5.3.4 Schematic diagram for direct current
CCW rotation:
Apply DC voltage to terminals L+
and L−.
CW rotation:
Apply DC voltage to terminals L
a
+
and L
a
− .

5.3.5 AC schematic diagram with service switch (option)
The service switch can be used to
move the actuator irrespective of
the control signals present at
terminals 2 and 3.
Hand = manual operation
Rechts = right-hand operation
(CW rotation)
Links = left-hand operation
(CCW rotation)

5.3.6 AC schematic diagram for parallel operation (option)
If several actuators are to be con-
trolled by a common switching
contact, every actuator must be
equipped with a relay for parallel
operation.
