Installation
Section 4: Installation
Replace the plastic plugs of the unused cable entries with metal plugs, to guarantee
perfect weather-proof protection and to comply with explosion-proof protection codes
(where applicable). Once the connections are completed, check that the controls and
signals work properly. Two ground studs, (one internal and one external) are provided
to meet all local electric and safety regulations. Terminate the ground connections at a
minimum to the external stud marked GROUND. Connect the motor supply cable previously
sized in accordance with:
• The absorbed current that corresponds to the actuator nominal torque with the
torque limiting device set at 100%
• Cable size: 1 power: 4 mm
2
/AWG12 (max) 2 controls: 1.5 mm
2
/AWG 16 (max)
• The applicable plant and safety norms
• For actuators certied according to CSA standards, the eld connections shall be
done with certied crimp-on ring terminals.

NOTE
1. Power connection L1-L2 for V DC or V AC single-phase motor supply from 24 V to
48 V or from 100 V to 240 V.
Power connection L1-L2-L3 for three-phase motor supply from 208 V to 575 V
(check the actuator label for the correct voltage to be applied).
2. Remote command options.
3. Contacts shown in intermediate position CLC1-CLC2 signal end of travel while closing.
Contacts shown in intermediate position OPC1-OPC2 signal end of travel while opening.
4. Output contact rating 240 V AC / 5 A ; 30 V DC / 5A ; 120 V DC / 0.5 A. Output
contacts (when used ) have to be feed with the same external voltage.
5. Control command rating 24 to 120 V AC or DC.
6. Blinker or Local Selector monitoring function (when OM3 is present) must be congured.
