10.1 Wiring diagram
Figure 10 shows the standard electrical connections. However, the wiring diagram inside the actuator hood
is valid for the specific actuator. For any optional extras see the individual wiring diagram in the related
service instructions.
Two adjustable limit switches are installed to limit the stroke of the actuator, and cut-off the motor current
in the relative direction.
PE Earth connection on housing plate has to be connected!

11. Commissioning
Drive the actuator into an intermediate stroke position using the hand wheel.
Switch the setting signal briefly between OPEN and CLOSE and ensure that the actuator operates in the
correct direction. If necessary, reverse the setting signal for OPEN / CLOSE.
Drive the actuator, in both directions, using the setting signal until the limit switch cuts-off. Ensure that
the limit switch position is correct. If necessary re-adjust the limit switches.
12. Service/ Maintenance
The actuators are maintenance-free if used under the operating conditions as stated in the data sheet. The
gearboxes are lubricated for lifetime and do not require further lubrication.
12.1 Cleaning
The actuators should be cleaned dryly.
