Installation should be performed by a qualified electrician in accordance with local safety regulations. The mechanism is designed to be mounted into a standard flush-mounted electrical box. Ensure that the power supply is disconnected before beginning the wiring process. Connect the motor leads to the designated terminals on the switch, ensuring that the up and down phases are correctly identified to match the desired switch orientation.
What to consider before purchase
Verify the compatibility of your motor's current requirements with the switch specifications.
Ensure the installation depth of 32 mm is sufficient for your existing wall boxes.
Confirm that the IP20 rating is appropriate for the intended indoor location.
