Technical Data





  • We strongly recommend that all neptronic® products be wired to a separate transformer and that transformer shall service only neptronic® products. This precaution will
    prevent interference with, and/or possible damage to incompatible equipment.

  • When multiple actuators are wired on a single transformer, polarity must be observed. Long wiring runs create voltage drop which may affect the actuator performance.

Mechanical Installation

  • Manually close the damper blades and position the actuator at 0º or 90º.
  • Slide the actuator onto the shaft.
  • Tighten the nuts on the “U” bolt to the shaft with a 10mm wrench to a torque of 150 [17 Nm].
  • Slide the mounting bracket under the actuator. Ensure free movement of the slot at the base of the actuator. The bracket pin must be placed in the mid distance of the slot.
  • Fix the bracket to the ductwork with #8 self-tapping screws.
