Safety advice
3 Safety advice
Depending on the technical circumstances and the time under and at which the electric actuator
is mounted, adjusted and commissioned, in each case you have to take into account particular
safety aspects
If, for example, the actuator actuates a slide in an operational chemical plant, the potential hazards
of commissioning have another dimension from that when this is only being carried out for test
purposes on a „dry“ part of the plant in the assembly room.
Since we do not know the circumstances at the time of mounting / adjusting / commissioning
you may find advice on hazards in the following description which are not relevant to you. Please
observe (only) the advice which applies to your situation!
The actuators must not be put into service until the final machinery into which it is to be incorpo-
rated has been declared in conformity with the provisions of the Directive 2006/42/EC on machin-
ery, where appropriate.
3.1 Personal protection
3.1.1 Safety advice for mounting
We wish to point out expressly that the mounting, the electrical installation and the adjustment
of the actuator NE and the accessories must be carried out only by trained specialised personnel
having mechanical and electrical knowledge.
Switch off all the devices / machines / plant affected by mounting or repair.
If appropriate, isolate the devices / machines / plant from the mains.
Check (for example in chemical plants) whether switching off the devices / machines / plant will
cause potential danger.
If appropriate, in the event of a fault in the actuator (in a plant which is in operation), inform the
shift foreman / safety engineer or the works manager without delay about the fault, in order, for
example, to avoid an outflow / overflow of chemicals or the discharge of gases in good time by
means of suitable measures.
Before mounting or repair, remove the pressure from the pneumatic / hydraulic devices /
machines / plant.
If necessary, set up warning signs in order to prevent the inadvertant starting up of the devices /
machines / plant.
Observe the respective relevant professional safety and accident prevention regulations when
carrying out the mounting / repair work.
Check the correct functioning of the safety equipment (for example the emergency push off but-
tons / safety valves, etc).
Before electrical installation of the actuator, check the voltage-free state of all lines to be con-
nected.

NE03 - 01.2020 http://www.end.de 9
Safety advice
3.1.2 Safety advice for adjustment and starting
As a result of the starting (electrically or by hand) of the actuator, the position of a slide / valve /
flap or the like on which it is flange-mounted - referred to below as the actuating element - will be
changed!
As a result, the flow of gases, steam, liquid, etc. may be enabled or interrupted.
Satisfy yourself that, as a result of the starting or the test adjustments on the actuator, no potential
hazards will be produced for personnel or the environment!
If necessary set up warning signs in order to prevent the inadvertent starting up or shutting down
of the devices / machines / plant!
After completing the adjustment, check the correct function and, if appropriate, compliance with
the intended angular position of the actuator and the function of the switches of the adjusted to
the angular positions!
Check the function of the end position switches.
Check whether the actuating element is actually 100 per cent closed when the controller signals
the corresponding end stop.
Through suitable measures, prevent that limbs being trapped by moving actuating elements!
Check the correct function of the safety devices (for example emergency push off buttons / safety
valves, etc.
Carry out the starting or the adjustment only in accordance with the instructions described in this
documentation!
In case of adjustments on an actuator which is open and switched on (ready to use), there is a
risk that live parts can be touched.
The adjustments must therefore be carried out only by an electrician or a person having adequate
training, who is aware of the potential hazard.

5 Ambient conditions
The actuators NE are designed for rough operating conditions.
However, some special conditions are to be observed for its mounting and subsequent operation.
Take care that
• the actuator will be mounted in accordance with the mounting advice listed below.
• the actuator is used in accordance with the characteristic values specified on the
name-plate or in the separate data sheet.
• mounting of the outdoors only after request.
• the actuators must be protected from environmental influences (e.g. UV radiation, frost,
humidity).
The non-observance of the mounting advice or use outside the specified characteristic values can
have a negative influence on the functional reliability of the actuator.
The use of the actuator under the influence of radioactive radiation may take place only after
discussions with the manufacturer
Ambient conditions

NE03 - 01.2020 http://www.end.de 15
6 Assembly instructions
The mounting of the actuator NE is restricted to
• the mechanical mounting of the actuator on the part of the devices / machines / plant
which contains the actuating element, and
• the connection of the actuator to the motor drive and control lines.
The actuator may be mounted in any desired position.
In the following description, we assume that you have carefully read the previous chapters and
that you will observe the safety advice and the warning notes in chapter 3 „safety advice“ during
the mounting / disassembly work.
If you have not yet read chapter 3 „safety advice“ please do so now and then return to this point!
The mounting and the electrical installation may be carried out only by trained specialist person-
nel with sound mechanical and electrical knowledge.
The mechanical mounting is identical in all variants.
The electrical installation is different, depending on the type of drive an equipment.
Therefore, for the electrical installation, observe the wiring diagrams at the end of these mounting
and operating manual
The explanation of the designation will be found under
4.3 “Device variants”.
6.1 Mechanical mounting
Two mounting variants are available:
• directly mounting, or
• mounting with bracket and stem (accessory)
Before mounting you have to fix a qualified mounting variant for your application.
Directly mounting will be able, if the dimensions of the shafts and the ISO - flanges of the actuator
and the slide/valve/flap are the same. Differences of the dimension for the stem of the slide/valve/
flap will be able to be equalized by available bushings (option) in some cases.
A mounting with bracket and stem will be necessary, if the differences of the dimensions between
the shaft of the actuator and the stem of the slide/valve/flap are not able to be equalized by a bush-
ing or the ISO-flanges did not match.
This mounting variant will also be used by high/low medium temperatures or voluminous isolated
pipes.
By mounting with bracket and stem observe also the mounting device of the supplier of these parts.
Do not drill any holes into the body of the actuator- the damage of the actuator or a insufficient
fastening of the actuator will be the result.
Assembly

