Important Information

This document provides instructions for adding or replacing the Metal Oxide Varistor (MOV) assembly on 10260S Series Actuators. Before beginning, ensure you have the correct kit for your actuator's input voltage: Part # 51500671-503 for 120 Vac input or Part # 51500671-504 for 230 Vac input.

Safety Precautions

  • Disconnect Power: Always disconnect AC power to the actuator before accessing internal components.
  • Electrostatic Discharge (ESD): When working with Printed Wiring Assemblies (PWAs), wear a grounded wrist strap to prevent damage from electrostatic discharge.

Tools Needed

  • Medium Flat-blade screwdriver
  • Medium Phillips screwdriver
  • Small needle-nosed pliers

  1. Remove AC power to the actuator.
  2. Remove the four screws and the terminal cover from the side of the actuator case.
  3. Locate terminals TB1-1 (marked L) and TB1-2 (marked N) and the ground screw on the actuator terminal block.
  4. Remove the screws from terminals TB1-1, TB1-2, and the ground screw location.
  5. Install the MOV assembly. Attach the larger size lug terminal to the ground screw on the terminal panel. Attach the remaining lug terminals to TB1-1 and TB1-2 on the actuator terminal panel.
  6. Install a new gasket and the terminal panel cover. Secure the cover to the actuator using the four screws.
  7. Reapply AC power to the actuator.
  8. Verify the actuator configuration and check for correct operation.
  9. Return the actuator to service.
