1. Prepare actuator and mount possibly re-
quired adapter supplied by the actuator
manufacturer (only necessary for fixing
level 2).

actuator. In case of VDI/VDE attachment,
place spacers (8) underneath, if neces-
sary.

and VETEC R Rotary Actuators, screw
the adapter (6) with the supplementary
adapter (depending on the mounting kit)
onto the free end of the shaft of the actu-
ator. For VDI/VDE version, only place on
the adapter (6) when it is required for
the actuator size.
4. Stick adhesive label onto the coupling
wheel (5) in such a manner that the yel-
low part of the sticker is visible in the
window of the housing when the valve is
OPEN. Adhesive labels with explanatory
symbols are enclosed and can be stuck
on the housing, if required.
5. Fasten coupling wheel (5) on the slotted
actuator shaft or adapter (6) using screw

7. Fasten the limit switch onto the mounting
plate (2).
8. Place the limit switch together with the
mounting plate on the enclosure (7) and
screw it tight. Taking the actuator's direc-
tion of rotation into account, adjust lever

with its follower pin.
