How to proceed
1. Clean contact surfaces of actuator and linear thrust
unit.
2.
Assembly may differ depending on the actuator:
For 2SL781/2 actuator:
a) Place actuator on linear thrust unit and
slightly tighten using the provided screw with
washers (fig. 1, pos. 1).
b) Fasten screws evenly crosswise while re-
specting the torque, refer to table below:
For 2SL783/4/5 actuator:
a)
Unscrew flange (fig. 2, pos. 1) from linear
thrust unit (pos. 2).
b)
Fasten flange to actuator.
c)
Fasten flange to actuator (fig. 3).
d)
Place actuator on linear thrust unit (fig. 4)
and slightly tighten using the screws with
washers.
e) Fasten screws evenly crosswise while re-
specting the torque, refer to table below:

2�3 Stroke limitation
■
With linear thrust units, stroke is limited by
end stops. These end stops may not be
approached in motor operation. Not even as
stroke limitation for torque tripping. This could
lead to linear thrust unit damage.
■
The mechanical end stops of linear thrust
units are not required when operating the de-
vice in standard operation mode. They serve
the purpose as “second protection” against
manual operation beyond the desired setting
range.
■
In the factory, the mechanical end stops are
adapted to the defined maximum stroke of
linear thrust units. Changing this maximum
stroke is not possible (refer to subsequent
chapter, item 2.).
