How to use

To install the ZB4BW34, ensure the control panel is de-energized. Insert the push-button head into a standard 22 mm mounting hole on the panel front. Secure it using the provided locking nut from the rear. Once mounted, attach the appropriate contact blocks and light modules from the Harmony XB4 series to the back of the head. Ensure all connections are tightened according to the manufacturer's torque specifications before restoring power.

What to consider before purchase

• Verify that your existing control panel has a 22 mm mounting hole.
• Ensure compatibility with your specific Harmony XB4 contact blocks and light modules.
• Confirm the required voltage for the illumination module you intend to pair with this head.
• Check the environmental conditions of your installation site to ensure the IP rating meets your requirements.

Usage recommendations

Regularly inspect the actuator for signs of wear or debris accumulation to maintain optimal visibility and mechanical performance. Ensure that the light module is correctly seated to prevent flickering or connection failure.
