixing hole 2 Push tube
3 Rear fixing hole 4 Fixing bolt (not included of delivery )
WARNING!
The load to be moved must always act
centrally on the connecting rod. Forces
acting from the side must be avoided.
When using in areas which could endan-
ger people, a special securing nut and
secured fork heads must be used in
order to prevent the load moving in the
case of overloading and the supporting
nut breaking (see also Chapter 2.4
Working safety).
The securing nut is only effective in one
direction. This must be taken into consi-
deration during installation.

4. Electrical connection
4.1 Electrical connections for linear drives
The motors must be connected in accordance with Fig. 4. The direction of rotation is
reversed by polarity reversal via relays or push buttons.
Direct polarity reversal must be avoided due to the inertia force and to protect the swit-
ching elements.
The key or switch must return to the zero position automatically if the appropriate ope-
rating element has been enabled. At the stroke limits, the motor must only meet with
resistance briefly before cutting out. Otherwise the use of stroke limit switches is neces-
sary. Stroke limit switching is
available as an option.
WARNING!
The installation must be performed by
trained electricians. Before installation,
the mains supply to the devices must be
disconnected!
Before connecting, please note the type
designation DSP, ASM, WSP, FSX, DSK
and DSX and the appropriate connecting
information (see rating plate).
The electrical cables must be positioned
such that they cannot be damaged by
crushing, bending or tension. The cable
entrance must be checked for tightness.
If the operating time is exceeded, the
thermal-switch is triggered:
- switch motor off,
- secure against accidental
switching on.

4.3 Setting the terminal-position shutdown (option)
The optional terminal-position shutdown is mounted on the protective tube. It can be
rotated to adapt it to the local conditions (see Fig. 5).
The desired stroke is set by positioning both trip cams on the bar (see Fig. 5.1).
You should bear in mind the switching distance of the limit switches.
The terminal-position shutdown is set at the factory to the maximum possible stroke
(=1..2 mm before the limit stop).
The desired limit switch adjustments must be made before assembly.
Move the linear actuator up and down several times, and make any fine adjustments as
necessary.
Procedure:
• Mount the hood (1) of the terminal-position shutdown after completing the electrical
installation (see section entitled "Electrical connection") and once you have under
stood and checked the mechanical function of the terminal-position shutdown.
• The connection terminals carry mains voltage!
• Then check that the motor is running in the correct direction.
• If necessary, change the phase sequence / polarity.
• Extend the actuator completely.
• Loosen the trip cam (2) at the grub screw (3) and push it to your desired lower
terminal position.
• Now fasten the trip cam (2) using the grub screw (3) for the lower terminal position.
• Move the actuator to the desired lower terminal position.
• Proceed in exactly the same way for the upper terminal position with trip cam (4).
• Move the linear actuator up and down several times, and make any fine adjustments
as necessary.
Warning
Risk of electric shock!
Installation work must be carried out by
properly qualified electricians.
Close the housing before setting the trip
cams.
The terminals are live!

Operating instructions
5. Operating / Starting up
After the mechanical and electrical installations have been performed correctly, the drive
can be started up. By applying short switch-on impulses you can see whether the drive
is rotating in the correct direction. It is important that it rotates in the correct direction
especially if the drive is equipped with a stroke limit switches device as otherwise a fault
is possible.
The linear drive is controlled using push button or relays (Up / Down).
The push button or switch must return to the zero setting automatically when the res-
pective operating element is enabled.
Once the drive has reached the stroke limits the motor must switch off. Direct polarity
reversal of the direction of rotation must be avoided to treat the motor with care.
The load stated on the rating plate and in the section listing technical data may not be
exceeded; the drive could be damaged if overloaded.
6. Brakes
6.1 Free-wheel brake
As an option the actuators can be supplied with a free-wheel brake. The direction of the
operation must be defined by the customer.
Way of function:
Free-wheel brake brakes when the pushtube retracts. I.e. the pulling load will not be slo-
wed down.
Free-wheel brake brakes when the pushtube extends. I.e. that a pushing load will not be
slowed down. These free-wheel brakes have a direct effect on the motor axis and will be
transmitted over the worm-gearing on to the spindle shaft.
ATTENTION: free-wheel brakes have an effect in one direction only!
6.2 Friction brake
A friction brake is permanently active, i.e. it has an effect in both directions.

Operating instructions
8. Maintenance and care
The linear drive is equipped with a special nut and sufficient lubrication reserve and the-
refore requires no maintenance.
The service life of the drive depends on the operating location and the operating period.
The push tube must be cleaned and lubricated from time to time. Defective motors must
be repaired by SKF or by one of their authorised dealers.
For customer specific applications where the path-force-cycle ratios and environmental

9. Trouble shooting and rectificati
on of faults.
Repairs must be performed by SKF or by one of their authorised dealers. Therefore
please return a defective drive.
However, first check all electrical connections and mechanical components for possible
defects.
If the Drive nut is broken, the actuator can continue to work under light loads on the
safety nut. A low power output and high power consumption point towards this type of
damage. Regular operation is not permissible in this case. The device must be repaired at
the manufacturer.
10. Technical support
If faults occur during the operation or guarantee period which cannot be rectified by
trained electricians, please contact our internal experts.
