I Understand The Risks
¶ Electronics — V-Core 4 Main Wiring
This page contains the necessary information to wire the AC circuit of a V-Core 4. Always double-check every connection and wiring diagram.
WARNING! Before beginning this guide, ensure that the machine is powered off and disconnected from the mains outlet.
¶ Before Getting Started — How to Crimp
Ensuring good crimps on 230V circuits is critical for both safety and performance. Crimps provide a secure and stable connection between electrical wires and terminals, essential in preventing loose connections that can lead to overheating, short circuits, or electrical fires. A properly executed crimp ensures low resistance and high conductivity, which is crucial for maintaining the efficiency and reliability of the electrical system.
¶ Prepare the Following Parts
Prepare all the wires, as shown:
Ensure that each wire is complete with a fork connector and a spade connector at both ends, with the exception of the 1500mm YellowGreen wire. This specific wire must have a fork crimp on one end and a ring terminal on the other end, as illustrated below:
¶ Prepare the Fuse Holder
Remove the fuse holder cap by gently twisting it with a flat screwdriver. Then, insert the 15A fuse and proceed to reinstall the cap. Firmly press the cap down before rotating it to ensure the spring is fully compressed against the fuse.
WARNING! Never connect the power cord to the IEC without finishing all connections and installing the AC cover. Triple-check all connections, as a misplaced wire can cause serious damage and injury.
¶ Install the 230V Wires
Install the 230V wires, ensuring the fork connector is on the power supply end of the wires and the spade connector is fully inserted into the IEC and fuse holder. The long 1500mm Yellow-Green wire must be fed through the rear panel hole and screwed to the bed plate.
Before connecting to power, pull on the cables to verify if all connectors are secure!
¶ Connect the Bed Heater
Pass the bed heater wires through the opening in the electronics panel. The image below illustrates the necessary connections on the right side and the required components on the left side. You will need the bed heater and a small, pre-crimped cable.
Pull on the cables to verify if all connectors are secure!
¶ Verify the Main Power Diagram
Your main power circuit should look like this. Remember to triple-check every connection and install the AC cover before connecting the power cord.
Before connecting to power, pull on the cables to verify if all connectors are secure!
Warning for users in countries with 110V mains: Before connecting the power cable, inspect its rating. Ensure the cable is labeled with the correct voltage and current ratings for your electrical installation. If you are uncertain about which power cable to use, seek advice from a certified electrician. Rat Rig recommends using a power cable rated for 20A.
¶ Reinstall the Covers
Reinstall the AC cover and the main electronics cover before powering up the machine.
