Installation and mounting
•
Inspect the actuator for damages prior to installation;
•
the screw-in depth of connecting thread holes must not exceed 9 mm;
•
check leak tightness of cable glands and blank plugs prior to initial operation;
•
tighten the cover screws evenly (max. 1.2 Nm);
•
do not operate before limit switches have been adjusted;
•
protect the actuator against climatic influences (e.g. by a protective cover);
•
do not expose the actuator to hard shocks (e.g. by dropping);
•
do not attach ropes, hooks or the like to the actuator;
•
permanent overload and blocking leads to actuator damages;
•
spark suppressor capacitor can effect the rotation stability of the actuators and may cause damages;
•
use only ARIS original spare parts.
Consider prior to attachment of couplings:
•
Do not turn actuator shafts by force;
•
actuator and valve shafts must run centrical (possible adjustment by flexible coupling);
•
the attachment to the valve is made by actuator-attached brackets.
Installation position:
The actuators can be installed position independendly.
Protection class IP65
For all actuators observe the following advices:
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).
•
Housing/Cover
No additional bores are allowed in the housing and the cover.
