Instruction:
1.Remove basically all outside screws for your Anet A8 control box
2.Take pictures of existing board wiring
3.Unscrew two large 12 / 14GA wires on the board labeled HOT BED
4.Screw these two wires into the new MOSFET board labeled HOT BED
5.Connect the small jumper wires (white) to the control board where 6.you just remove the two wires and screw them down. Note the 7.polarity on each board. Match ( + ) to ( + ) and ( - ) to ( - )
8.Find 2 x 6 - 8 inches pieces of 12 or 14 AWG wire
9.Run one of the 6 inches wires to the power supply ( + ), screw in. 10.The other side to the (+) DC on the new MOSFET board. Repeat for the negative wire (-) to (-)
11.many people use Velcro to secure the new board to the top of the control box.
12.Put everything back together
13.when complete, you'll see a blue light activate for signal from inside the box when the bed heater is activated by the control board

Feature:
1.Effectively solve the problem that the heat bed power is too large and the load current issue
2.Helps 3D printers with controller boards (capable of max 15A) become more powerful
3.With this additional module, the maximum current on the board can reach 25A

Note:
1.This module under the premise of normal cooling, found at I (Max) = 25A stable work situation, the process of using the current not exceed 25A.
2.If your total power usage is 240W, and you have a 12V power supply, that means you need at least 20A (20x12=240W)

Package includes:
2 x Heated Bed Module
2 x Connection cable for input signal
8 x Fork type cold press terminal
