cause damages to any parts or devices. This also applies, for example, to the case of a
broken toothed belt (if existing).
The linear actuator must only be used in areas that are not accessible to persons during
operation.
If the linear actuator is used in areas accessible to people, it must be installed in such a
manner that no one can be endangered during operation.
1.4.3. Identifying Residual Dangers and Hazardous Areas
If there are still residual dangers present to persons or property from the linear actuator in
spite of operating it in a safe manner, the user must make reference to these residual
dangers through signs and written rules requiring appropriate procedures.
The following safety signal words are used:
Danger!
Indicates that an imminent hazardous situation may lead to death or serious bodily harm if
not prevented using appropriate safety measures.
Warning!
Indicates a potentially hazardous situation which, if not avoided using appropriate safety
measures, could result in serious or minor injury.

Use only transport equipment with sufficient lifting capacity. When using ropes, make
certain they are not twisted or knotted. If you are using more than one rope, all the ropes
should be equally taut.
When transporting the ETH with a forklift, establish a condition of equilibrium and secure
the load if necessary.
Never step under overhead loads - danger of being injured!
Moving parts must always be secured against slipping or moving.
Required minimum load bearing capacity of the means of transport:

1.6 Warranty conditions
User Conversions and Changes are Not Permitted
The linear actuator must not be changed in its design or in terms of safety without our
approval. Any change as defined here made by the user excludes any liability on our part.
1.7 Conditions of utilization
General introductory notes
With the ETH electro cylinder you bought a product which was manufactured and tested
before delivery with the utmost care.
Please take your time to read the following notes which you ought to follow closely during
setup and operation.
The operation of the electro cylinder is only permitted within the limit values stated in this
manual.
Unless, all claims under the warranty will become void and a reduced service life or even
damages must be expected.
Please compare the operating data with the stated limit values especially with
reference to:
◆Stroke length and setting of the limit switches, those must be set so that there is a sufficient
safety travel at both ends of the travel stroke
Even if the limit switches were already mounted at our premises, they must be adapted
according to suitable values before operation!
◆Thrust and traction force in the effective direction
◆Lateral force (e.g. as a component of the effective force, but also due to own weight on
horizontal mounting, especially with parallel motor mounting and long travel strokes)
◆Speed
◆Acceleration
◆Environmental conditions (e.g. temperature, contamination)
◆Please do take possible pulses caused by moved masses into consideration for the
operating data. (Even small abrupt loads can cause damage, especially if they occur rather
often at the same place.)
The limit values for the thrust and traction force, lateral force, speed and
acceleration are partly influenced by several factors and can change depending on:
◆the size of the electro cylinder
◆Screw lead
◆Direct or parallel drive via toothed belt transmission
◆Mounting method
◆Mounting orientation vertical or horizontal resp. inclined
◆Travel Stroke

Parker EME/ EMN
Introduction
192-550002N2 ETH Mounting instructions March 2011 13
If the motor used with the electro cylinder should be able to exceed individual limit values of
the cylinder, the respective values for the motor must be limited in the control by
appropriate parameterization. The parameterization should even be reduced down to the
values necessary for operation.
This would, for example provide a hint to a possible damage or to preventive maintenance
if wear-induced extensive friction of the machine or cylinder would trigger an error message
of the controller.
The internal end stops of the electro cylinder may under no circumstances be
accessed during operation. The internal end positions may only be accessed by the
cylinder in setup mode and only for determining the end positions with a low force of
a few N (torque limitation if possible below 10%) and very slowly (max. 2% of the
nominal speed).
The lifetime of the electro cylinder depends strongly on the degree of power exploitation
and on impermissible operating states occurring - even if only for a short time.

The linear module is furnished completely mounted and mechanically ready-to-operate.
If no Parker drive is provided, attach your motor-gearbox combination according to the
instructions of the respective supplier.
The technical data must be respected.
See from page 6 in the catalog section (following the mounting instructions).
2.1 Mounting
Caution!
Please use only the parts offered in the Parker ETH catalog for the following
mounting components:
◆Rear Eye Mounting (order code E)
◆Rear Clevis (order code C) with bearing pedestal
Standard parts in accordance with the ISO flange standard cannot be used for
these accessories, as they are not sufficiently stable.
Please Note:
◆The cylinder housing must be mounted without tension or contorsion.
◆The cylinder housing must be precisely aligned to the load direction of motion.
◆Occurring lateral forces on the cylinder must be taken into consideration.
2.1.1. Mounting with mounting threads on the cylinder
The easiest and most economic method of mounting is using the available mounting
threads on the cylinder body. Make sure that the mounting surface is level and that the
cylinder is mounted without tension and contortion. This method of mounting is only
possible, if the lower side of the mounting surface is accessible.
Dimensions: see in the catalog section (following the mounting instructions) on page 16.
2.1.2. Mounting with mounting accessories
Cylinder mounting with mounting plates or foot mounting brackets
If the underside of the mounting surface is not accessible, mounting plates or foot mounting
brackets are available as accessories.
Mounting methods: see from page 19 in the catalog section (following the mounting
instructions).
Dimensions: see in the catalog section (following the mounting instructions) on page 16.
The rear mounting plate cannot be fixed with inline motor configuration.
If you fix the cylinder only at the rear end (e.g. also with a rear clevis) please respect the
effective direction of the known forces. Critical are above all lateral forces in horizontal or
vertical direction.
Permissible side load: See from page 13 in the catalog section (following the mounting
instructions).