16 http://www.end.de NE03 - 01.2020
6.1.1 Directly mounting
Before starting the assembly of actuator and slide/valve/flap, observe that the actuator and the
slide/valve/flap are in the same end position, e.g. both in OPEN or in CLOSE position. Furthermore
the operating direction on actuator and slide/valve/flap must be the same.
Put the bottom side of the actuator to the slide/valve/flap that the stem will enter into the octagonal
boring of the shaft of the actuator. If necessary use a appropriate bushing (options), to equalize
differences of the dimension between the stem and the shaft.
Align the actuator to the slide/valve/flap.
Put the actuator onto the stem of the slide/valve/flap until the surface of the actuator cling to the
ISO - flange of the slide/valve/flap. If this operation will be ponderous the shaft of the actuator will
be driven onto the stem of the slide/valve/flap by slightly strokes without any tools.
Fasten the actuator with fit bolts. Observe the maximum depth of the threaded holes of the actua-
tor. Would there be two sizes of hole circles to fasten the actuator, you have always to use the
greater one.
Tighten the screws. Therefore observe the maximum torque of the choused screws.

6.1.2 Mounting via bracket and stem
Before starting the assembly of actuator and slide/valve/flap, observe that the actuator and the
slide/valve/flap are in the same end position, e.g. both in OPEN or in CLOSE position. Furthermore
the operating direction on actuator and slide/valve/flap must be the same.
Put the stem onto the stem of the slide/valve/flap. Therefore observe the position of possibly posi-
tion indicators.
Put the bracket onto the slide/valve/flap and align them .
Fasten the bracket with fit bolts. Observe the maximum depth of the threaded holes of the actuator.
Would there be two sizes of hole circles to fasten the actuator, you have always to use the greater
one. Tighten the screws. Therefore observe the maximum torque of the choused screws.
Put the bottom side of the actuator to the slide/valve/flap that the stem will enter into the octagonal
boring of the shaft of the actuator.

6.2 Electrical Installation
Please be sure that the voltage of the power supply must be in accordance with the specification
of the name-plate
Protect the electric actuator appropriate to the current consumption.
Connect the actuator each with its own switching device.
6.2.1 Removing of the housing cover
Loosen the four socket screws with an Allen key and pull the housing cover hard to remove it!
For assistance, you can insert a screwdriver a few millimetres between housing cover and hous-
ing and lever the cover open..
Do not damage the cover and/or the sealing rubber in the process. In this case, the degree of
protection IP 67 would no longer be ensured!
6.2.2 Stripping and connecting the cables / leads
Take care that all leads which have to be stripped and connected during the installation work
have all their poles isolated from the power supply.
When stripping leads which are live, there is a risk of a life-threatening shock.
Remove the sheaths of the motor drive cable and the control cable and the insulation from the
leads in accordance with figure 6.3.
In the case of leads with stranded conductors, provide the ends in each case with a wire end
sleeve.
Lead the cable for the motor and the cable for the limit switches through the cable fittings.
Feed the stripped ends of the leads into the terminals as far as the stop and then tighten them. The
assignment of the connections can be seen from the wiring diagrams at the end of these mounting
and operation manual.
At actuators witch are provided with options additional operating manuals enclosed if possible.
Please take notice of this manual, the references and the appropriate wiring diagram.

Don’t miss to connect the two ground earth (Internal one marked by sticker, outer is between the
mechanical bolt stops (see figure 6.5) ).
Ensure that no bare wires protrude from the terminals and thus produce the risk of a shock or of
a short circuit.
Tighten the cable fittings so firmly that the strain relief becomes effective and the cable lead
through corresponds to the predefined degree of protection (IP67).
Bend the leads in the actuator such that they are not trapped when the housing cover is fitted.
Lay the cables to their starting positions (as appropriate, in conduits or cable ducts).
Observe that no moisture come into the actuator along the cable. Install the cable by a bow into
the actuator by example, so that moisture can drip of.
Ensure that the cables are not crushed or sheared and that they are not under pressure or tension.
Do not lay the control cable parallel to other cables which lead to high-power loads. Powerful
electromagnetic fields could induce currents in the control lines which may possibly lead to
malfunctions.
Finally, carry out the adjustments to the actuator, for this please observe the chapter
7. „Adjustment / Starting“
Close the actuator again.
Ensure that the circumferential rubber sealing ring in the housing is not damaged and correctly
seated in the groove.
Fit the housing cover and screw it tight using the 4 screws. For this, observe the chapter
7.6 „Fitting the housing cover“.
