Introduction

Upgrading your Control Interface Box (CIB) with a relay replacement kit is a straightforward process that can significantly improve the performance and longevity of your system. In this article, we’ll provide you with a detailed, step-by-step guide to help you successfully install a CIB relay replacement kit. (A video tutorial will be included at the end of this article.)

Step By Step Instructions

Step 1: Turn Off Power

Before starting the installation process, ensure that the power supply to your Control Interface Box is completely turned off. This is a crucial safety measure that will prevent any electrical hazards during the installation.

Step 2: Remove Wires Going to Terminal Block

Carefully disconnect wires that are connected to the left side of the terminal block of your Control Interface Box.

Step 3: Loosen Fuses and Relays from the DIN Rail

Using a slotted screwdriver, gently loosen the fuses and relays to the DIN rail. Disconnect the wire going into the terminal below the DIN rail marked “24V DC Signal Out.”

Step 4: Move Wires to New Relay Kit

Take the new relay kit and connect the wires that were previously connected to the old fuses and relays. Ensure that the connections are secure and correctly aligned with the corresponding terminals on the new relay kit.

Step 5: Attach New Relay Kit to DIN Rail

Attach the new relay kit onto the DIN rail.

Step 6: Reattach Wires to Terminal Block

Reconnect the wires that were previously removed from the terminal block of your Control Interface Box. Make sure that each wire is connected as it was previously.

Step 7: Reattach Wire to 24V DC Signal Out Terminal

Finally, reconnect the wire that was previously attached to the 24V DC Signal Out terminal on your Control Interface Box.

Conclusion

Now that you’ve successfully installed the Control Interface Box relay replacement kit, you can turn the power supply back on and enjoy the improved performance and reliability of your system.
