To use the ZB4BD7, mount the switch head onto a compatible 22 mm diameter panel cutout. Ensure the locking nut is tightened securely to maintain the integrity of the IP67 seal. Insert the provided key into the cylinder and rotate it to the desired position to engage the internal contact blocks. Always ensure that the contact blocks are correctly installed on the back of the switch head before operation.

What to consider before purchase

• Verify that your control panel has a 22 mm mounting hole
• Ensure the key-operated function meets your safety requirements
• Check compatibility with existing Harmony XB4 contact blocks

Usage recommendations: Regularly inspect the key cylinder for debris and ensure the switch operates smoothly. For optimal performance, keep the key in a secure location and avoid using excessive force when rotating the selector.
