However, it’s imperative that the unit is not mounted on any unearthed metal surface to ensure safety and proper functionality.
Before commencing the mounting process, carefully remove the Electronic 7 from its mounting box. This is achieved by unscrewing the two captive screws that securely hold the unit in place. These screws are designed to remain attached to the unit, preventing loss during installation.
For conduit box mounting, ensure compatibility with the Electronic 7’s dimensions. The mounting box should be securely affixed to the wall, providing a stable base for the controller. When mounting, consider accessibility for future maintenance and programming adjustments.
Always prioritize safety during installation. If you’re unsure about any aspect of the mounting process, consult a qualified electrician. Proper mounting not only ensures the unit’s stability but also contributes to its overall lifespan and reliable performance.
Remember to consult the complete installation manual for detailed diagrams and specific instructions tailored to your particular mounting scenario. Following these guidelines will guarantee a safe and effective installation of your Horstmann Electronic 7.
Wiring and Connections
Proper wiring is crucial for the safe and effective operation of the Horstmann Electronic 7. Before commencing any wiring work, always isolate the power supply to prevent electrical shock. Refer to the wiring diagram included in the installation manual for accurate guidance.
For connecting the unit to the power supply, utilize a three-core cable with a minimum conductor size of 1.0 mm² for heaters up to 3kW. Ensure that the cable is appropriately rated for the voltage and current requirements of the Electronic 7 and your immersion heater.
Carefully connect the live, neutral, and earth wires to the corresponding terminals within the Electronic 7’s wiring compartment. Double-check the connections to ensure they are secure and properly tightened to prevent loose connections, which can lead to overheating or malfunction.
If you are connecting the Electronic 7 to control two immersion heaters, ensure that each heater is wired correctly according to the wiring diagram. Pay close attention to the load capacity of the controller and avoid exceeding the maximum rated current.
After completing the wiring, thoroughly inspect all connections and ensure that the wiring is neatly arranged within the compartment. Replace the cover securely, ensuring that no wires are pinched or exposed. If you are uncertain about any aspect of the wiring process, consult a qualified electrician for assistance. Incorrect wiring can be dangerous and may damage the unit.
