Electric connection

RESPECT SAFETY INSTRUCTIONS
The caps placed on M20x1.5 openings (appendix p.14 mark 15) must be replaced by ATEX certified connection glands.
•
Remove the position indicator, unscrew the four screws and take off the cover.
SUPPLY AND CONTROL WIRING (Except POSI - see p.22)
•
Ensure that the voltage indicated on the actuator ID label (appendix p.31/32 mark 11) corresponds to the voltage supply.
•
Connect to earth through the exterior bolt M5 located under the cable gland (appendix p.31/32 mark 16). It is also possible
to connect the actuator to earth inside the actuator through the bolt M3 next to the terminal strip (appendix p.17 mark A).
•
Unscrew the left cable gland and insert the cable.
•
Connect the wires to the terminal strip (appendix p.17 mark B) in accordance with the required control mode.

•
Put a lacing cord around the wires (see the picture beside) and re-tighten the cable gland.
WIRING OF THE FEEDBACK SIGNAL
Our actuators are equipped with two simple limit switch contacts normally set in their
open position (NO). As per factory setting, the white cam is used to detect the open
position (FC1) and the black cam is used to detect the closed position (FC2).
This feedback system accepts voltages between 24V and 240V AC/DC.
•
Unscrew the right cable gland and insert the cable.
•
Remove 25mm of the cable sheath and strip each wire by 8mm.
•
Connect the wires to the terminal strip (appendix p.31/32 mark 12) in accordance
with the diagram beside.
•
Tighten the cable gland.
SETTING OF END LIMIT SWITCHES
The actuator is pre-set in our factory. Do not touch the two lower cams in order to avoid any malfunctioning or even damage to
the actuator.
•
To adjust the position of the auxiliary contacts, make rotate the two superior cams by using the appropriate wrench.

NOTA BENE : The used wires must be rigid (feedback volta-
ges : 4 to 250V AC/DC)
NOTA BENE: The actuator is always powered, so it must be
connected to a disconnection system (switch, circuit breaker) to
ensure the actuator power cut.
