Consider prior to attachment of couplings:
•
Do not turn actuator shafts by force;
•
actuator and valve shafts must run centric.
For all actuators observe the following advice:
The initial operation of the actuator is only permitted with orderly closed cover and closed cable entries. Use only cable glands
which are appropriate for the respective protection class.
•
Cable entries
Ensure that all cable entries are closed properly during storage, installation and initial operation.
Use only cables which are suitable for the diameter of the cable entries.
•
Cover assembly
During the cover assembly make sure that the cover fits correctly.
The cover must not show any damages on the joint surface.
Tighten cover screws evenly (max. 1.2 Nm).
No additional bores are allowed to the enclosure and the cover.

Initial operation
4.5.1
Electrical connection
Hazardous voltage: Possible stroke!
•
The initial operation must be carried out only by experts!
•
De-energize the actuator before opening.
•
Observe the appropriate regulations during electrical installation and initial
operation.
Connect the actuator as follows (wiring diagram see chapter 4.5.2):
•
Connect the ground wire of the electric supply to the appropriate protective earth terminal.
•
Always refer to the wiring diagram located inside the actuator.
Check prior to initial switching on:
•
Is the actuator undamaged on the outside?
•
Is the mechanical connection correct?
•
Has the electrical connection been made regularly?
•
Check if current type, voltage and frequency match with the motor data (see nameplate on cover and inside the actuator).
•
Insert suitable cable glands for the connection line.
•
Use separate (shielded) wires for low voltages.
•
Set up limit switches prior to initial operation.
