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.