thrust rod. Solution: On the cylinder rod there are spanner flats for locking, see
dimension “SW” (width across flat) “Thrust rod version”: see in the catalog section
(following the mounting instructions).
Connect the payload always with the end of the thrust rod so that occurring lateral
forces are minimized. If the payload is separately guided, even minimal deviations
between this guiding system and the cylinder length axis can generate high lateral
forces and reduce the service life of the electro cylinder considerably.
There are two possibilities to avoid this problem:
◆Use a flexible coupling at the thrust rod end.
This coupling can compensate up to 3 mm axial offset and up to 10angular
offset.
◆Use other thrust rod connection elements (accessories), which are able to
compensate certain deviations such as for example rod clevis or spherical rod
eye
◆Use a flexible cylinder fixing device (accessories) such as for example rear clevis
or center trunnion.
Thrust rod version: see from page 23 in the catalog section (following the mounting
instructions).

2.2 Electric installation
2.2.1. Sensors
All electro cylinders feature a permanent magnet in the spindle nut. It activates the limit
switches which are mounted in the special mounting grooves on one side of the cylinder.
Sensors and limit switches: see from page 28 in the catalog section (following the mounting
instructions).
2.2.2. Sensor mounting
◆Sensors can be inserted in all grooves on the ETH electro cylinder.
◆If no sensors are mounted by the manufacturer (on customer request), please remove
the groove protection covers. Use a pointed screwdriver to lever the ends of the covers off
the grooves. Pull the entire cover out manually.
◆Install the magnetic cylinder sensors. The sensors can be inserted into the grooves from
above. The cable ends should lead into the drive direction. Push the sensors to their
approximate positions in the grooves of the cylinder body. Tighten the fixing screws on the
limit switches slightly and lead the cable along the profile groove.
◆If sensors are used as end limits (see on page 18), do set them.
◆You can use the formerly removed protective
covers in order to fix the sensor cables. Please
cut the covers to the desired length with the aid
of a pair of scissors. Please cut off an additional
5 to 10 mm, where the cables are to be lead out
of the profile.
◆Insert the cables into the grooves of the plastic covers and push the cover into the groove
together with the cable.
◆Connect the sensors to the controller.
Sensors and limit switches: see from page 28 in the catalog section (following the
mounting instructions).

2.2.4. Setting the end limits
The steps described below can be best executed with energized drive.
Therefore, they may only be performed by trained and authorized personnel.
Do only travel at very low speed (<10 mm/s) and reduce the drive torque to a
minimum.
Ensure that there are no persons in the hazardous area.
The setting of the end limits depends on the application.
No sensor is to be mounted in the area of the central lubrication port
(option).
The following activation positions at the mechanical end limits result from the
initiators recommended in the catalog.

Caution!
Please add the respective safety travels to the values mentioned above”
Stroke, usable stroke and safety travel: see in the catalog section (following the
mounting instructions) on page 14.
Sensors and limit switches: see from page 28 in the catalog section (following the
mounting instructions).
Adjusting the machine zero proximity switch
The correct position for the home switch (machine zero switch) depends on the
application
It is recommended to set the machine zero at or near the end of the travel - this
saves time, as it minimizes the chance that the machine zero is searched for in the
wrong direction. In some cases it is possible to use one of the limit switches as
machine zero, this method provides however a reduced precision, as the resulting
position can normally not be and-linked with the encoder index pulse.

2.3 Motor and feedback mounting
In this chapter you can read about:
Motor / gearbox mounting with inline motor configuration.................................................20
Motor / gearbox mounting with parallel motor configuration .............................................21
Notes on motor wiring
In order to adhere to the EMC directive, it is necessary to mount the motor if ever
possible unchanged. If you require a longer cable, the entire line should be
replaced with the same or a similar cable.
If you mount a connector on the new cable, please make sure that the 360 °
motor cable shielding is maintained and that there is no connection to earth via
the connector housing.
The motor must be grounded with a separate PE protective lead
(green/yellow, cross-section at least 2.5 mm2).
This cable must be connected to the available motor-ground connector or - if there
is none available - with a mounting screw. In the latter case, the coloring under the
head of the screw must be removed.
If the axis is mounted upright, it must be secured against moving out!
