The Advanced charger building has been simplyfied because the user display and keys are mounted on a separated PCB linked to the main via a standard flat cable for very easy wiring. Please refer to the total charger building diagram for correct operations.

For wiring we recommend a silicon wire of at least 6sqmm. The preferred panel connectors are the 4 mm red/black plugs.
The polarized component orienetation is the following:

1. The power mosfets and the power diode have the tab to the board external.
2. The LM7805 has the tab to the board external.
3. The dual in line ICs have the pin 1 with a square pad.
4. The panel connector has the pin 1 with a squre pad (an arrow on the connector).
5. The fan connector has the pin 1 square, the center pin GND and the last pin +12V.
6. The polarized capacitors are marked on the assembly (+ sign for positive).
7. In the panel, the connector from main board is mounted on the bottom layer.
8. In the panel the buzzer is mounted on the bottom layer.
9. The display face, the DEM9P connector base and the keys should stay at the same level (box front panel).
10. The wiring for PCB and connectors is presented in the below figure. Please note the connection from the battery force minus and power supply minus in order to minimize the current flowing in the battery sense minus wire during the charge process.
