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. 1 Enerdrive System U.S.A. Patent #5,278,454 Feature: • Mounts easy on round & square shaft (with option –8). • External clutch for manual adjustments. • Maintenance free. • Position indicator. • Fail safe by Enerdrive System1 (on model 60, 65 & 80). • Auxiliary switches (on model 20 & 80).

Manually close the damper blades and positioned the actuator at 0º or 90º. 2. Slide the actuator onto the shaft. 3. Tighten the nuts on the “U” bolt to the shaft with a 8mm wrench to a torque of 60 in.lb. [6,7 Nm]. 4. 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. 5. Fix the bracket to the ductwork with #8 self-tapping screws.
