  • Page 9 Attach New Power Harness Connect the old power connector to the new power harness adapter found in the kit. The connectors are keyed - the power connectors only fit one way. New Power Harness Run the green ground wire from the power harness adapter between the bus bar and the enclosure wall avoiding any interference with other wires in the enclosure.

  • Page 14: Enclosure Door

    Enclosure Door Remove the old Sensor beacon acrylic in the door and discard by loosening the two retaining screws with a #2 Phillips screwdriver. Install the Sensor3 beacon acrylic in the door with the longer edge toward the center of the door. Carefully peel the old Sensor label from the front of the door and discard.
  • Page 15: Final Steps

    For future service needs, it is recommended that you send copies of the final CEM3 configuration files for each enclosure to ETC technical services (Lightmanager@etcconnect.com). Include your job number and the date the configuration was adjusted. Note: Send CEM3 configuration files saved out of the Sensor3 enclosure, not configuration exported from ETC Concert (if used).
