Assembly notes
• Check the relevant national safety standards are respected.
• The connection between the actuator command shaft and the
control element must be rigid, without any mechanical play.
• During the assembly of the servomotor, make sure that the ra-
dial and thrust loads acting on the bearing are not exceeded.
• When installing the servomotor to the control elements, proceed
as follows:
1 - Assemble and fix the servomotor.
2 - Connect the drive shaft of the servomotor by means of a lug.
Installation notes
• Arrange the H.V. ignition cables separately, as far as possi-
ble from the control box and the other cables.
• The holding torque is reduced when the servomotor is dis-
connected from the mains.
