RESPECT SAFETY INSTRUCTIONS
Our cable glands (appendix p.31/32 mark 15) are designed for cables with a diameter between 7mm and 12mm. The used
cables must be able to withstand the ambient conditions (maximum temperature 70°C).
•
Remove the position indicator, unscrew the four screws and take off the cover.
POWER SUPPLY WIRING
•
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). For multivolt ver-
sion, it is also possible to connect the actuator to earth inside the actuator through the bolt M3 next to the terminal strip.
•
Unscrew the left cable gland and insert the cable.
•
Connect the wires to the power supply card's terminal strip (appendix p.31/32 mark 14).

•
Put a lacing cord around the wires (see the picture beside) and re-tighten the cable
gland.
POSITIONING CARD WIRING (OUTPUT AND INPUT SIGNAL)
In order to avoid electromagnetic perturbations, it is compulsory to use shielded cables (cables longer than 3m).
•
Unscrew the right gland and pass the cable.
•
Connect the input signal between terminals 15 and 16 (appendix p.27 mark B).
Terminal 15 is the negative polarity (-) and terminal 16 is the positive polarity (+).
•
Connect the output signal between terminals 13 and 14 (appendix p.27 mark B).
Terminal 13 is the positive polarity (+) and terminal 14 is the negative polarity (-).
•
Tighten the cable gland.
Factory setting : by default, 4-20mA input and output signals with normal rotation sense.
To proceed to a new setting of the card : please see next page, "Parameter selection sequence".
To check the proper operation of the card : please see next page, "Normal operating mode".
Type 0-20 or 4-20mA : 5V DC max.
The terminal temperature can reach 90°C
N.B.: The actuator is always powered, so it must be connected to a disconnection system (switch, circuit
breaker) to ensure the actuator power cut.
N.B.: The used wires must be rigid (feedback voltages : 4 to 250V AC/DC)
